Volkswagen – The new W12 and other innovations at the Motor Symposium – Quattroruote

Presenting the Motor Symposium 2015 Vienna the new units to be introduced on future production models, the Volkswagen Group talks about the future of the internal combustion engines boundless view the range of products offered on the market, no wonder the combination in a single press release of TDI of the latest generation for light commercial vehicles and the renewal of the mighty W12 TSI, united by a common technological developments to reduce emissions and consumption without sacrificing performance.

Room for improvement. Direct injection, friction reduction and integration of electrical systems such as e-booster, according to German technicians allow still large room for development, but It will also be essential systems management cooling and processing of components with a new laser treatment, which will be extended to mass production soon. For example, these combined interventions to higher speeds, the unit allows TDI already today to reach an output of over 100 kW / liter, while the petrol engine was presented a prototype derived from the three-cylinder 1.0 liter TSI: thanks e-booster and solutions derived from the Polo WRC racing, this engine is capable of delivering 272 hp and 270 Nm of torque.

The new W12 TSI . Dedicated to premium models of the Volkswagen Group, it comes after an evolution lasted 13 years. In this new version offers the dual injection system directly and indirectly, a new processing of the barrels, the cooling system with variable flow rate and an unprecedented oil circuit with separate pumps for use in off-road, the primary clue debut this unit on the Bentley Bentayga . The engine is fitted with cylinder deactivation at partial loads, the Start & amp; Stop and hydraulic engine mounts to reduce vibration active, while supercharging is obtained with two twin-scroll turbine. The six-liter updated so produces an output of 608 hp and 900 Nm of torque available between 1,500 and 4,500 rpm and CO2 emissions below 250 g / km.

Light commercial

vehicles. for this segment it was presented the new 2.0 TDI 4V Euro 6, which premiered on the new generation of the Multivan and Transporter models. Faced with a reduction in the average consumption of 14% has been improved torque delivery, thanks to the common-rail system with 2,000 bar, the new EGR valve and the intake manifold with variable flow. The approval Euro 6 has requested the use of the SCR system for the treatment of exhaust gases. The new units will be offered with a power range from 84 to 204 hp and torque of 220 Nm and 450: with over 76 kW and 225 Nm of torque per liter, the figure improved by 13% the performance of the previous generation. The most powerful version can count on the twin turbocharging with variable geometry.
