VW Golf R Touch Concept arrives at 2015 Consumer Electronics Show (CES)

Volkswagen introduced at the 2015 Consumer Electronics Show (CES) the Golf R Touch, a concept vehicle that features an infotainment system which incorporates gesture control. According to the German manufacturer the gesture control is the next step in the area of intuitive control and all you need is a hand movement in the space in front of the infotainment system in order to make human and machine interact as one.

What’s more interesting is that almost all the controls were implemented via touchscreens and sensor switches.

Moreover, the Golf R Touch Concept was equipped with three displays: a 12.8-inch high-resolution infotainment system touchscreen, a Control Center consisting of an 8.0-inch display with touch feedback arranged beneath it to control vehicle, climate control and media functions, as well as an Active Information Display (digitalized instruments, 12.3-inch).

According to the official press release, the layouts of the central touchscreen and the Active Info Display can also be customized, just like a smartphone or tablet.

Just like any other 2015 VW Golf R, the Golf R Touch Concept uses the same 2.0-liter direct-injection EA888 TSI engine producing 292 hp and 280 lb-ft (380 Nm) of torque.

Mated to a six-speed DSG dual-clutch automatic transmission, the Golf R accelerates from 0 to 62 mph (96 km/h) in 4.9 seconds, with a top speed limited to 155 mph or 250 km/h.

The Volkswagen Golf R has always been an all-wheel drive car employing the permanent 4MOTION system. The fourth generation of the Golf R features the latest-generation 4MOTION system as coupled to a six-speed transmission with a reinforced clutch and short-travel shifting. This 4MOTION system could optionally be mated to a six-speed dual-clutch gearbox (DSG) with both automatic and manual shifting.

Featuring enhancements like the Haldex 5 coupling, the 4MOTION all-wheel drive system in the VW Golf R activates before any wheel starts to slip, thereby getting rid of nearly all traction losses. This is achieved by employing an advanced control function based on certain driving conditions.

During coasting or during a low-load operation, the rear axle is decoupled and the front axle takes care of forward propulsion, consuming less fuel in the process. When needed, the rear axle of the Golf R can be variably engaged in fractions of a second, thanks to the Haldex coupling that is activated by an electro-hydraulic oil pump.

The system features a control unit that continually calculates the ideal drive torque for the rear axle. By activating the oil pump, the unit also controls how much the multi-plate clutch should be closed. In direct proportion to the desired levels of torque at the rear axle, the contact pressure at the clutch plates is increased by the oil pressure.

This way, the amount of pressure applied to the clutch plates can be employed to continuously vary the amount of the transmitted torque. Since the control unit regulates the torque distribution as a function of dynamic axle loads, it could prevent wheels of the VW Golf R from spinning when driving off and accelerating.

Meanwhile, the Haldex 5 coupling is activated according to the engine torque needed by the driver. The all-wheel drive control unit features a driving status identification system that assesses parameters like wheel speeds and steering angle. Thanks to this, up to nearly 100 percent of drive torque can be directed to the rear axle, when needed.
