|The Concept A|
Volkswagen has unveiled its new Concept A—a crossover between a sports car and an SUV—that uses a 100 kW (150 hp) implementation of its new 1.4-liter Twincharger (TSI) engine.
The Twincharger, introduced in August 2005, combines the low-end power boost provided by a mechanically-driven compressor (supercharging) with the higher-end increase provided by an exhaust turbocharger (turbocharging) to enable the downsizing of the engine for a given application while maintaining the driving experience for consumers. (Earlier post.)
VW first applied the TSI engine to the Golf, in which the 1.4-liter TSI delivers a torque corresponding to a 2.3-liter engine, but with 20% less fuel consumption. Compared to the 2.0-liter FSI engine in the Gulf, the power and torque gains are clear (+14% and +20%, respectively), although the decrease in fuel consumption is more modest (-5%).
Put another way, the Twincharger 1.4-liter TSI offers 36% more power than its FSI cousin of the same displacement: 90 kW vs 66 kW.
Volkswagen’s focus with the Concept A is more on the design of the car than the powerplant, however. The company notes:
A turbo diesel direct fuel injection (TDI) with diesel particle filter, the FSI Turbo of the Golf GTI (147 kW / 200 hp) and much more could also be used. Studies can do and are allowed anything.
The TSI engine in the Concept A is coupled with a six-speed transmission and 4MOTION all-wheel drive. The vehicle will have its first public showing at the upcoming Geneva auto show.
