Efficient TSI twin-turbo engine
Under the bonnet of this exciting prototype lies a powerful and economical 1.4 twin-turbo engine with TSI technology, which is partnered with a seven-speed DSG gearbox. This marks a first for SEAT, which has never before produced a model combining the 1.4 TSI twin-turbo engine and the seven-speed DSG gearbox with steering wheel paddles.
Coupling this highly efficient 1.4 TSI twin-turbo power unit to the speed and sportiness of the DSG transmission promises a thoroughly enjoyable drive for enthusiast and everyday motorist alike. Add to this the option of operating the gearshift by means of the paddles on the steering wheel and the sublime stability and precision of SEAT’s signature ‘Agile Chassis’, and drivers are able to enjoy sporty motoring at its very finest.
The 1.4 TSI twin-turbo unit in the ‘SportCoupé’ also promises modest CO2 emissions thanks to its small displacement. Thus the ‘Bocanegra’ upholds the brand’s pledge to reduce CO2 emissions of all its engine variants. Clearly, this promise is already being delivered with the launch of ECOMOTIVE versions of the Ibiza and León.
