SEAT Leon Ecomotive Concept

The Leon Ecomotive Concept is a sign of the progression of efforts being taken to improve vehicle emissions and fuel consumption. The Leon Ecomotive Concept premieres in Geneva Motor Show 2009 with a number of novelties over the Spanish firm's outgoing Leon, Ibiza and Alhambra Ecomotive variants.

Beginning with the new 105 hp 1.6-litre TDI engine, featuring a DPF particulate filter and common rail technology, emissions and consumption are greatly improved. Some 20 g/km of CO2 has been wiped off the charts by introducing a new Auto Start/Stop system, regenerative braking as well as the new common rail diesel powerplant.

SEAT'S ULTRA-GREEN LEON ECOMOTIVE CONCEPT

  • CO 2 emissions slashed to just 99 g/km
  • Refined, efficient 105 PS 1.6-litre TDI common rail engine
  • First application of Auto Start/Stop and brake energy regeneration technology

SEAT is once again grabbing the spotlight at Geneva with the unveiling, today, of an exciting new concept car.

The Swiss debut of the Leon Ecomotive Concept, a dramatic development of the existing low emissions, high economy family five-door, underlines SEAT's growing stature as a motor maker that appeals across the spectrum – from exceptional economy to outstanding performance.

Boasting a raft of new technologies, as well as an all-new 1.6-litre TDI diesel engine which features state-of-the-art common rail fuelling, the Leon Ecomotive Concept delivers class-leading CO 2 emissions of just 99 g/km – the same as the outgoing and much smaller Ibiza Ecomotive – while offering combined fuel economy of 74.3 mpg.

These significant improvements in both emissions and economy over the current Leon Ecomotive (119 g/km and 62.8 mpg combined) come courtesy not just of that new 105 PS turbodiesel engine, complete with DPF particulate filter, but also an array of clever fuel-saving innovations.

Among the new features debuting on the Leon is an Auto Start/Stop function.  When the car comes to a halt – for instance at a traffic light – and the driver selects neutral and takes his foot off the clutch, the Start/Stop function automatically switches off the engine.  As he prepares to move off again and depresses the clutch, the engine is re-started and the car can be driven as normal.

The driver's kept up to speed on the system's operation via a special readout in the instrument binnacle, which also shows the optimum gear for maximum economy at any given moment.

This development alone can deliver fuel savings of as much as four miles per gallon around town, without the need for the Leon 's driver to make any changes to their driving style.

As well as the slick Start/Stop system, the car being unveiled at Geneva also includes a form of brake energy recovery – harnessing energy generated during the braking process to save fuel by reducing the usual drain on engine power that stems from a conventional alternator.     

Of course many of the existing fuel- and emissions-saving techniques employed in the existing Leon Ecomotive find their way into the new concept car: lengthened gear ratios, the use of low rolling resistance tyres and optimised aerodynamics all feature.

The new Concept naturally includes the same elegant design revisions as those seen across the revised Leon and Altea family range, also making their debut in Geneva .

Top quality interior design and trim are matched by generous equipment that includes ESP, ABS and TCS, numerous airbags, body-coloured electric door mirrors, air conditioning and a six-speaker MP3-compatible CD radio with Aux-in connection.

The Leon Ecomotive Concept follows hot on the heels of the recently-unveiled Leon Twin Drive Ecomotive prototype which made its debut at the SEAT Technical Centre in Martorell, near Barcelona , in January.

That concept showcases SEAT's work towards producing vehicles which run on electricity in urban areas, switching seamlessly to conventional petrol or diesel power for longer trips out of town.
