Seat Leon Ultra Green Concept Unveiled in Geneva
Boasting an all-new 1.6l TDI diesel engine which features common rail fueling, the Leon Ultra Green Concept delivers CO2 emissions of 99 g/km, just as the outgoing, smaller Ibiza Ecomotive. The combined fuel economy offered by the Ultra Green rates at 74.3 mpg (3.2l/100km), courtesy of the new 105 horsepower turbodiesel engine and the start/stop system, the first of its kind to be implemented on the Leon range.
A special readout on the dashboard keeps the driver up to speed with the system's operation, allowing him/her to chose the optimum gear for maximum economy at any given moment. By doing so, the Leon can save up to four miles per gallon.
Besides the start/stop system, Leon Ultra Green also uses a form of brake energy recovering system. It harnesses the energy generated during the braking process to save fuel by reducing the alternator's drain on engine power.
Lengthened gear ratios, the use of low rolling resistance tires and optimized aerodynamics that can been see on the concept originate from the existing Leon Ecomotive.
Leon Ultra Green comes as a follow up to the Leon Twin Drive Ecomotive hybrid prototype, presented in January to the Spanish government. At the time, the Spanish manufacturer said its prototype could be on the streets as soon as 2014. The Ultra Green however can be expected sooner, as the technologies it employs already exist in a viable form.
