Buick LaCrosse promises 37 Mpg on the highway

The Buick customers will be offered a four-cylinder LaCrosse sedan incorporating eAssist micro-hybrid technology as standard, beginning with the summer of this year. Its fuel economy is rated to 37 mpg on the highway and 25 mpg in the city, according to EPA certification, due to the fact that LaCrosse makes use of a variety of systems and body modifications. The regenerative braking is ensured each time the throttle pedal is released by the eAssist system which incorporates a 115V lithium-ion battery and a 15 kW electric generator/motor and it is connected to a six-speed automatic transmission and a 182HP 2.4-liter ECOTEC direct injection four-cylinder engine. Fuel is thus saved by all the electrical systems of the car which are produced by the electricity and the system also provides up to 15HP of power assistance in various driving conditions through the battery. Steve Poulos, global chief engineer of the eAssist system stated that LaCrosses's gear ratio was lowered by the additional 15HP produced by the electric assist, without affecting in a way or another performance and reserve acceleration. A good example for this matter would be when climbing the grade of an overpass, the LaCrosse with eAssist system maintains gear for increased efficiency and improved performance, unlike a normal vehicle which would be downshifting and, implicitly, losing some fuel efficiency. Cutting fuel delivery in certain deceleration conditions, the engine shut-off mode is another important and efficient function of the eAssist system. Increased aerodynamic efficiency through the electronically controlled shutters in the lower grille that close at higher speeds to push more air over the car, together with low-resistance tyres and improved underbody aerodynamics, represent other features of the LaCrosse with EAssist. Eco-driving is motivated by the car's instrument panel which comprises an Eco-gauge that shows the driver how to attain maximum efficiency.
