 <Click the picture to enlarge>




The award-winning Acura MDX luxury SUV sets even higher standards in 2010 for styling, performance, technology and safety. For 2010, the Acura MDX features a fresh new exterior look, revised powertrain that includes a new 6-speed automatic, chassis refinements, more comfort, and improved technology along with the introduction of an all-new Advance Package - making the class leader even better.

Visually, the 7-passenger 2010 Acura MDX receives more aggressive styling in the form of new front and rear bodywork, a bold new front grille and numerous new trim enhancements. Under the hood, the Acura MDX receives a more refined 3.7L V-6 engine that teams with an all-new 6-speed automatic transmission for better performance and improved fuel efficiency. Inside, the Acura MDX receives a host of new features and technologies that make it even more luxurious.

To expand the dynamic capabilities for 2010 MDX, a new Advance package, with a revised Active Damper System and larger 19-inch wheels and tires, further enhances handling while retaining the comfortable, quiet and controlled ride quality expected of a luxury vehicle.

The 2010 Acura MDX exterior gets a fresh new look as a result of Acura's signature design front grille, a new front fascia, revised hood, new side sills, a new rear fascia matched with rolled edge polished stainless-steel exhaust finishers, revised taillights with brighter LED lights, many new trim pieces and available 19-inch diameter 7-spoke aluminum-alloy wheels.

Inside, the 2010 MDX benefits from the expanded use of Milano leather, a new thicker sport steering wheel with racing-inspired paddle shifters, new gauges, easier to understand button placement for center stack functions, available ventilated front seats and upgraded interior trim. In addition, a host of new technology is available including AcuraLink Real-Time Weather and Traffic Rerouting. Other available features include a new full VGA 8-inch navigation screen, a new rear view camera with three unique view choices, upgraded rear entertainment system, an updated audio system with a dedicated 15 GB hard disk drive (HDD) and USB port connectivity, even more LED lighting - and the list goes on.

Powertrain
For 2010 the Acura MDX receives a new 3.7-liter VTEC V-6. The engine continues Acura's longstanding mission to provide V-8 level horsepower and torque while retaining the size and fuel efficiency of a V-6. Based on the previous Acura MDX's powerplant, the newly refined 3.7L V-6 develops 300 horsepower and 270 lb-ft of torque to provide immediate throttle response, outstanding low- and mid-range torque and excellent high-rpm power. To widen the powerband while simultaneously improving fuel efficiency, the latest 3.7-liter engine has the patented Variable Valve Timing and Lift Electronic Control (VTEC) system applied to the intake valves, revised high-lift camshaft specs during VTEC operation, a computer controlled dual-stage induction system and an electronic Drive-by-Wire throttle system.

Internally, the new 3.7L V-6 makes use of special heavy-duty components including a more rigid cylinder block, high-strength crankshaft, heavy-duty connecting rods, high compression-ratio pistons, cylinder heads with improved cooling, new intake valve springs, a new EGR system, unique long-reach spark plugs, a larger throttle body and other features.

EPA estimated city/highway fuel mileage of 16/21 mpg (an improvement of 1 mpg city and 1 mpg highway over the 2009 model) and a large 21-gallon fuel capacity mean the Acura MDX is perfect for long drives. Like all 2010 Acura vehicles, the MDX complies with the latest EPA TIER 2 - BIN 5 and CARB LEV II ULEV emissions standards.

The 3.7L V-6 is coupled with a brand-new Sequential SportShift 6-speed automatic transmission along with a new multi-clutch torque converter. With comparatively "short" gearing in the first five forward gears, acceleration is enhanced - while fuel efficiency and quiet cruising are optimized with a relaxed Sixth gear ratio. The transmission  two automatic shift modes, or can be operated manually via racing-inspired steering wheel paddle shifters. Grade Logic Control, Shift Hold Control, Cornering G Shift Control and Hill Start Assist make the new 6-speed the most advanced automatic transmission ever offered by Acura. To support the Acura MDX's 5,000 pound towing capacity, a special front-mount transmission fluid cooler is employed.

 
ChassisWith an emphasis on top-level handling performance, Acura MDX engineers targeted the world-class dynamics and driving feel of the top European SUV competitors. This led to the development of a long wheelbase platform and a sophisticated suspension system tuned at Germany's famed Nürburgring race circuit.

The Acura MDX's 4-wheel fully-independent suspension makes use of MacPherson struts in front teamed with a multi-link rear suspension design that is mounted to a rigid unit body structure with isolated subframes. The front suspension also uses unique hydro-compliance bushings that provide superior ride isolation and chassis vibration control. The rear suspension features aluminum-alloy uprights to reduce unsprung weight for improved response, while special trailing-arm mounting points reduce body squat during acceleration. For 2010, the Acura MDX uses stiffer rear trailing arm mounts, incorporates numerous body rigidity improvements and delivers reduced overall NVH.

As part of the Advance Package, the Active Damper System gives the 2010 Acura MDX an elevated level of handling precision designed to satisfy the most discriminating drivers - all while maintaining a smooth ride. The Acura MDX's Active Damper System features a new algorithm which provides two driver-selectable settings -Comfort and Sport -that tailor the suspension dampers for a more comfortable or more sporting ride. For 2010, the Active Dampers have been re-tuned for provide a more refined ride for Comfort mode and a more natural feeling Sport mode.

Using "active" Magneto-Rheological fluid dampers and predictive computer algorithms, the Acura MDX's Active Damper System can respond in as little as five milliseconds (0.005 sec.) to individually adjust the damping force of the shock absorbers ahead of actual body movements to provide improved transient handling, road isolation and body control.

The Comfort mode allows for a more relaxed driving experience by prioritizing road isolation and reduced passenger fatigue caused by road inputs, while the Sport mode prioritizes handling response and vehicle body control to allow for spirited driving with high levels of precision and vehicle composure.

For 2010, new (lighter) 18-inch diameter 5-spoke aluminum-alloy wheels are standard with 19-inch diameter 7-spoke aluminum-alloy wheels available as part of the Advance Package.
For excellent stopping power and control, the Acura MDX employs large 13.0-inch diameter ventilated front brake rotors and 13.2-inch solid rear brake rotors along with anti-lock brakes (ABS) with Electronic Brake Distribution (EBD) and Brake Assist.

Interior
For 2010, new attention to detail and added luxury further distinguish the Acura MDX interior. Expanded use of Milano premium leather to the available Technology Package, improved look and feel of interior trim materials, relocated front seat headrests for improved comfort, more detailed leather stitching (such as the Lancia-style stitching on the steering wheel and shift knob), thicker steering wheel grip, increased use of LED interior lighting and revised cockpit controls make it clear that the Acura MDX is focused on the driver - but not at the expense of passenger comfort.

The power driver seat adjusts 10 ways for optimum comfort, and the front passenger seat is 8-way power adjustable. The second-row outboard seats mirror the style and lateral support of the front seats, giving the interior a unique feel that highlights the Acura MDX's blend of sport and utility. Convenience and cargo features abound, including under-floor storage in the rear cargo area and a standard power-operated rear tailgate. There are multiple configurations of the Acura MDX's three rows of seating thus enabling a maximum useable cargo volume of 83.5 cubic feet. Additionally, a load flat floor is available when the second and third row seats are folded down.

Safety
In keeping with Acura's "Safety Through Innovation" initiative, the 2010 Acura MDX provides state-of-the-art safety for its passengers, including the application of Acura's Advanced Compatibility Engineering body structure.

ACE employs a network of front frame structures that work to absorb and more evenly distributes collision forces throughout the vehicle and also helps maintain the integrity of the passenger cabin in the event of a severe frontal collision. A special frame member located below the Acura MDX's front bumper is designed to engage the front bumper of a lower vehicle, allowing the bumper systems of both vehicles to attenuate crash energy more efficiently.

Inside the handsomely appointed Acura MDX interior, occupants will find advanced safety features including the latest generation of dual-stage, multiple-threshold airbags for the driver and front passenger.

There are also knee bolsters, front seatbelts with an automatic tensioning system with integrated load limiters, side airbags for the driver and front passenger along with side curtain airbags (with a rollover sensor) for all outboard occupants. Active front head restraints help reduce the likelihood of neck injury for front seat passengers and LATCH (Lower Anchors and Tethers for CHildren) mounting systems in the second row seating allow quick and secure installation of child seats.

The 2010 MDX is engineered to surpass the existing FMVSS 216 government roof crush test standard of 1.5 times the curb weight of the vehicle. However, the Acura MDX is so well engineered that it is anticipated to already meet the upcoming roof crush standard of 3.0 times curb weight. Efficient use of high-strength steel creates a body structure with the stiffness to allow such results while still permitting the use a large glass moonroof.

BMW 135i Coupe, 2010

BMW 135i Coupe, 2010




Starting immediately the BMW 135i Coupe come with a straight-six power unit of the latest generation for the first time combining BMW TwinPower Turbo Technology, High Precision Injection and fully variable VALVETRONIC valve management, all interacting with one another to set new standards for economy with the highest level of performance.

In conjunction with the seven-speed double-clutch gearbox (DKG) featuring Sport Automatic available as an option for the first time in the BMW 1-Series as of March 2010, these superior technologies offer a further significant reduction of fuel consumption and emissions on these top-flight performers, setting up new records in acceleration and dynamic performance.

The top engine featured in both versions of the BMW 1-Series develops maximum output of 225 kW/306 hp at 5,800 rpm from a capacity of three litres, combining spontaneous and direct response with unleashed free-revving driving qualities. Peak torque of the six-cylinder is 400 Newton-metres/295 lb-ft delivered from just 1,200 rpm all the way to 5,000 rpm.

The seven-speed double-clutch gearbox with Sport Automatic shifting gears without the slightest interruption in power and torque, is likewise designed and built for dynamic performance of the highest standard.

Sport Automatic offers not just the option to shift gears manually on the electronic gear selector lever or via the shift paddles on the steering wheel, but also the usual comfort and convenience of a BMW automatic transmission.

The combination of these two innovations in a compact car naturally guarantees driving pleasure of a new standard never seen before. Accelerating from 0 - 60 mph in just 5.0 and from 0 - 100 km/h in 5.2 seconds, the BMW 135i Coupe with its double-clutch gearbox offers the same supreme standard as a thoroughbred sports car even more than in the past.

A truly unique achievement in this performance class is average fuel consumption in the EU test cycle of 8.5 litres/100 kilometres (equal to provisional combined of approx. 22 mpg US), almost one litre/100 kilometres better than the comparable figure in the former model with its six-speed automatic transmission.

This significant reduction of fuel consumption, together with acceleration to 60 mph improved once again by 0.2 seconds, clearly confirms the progress made through BMW EfficientDynamics with this new engine and transmission technology.

The BMW 135i Convertible with double-clutch gearbox accelerates to 60 mph in 5.3 seconds and reaches 100 km/h in 5.5 seconds. Average fuel consumption in the EU test cycle is 8.6 litres/100 km (provisional combined US figure approx 22 mpg), which is 0.8 litres better than on the former model with automatic transmission.

On the same fuel consumption, this is better even than the acceleration and consumption figures of the respective models with a six-speed manual gearbox: the hand-shifted version of the BMW 135i Coupe accelerates to 60 mph in 5.1, the manual-gearbox version of the BMW 135i Convertible in 5.4 seconds (0 -100 km/h on the Coupe in 5.3, on the Convertible in 5.6 seconds).

At the same time the combination of the BMW TwinPower Turbo engine with the manual gearbox also newly developed likewise enhances all-round efficiency by a significant margin. In practice, this means a reduction of average fuel consumption by the BMW 135i Coupe to 8.5 litres and a reduction on the BMW 135i Convertible to 8.6 litres/100 kilometres (provisional combined US figure for both models approx. 22 mpg).

Outstanding innovation for optimised efficiency: first-ever VALVETRONIC on a turbocharged engine.

The turbocharger system following the twin-scroll principle separating the ducts for three cylinders at a time both in the exhaust gas manifold and in the turbocharger, as well as VALVETRONIC developed to an even higher standard of efficiency, contributes accordingly to the extremely spontaneous and direct response of the drivetrain.

This kind of technology allows infinite adjustment of valve stroke and valve timing on the intake valves. Throttle losses in the charge cycle are reduced to a minimum and the energy contained in the fuel is put to maximum use. In conjunction with High Precision Injection likewise optimised to an even higher standard, this offers an unparalleled balance of driving performance and fuel economy never seen before in this class.

The BMW 135i Coupe come as standard with a wide range of BMW EfficientDynamics technologies combined with one another in an appropriate symbiosis for each specific market, including features such as Brake Energy Regeneration, a gearshift point indicator on models with a manual gearbox, a map-controlled oil pump, final drive with optimised warm-up running qualities, as well as on-demand control of the engine's ancillary units such as the pressure-controlled fuel pump.

Enhanced dynamics, greater efficiency: new six-speed manual gearbox and optional seven-speed Double-Clutch Gearbox.

Both the BMW 135i Coupe come as standard with a newly developed six-speed manual gearbox. Optimised for maximum efficiency, this high-tech gearbox features dry sump lubrication significantly reducing drag forces and completely avoiding splash losses in the interest of even greater efficiency all round.

The seven-speed double-clutch gearbox with Sport Automatic featured for the first time in the BMW 1-Series makes an even greater contribution to the optimisation of driving characteristics in the spirit of BMW EfficientDynamics. The double-clutch gearbox improves both acceleration and the efficiency of these compact top-flight performers, at the same time combining this dual progress with the comfort features of a BMW automatic transmission. The seven-speed double-clutch gearbox shifts gears without the slightest interruption of power and torque and offers the driver the choice of either automatic transmission or a manual gearshift.

The fast and smooth shift of gears allows unusually harmonious acceleration and helps to reduce both fuel consumption and emissions. The close, sporting increments of the seven gears ensure that the optimum transmission ratio is always available in all situations.

A combination of dry sump and injection lubrication serves to further optimise the efficiency of the engine through a supreme level of oil supply.

Last but not least, the double-clutch gearbox is controlled with utmost convenience either through the newly designed gear selector lever or by gearshift paddles on the steering wheel.

The new six-cylinder with BMW TwinPower Turbo Technology and the seven-speed double-clutch gearbox bring out the unique character of these top performers in the compact segment even more and in greater style than ever before. Through their performance alone, the BMW 135i Coupe achieve the supreme standard of a very powerful sports car. And at the same time the driving experience conveyed by both models boasts the agility typical of a BMW 1-Series.

Superior drivetrain technology and a concept unique in this class with rear-wheel drive, the passenger cell moved far to the back, and almost ideal distribution of axle load, offer the optimum combination for unique driving pleasure.

Audi A1 e-tron Concept, 2010

Audi A1 e-tron Concept, 2010






The technology of the Audi A1 e-tron

The Audi A1 e-tron Concept now presents another approach - a compact electric car in the premium class. The four-passenger, two-door MCV city car was designed specifically for use in the metropolitan areas of Europe and North America and in the rapidly growing megacities of Asia and South America. The Audi A1 e-tron always drives on electric power; its internal combustion engine is only used to recharge the battery in isolated cases.

The integration of the new technologies shows the holistic approach that Audi is pursuing with electric mobility. The objective is to use the energy with the lowest possible losses. The precise interaction of the components, their intelligent packaging, and the efficient management of the current flows are the product of the expertise that the company has developed in this area.

Audi has developed a proprietary thermal management system to keep the battery, the electric motor, and the power electronics within their respective ideal temperature windows.

The electric motor: 75 kW (102 hp) peak power

The synchronous electric motor of the Audi A1 e-tron is mounted transversely at the front of the car. Its low mounting position has a positive effect on the vehicle's center of gravity. Continuous output is rated at 45 kW (61 hp), with peak power of 75 kW (102 hp) available in short bursts. 150 Nm (110.63 lb-ft) of torque is continuously available, and peak torque is 240 Nm (177.01 lb-ft).

The electric motor sends its power to the front wheels via a single-speed transmission. The elegant, retractable selector lever on the console of the center tunnel used to choose between "Drive," "Reverse," and "Neutral" was taken from the first Audi e-tron.

The power electronics are mounted in the engine compartment above the electric motor. The most important components are the pulse-controlled inverter, which serves as the controller between the electric motor and the battery; the DC converter, which connects the high-voltage network with the 14 volt electrical system; a breaker unit to protect the high-voltage components; and the charging module. The socket for the standard charging plug is located behind the rings in the single-frame grille of the Audi A1 e-tron. A fully depleted battery can be recharged in approximately three hours from the 380 volt grid. A display immediately adjacent to the plug-in connection shows the current charge status and the charging time remaining.

The concept of the innovative Mega City Vehicle requires the electrification of key auxiliaries. The refrigerant compressor of the climate control system, for example, is electrically powered by a high-voltage electric motor that supplies only the amount of power needed at the time.

This increases system efficiency substantially compared to conventional concepts. Thanks to a special circuit, the climate control loop also functions as a heat pump that regulates the temperature of the cabin and the battery.

The power steering of the Audi A1 e-tron is electro-mechanical and thus particularly energy-efficient. An electronic brake system makes it possible to tap into the recuperation potential of the electric motors. A hydraulic fixed-caliper brake is mounted on the front axle, with two novel electrically-actuated floating-caliper brakes mounted on the rear axle. These floating calipers are actuated not by any mechanical or hydraulic transfer elements, but rather by wire ("brake by wire"). In addition, this eliminates frictional losses due to residual slip when the brakes are not being applied. In addition, the servo unit received a new, demand-controlled electric vacuum pump.

The large electric motor powering the Audi A1 e-tron Concept can convert braking energy into electric current and feed it back into the electrical system. The high degree of recuperation benefits overall efficiency. The electric control actions are imperceptible to the driver, who notices only the familiar, precise, and perfectly controllable pedal feel.

The battery pack: a compact T arranged below the floor

The energy storage unit is arranged below the floor, where it is ideal for the center of gravity and weight distribution. The battery pack is shaped like a T, with the short "transverse beam" filling the rear section of the center tunnel and the "cross-beam" filling that area in front of the rear axle where the fuel tank is otherwise located. The 380 volt lithium-ion rechargeable battery has a nominal energy content of 12 kilowatt hours. It comprises 96 prismatic cells and weighs less than 150 kilograms (330.69 lb).

The Audi A1 e-tron can drive 50 kilometers (31.07 miles) emission-free in city traffic on the powerful battery. On longer trips, the battery is recharged by a particularly compact internal combustion engine mounted below the luggage compartment.

The range extender
The Audi A1 e-tron Concept car has a Wankel engine as a range extender, but other compact concepts are also possible. The small single-rotor Wankel has a chamber volume of 254 cc and runs at a constant 5,000 rpm in its peak efficiency window. The electronics also consider navigation data such as the destination and route profile to automatically activate the range extender as needed. The driver can also turn the range extender on and off as necessary with the push of a button The fuel tank holds 12 liters (3.17 US gallons).

The great strengths of the Wankel engine are the nearly vibration-free and quiet operation, the small dimensions, and the extremely low weight. Together with the generator, which is powered by the Wankel engine and produces 15 kW of electric power, the complete assembly weighs only around 70 kilograms (154.32 lb). This weight also includes the special power electronics, the intake, exhaust, and cooling unit, plus the insulation and the subframe.

The Audi A1 e-tron can also cover longer distances if the range extender charges the battery. The extra range, which is intended primarily for interurban driving, is 200 kilometers (124.27 miles).

According to the draft standard, the two different operating modes yield a fuel consumption of only 1.9 l/100 km (123.80 US mpg), which corresponds to CO2 emissions of 45 g/km (72.42 g/mile). In electric mode, there are zero local CO2 emissions - the compact Audi A1 e-tron Concept is thus ecological and economical.

The third impression that the Audi A1 e-tron Concept makes is that of a larger car. The compact two-door boasts all of the strengths of the new A1 model series - the carefully tuned, sporty chassis with specially designed 18 inch alloy wheels and 215/35 R18 tires; the generous, "grown-up" interior; the excellent fit and finish; and a multitude of high-end equipment.

Design
The concept car in Geneva has a special "Aqua Mint, pearl effect" paint finish; the contrasting roof arch is offset in "High Gloss Steel dark." As with the other two e-tron models, the 18-inch wheels with a 20-spoke turbine design convey the high-tech aspiration of the concept.

The rear diffuser with aluminum trim lacks tailpipes. This emphasizes the width of the vehicle and suggests the low emissions. The two front fenders are emblazoned with the "e-tron" logo.

The "Aqua Mint, pearl effect" exterior color carries over into the interior, where it adorns the door panels and the center console. The shift lever is a special leather-wrapped design; as is typical for the e-tron models, the start-stop button was placed in the front of the center console. A specially designed battery cover at the front of the car and the range extender engine with its cooling fins displayed under a sheet of glass in the luggage compartment also serve to visually underscore the clean technology of the Audi A1 e-tron Concept. And because an innovative drive concept also calls for innovative information management, the concept car features a freely programmable instrument cluster with a virtual display surface and innovative display and operating concept.
