Volkswagen Passat Bluemotion® Concept makes Global Debut at 2014 North American International Auto Show
Engine is world’s first inline four cylinder with cylinder deactivation
The VW Passat Bluemotion® Concept comes with Class leading* estimated highway fuel economy rating of 42 mpg.
Chattanooga/Detroit -- The Passat BlueMotion® Concept that is being presented by Volkswagen of America at the 2014 North American International Auto Show in Detroit shows just how fuel-efficient a non-hybrid, gasoline-engined mid-size sedan can be. Based on the current Passat that was developed specifically for North America, the BlueMotion label defines the version that has the best efficiency in the model lineup. In this case, the Passat BlueMotion Concept has a manufacturer estimated highway fuel economy of 42 mpg, best in class among non-hybrid, gasoline-engined mid-size sedans.
The Passat BlueMotion Concept features an all-new version of the Volkswagen 1.4-liter EA211 TSI® engine with direct injection and turbocharging. On top, this Passat also offers Active Cylinder Management (ACT) technology, previously seen on the European Volkswagen Polo and Golf models. ACT deactivates the valvetrain on cylinders two and three for situations when the driver only applies light throttle pressure to maintain specific city speeds. This is the world’s first inline four-cylinder engine with cylinder deactivation.
Another Volkswagen innovation that helps save gas is the coasting function, used also on the Jetta Hybrid. As soon as the driver releases the accelerator pedal, the DSG® transmission decouples the engine, allowing the Passat to roll with the lowest possible mechanical drag from the other moving components.
Additional fuel savings come from the stop/start system, which shuts off the engine when the car comes to a temporary stop. As soon as the driver lifts their foot off the brake, the 1.4-liter four-cylinder engine starts again. All these measures result in a manufacturer estimated highway fuel economy rating of 42 mpg. The Passat BlueMotion Concept also delivers 150 horsepower and 184 lb-ft of torque.
The Concept’s striking Reef Blue Metallic color will be introduced on other Passat models, too. The interior of the Concept also offers two-tone seats that carry blue dividing lines between the darker and lighter leather seating surfaces. The stitching indicates this is a member of the BlueMotion family, which has been rolled out globally since 2006 on many highly fuel-efficient Volkswagen models.
New Volkswagen Golf R makes its U.S. Debut at 2014 North American International Auto Show
The North American International Auto Show will see the U.S. debut of the latest Golf R, the most powerful version of the Golf ever to be sold in this market. With an estimated 290 horsepower, the new Golf R has 34 hp more than the previous version, which was sold as a 2013 model. Despite the additional horsepower, the new R model is expected to be considerably more fuel-efficient than its predecessor: on the European cycle, the car gets a combined figure of 33 mpg with the six-speed manual transmission, up from 28 mpg.
Like all three previous Golf R models, the new model transfers its turbocharged power to the road via a permanent all-wheel-drive system; in this case, the latest version of the 4MOTION® system with a fifth-generation Haldex® coupling. To ensure great chassis dynamics, there’s a new sport suspension, the “progressive” variable-ratio steering system, and a stability control system ("ESC Sport") which can now be deactivated for track driving. Other highlights include the optional DCC dynamic chassis control system.
Equipped with a six-speed manual transmission, the Golf R will reach 62 mph from rest in 5.3 seconds, an improvement of 0.4 seconds over the old car; with the six-speed DSG® dual-clutch automatic transmission, the car completes the sprint in just 4.9 seconds.
The new Golf R is equipped with an extensive package of exclusive features. Along with specially designed bumpers, side skirts, and 18-inch aluminum-alloy wheels, the Golf R can also be visually distinguished from the GTI by details such as standard Bi-Xenon headlights with newly designed LED daytime running lights (in a dual-U design) and a two-branch exhaust system with four chrome tips. Inside, the Golf R underlines its position as the flagship of the model range with sport seats with leather seating surfaces, a leather-wrapped three-spoke sport steering wheel, ambient lighting, and R-specific instrumentation. The most powerful and fuel-efficient Golf R will be launched in the U.S. in the first quarter of 2015 in four-door form only.
High-tech turbocharged engine
The Golf R has an even more advanced version of the EA888 four-cylinder turbocharged and direct-injection TSI® 2.0-liter engine that’s fitted to the new Golf GTI. The engineers boosted power to an estimated 290 hp, delivered at 5500 rpm, thus creating one of the most powerful four-cylinder production engines in the world. Maximum torque has been increased to 280 pound-feet, available over a broad speed band from 1800 to 5500 rpm. To attain this output, the Golf R model’s 1984-cc engine was subjected to a motorsports-style development program. The following components were modified or completely redesigned compared to the GTI engine: the cylinder head (together with exhaust valves, valve seats, and springs), pistons, high-pressure injection system, and turbocharger.
The Golf R model’s EA888 series engine has innovative engineering solutions such as water-cooled exhaust gas channels running through the cylinder head to the turbocharger (to help efficiently reduce full-load fuel consumption) and a dual injection system with direct and multi-port injection. Thanks to its new fully-electronic coolant control system, the Golf R TSI engine has much more efficient thermal management with a reduced warm-up phase that reduces frictional losses and fuel consumption. In addition, the TSI engine has variable valve timing on the intake and exhaust sides, as well as two-stage exhaust-valve lift. This helps enable optimal control of the charge exchange process for better performance, fuel economy, and lower emissions.
4MOTION all-wheel-drive system
The Golf R has always used 4MOTION permanent all-wheel drive. Using refinements such as the Haldex 5 coupling, the latest-generation 4MOTION system is activated before any wheelspin occurs, helping eliminate nearly all traction losses. The system achieves this by using an advanced control function based on specific driving conditions. When operating under a relatively low load or when coasting, the front wheels are driven and the rear wheels are decoupled, helping to save fuel. However, the rear wheels can be engaged in fractions of a second whenever necessary via the Haldex coupling, which is activated by an electro-hydraulic oil pump.
A control unit continually calculates the ideal drive torque for the rear wheels and controls how much the multi-plate clutch should be closed by activating the oil pump. The oil pressure increases the contact pressure at the clutch plates in proportion to the torque desired at the rear axle. So, the amount of pressure applied to the clutch plates can be used to continuously vary the amount of torque going between the front and rear wheels. If necessary, nearly 100 per cent of the drive torque can be directed to the rear wheels.
In addition to the Haldex coupling that acts longitudinally, four electronic differential locks (EDS) that are a function of the electronic stability control system act laterally. The system briefly brakes a wheel that is slipping, enabling uninterrupted and stable transfer of drive power to the wheel on the opposite side.
In addition, the Golf R is equipped with the XDS® cross differential lock at the front and rear. The latest version, known as XDS+, applies this functionality to a larger range of dynamic performance, helping make the vehicle more agile. When the car is being driven at highway speeds, brake pressure is applied to the inside wheel to help restore optimal traction as soon as the electronics detect excessively light loads. XDS+ thereby operates like a limited-slip differential and thus compensates for understeer during faster cornering.
The new Golf R is equipped with "ESC Sport" as standard. The system is activated by a two-stage switch on the center console. When the driver presses this switch briefly, Electronic Stability Control (ESC) switches to the "ESC Sport" mode. In very fast driving on a race track, the ESC system has a higher threshold in this mode. When the ESC button is pressed for longer than three seconds, the system is fully deactivated for high-performance track driving, a feature that is available only on the Golf R.
