Volkswagen of America, Inc. will debut a concept version of the latest SportWagen model featuring a 4MOTION all-wheel drive system and the new EA288 TDI Clean Diesel engine (earlier post) at the New York Auto Show. The concept previews the new Golf SportWagen that will go on sale in early 2015.

Based on the new MQB (modular transverse matrix) architecture, the Golf SportWagen will continue the trend introduced by the seventh generation Golf whereby it is lighter, bigger, roomier, more fuel efficient and more powerful than the outgoing SportWagen model. The new SportWagen will be offered with two powertrains:

  • A 170 hp (127 kW), 1.8-liter turbocharged and direct-injection four-cylinder TSI engine, mated to five-speed manual or six-speed automatic transmissions. These powertrains offer manufacturer highway fuel economy that’s improved by as much as 17% compared to the 2.5-liter Jetta SportWagen.

  • The new EA288 2.0-liter common-rail, turbocharged and direct-injection diesel engine that makes 150 hp (112 kW), an improvement of 10 hp over the current SportWagen model. The TDI model will have a choice of six-speed manual or DSG dual-clutch automatic transmissions.

Through the extensive use of high and ultra-high strength steels, the new SportWagen bodyshell is lighter than the current Jetta SportWagen and offers an enhanced crash structure. Throughout the car, optimized components—such as the seats, air conditioning unit, and electrical architecture—help to save weight.

The Golf SportWagen is 1.1 inches longer and 0.7 inches wider than the current SportWagen model. It is also 0.9 inches lower, which benefits both aerodynamic performance and the car’s proportions: the CdA number has been reduced by almost 10% compared with the previous generation.

The interior package has been optimized to give more rear-seat leg- and shoulder-room. Although the new SportWagen’s overall height was lowered by nearly an inch, front and rear headroom has been improved by 0.4 inches.

The new SportWagen also offers nearly 10% more cargo room with the rear seats folded than the outgoing model. Essentially, VW suggests, the Golf SportWagen provides a sportier alternative to compact SUVs.

Because it is based on the MQB architecture—which dictates a fixed relationship between the front wheel centerline and the pedals—the car’s proportions have changed. The front wheels, for example, are now 1.7 inches further forward than on the current SportWagen design. This has created what Klaus Bischoff (VW Brand Design) calls a cab-backward impression. “That’s what we call the proportions of premium-class vehicles, where the hood is long and the passenger compartment is a long way towards the back.

The new SportWagen features a new standard driver assistance system called the Automatic Post-Collision Braking System. This system automatically engages the vehicle’s brakes after it is involved in a collision in order to help reduce secondary collisions and to help bring the vehicle to a stop. The system is triggered when the airbag sensors detect a primary collision and it is limited to a maximum retardation rate of 0.6g by the Electronic Stability Control (ESC) unit.

The driver can effectively override the system at any time; for example, it is disabled if it recognizes that the driver is accelerating. The system is also deactivated if the driver initiates braking at a higher rate than 0.6g.
