Lotus and Proton increase the fuel efficiency of the Proton Gen-2 by 28% while decreasing C02 emissions by 22%
The company, which builds the lightweight Elise and Exige aluminum sports cars, has in the past worked in conjunction with Tesla Motors to develop the all-electric Tesla Roadster. The Tesla Roadster is loosely based on the Lotus Elise roadster and manages to bolt from 0 to 60 in 4 seconds flat and tops out at 130 MPH. Thanks to its generous battery pack, the Tesla Roadster can travel 250 miles on a charge.
Lotus Engineering and its parent-company, Proton, are taking their engineering expertise to the next level with a new hybrid-electric sedan technology demonstrator. At this year’s Geneva Auto Show, the Lotus EVE Hybrid (Efficient, Viable, Environmental) was unveiled to the world.
Lotus took a Proton Gen-2 and paired it with a full parallel electric hybrid drive system. The 1.6 liter gasoline engine works in conjunction with a 30kw motor, 144V NiMH battery pack and a continuously variable transmission (CVT).
Using the hybrid powertrain, Lotus was able to cut the CO2 emissions of the Proton Gen-2 from 172g/km to 134g/km. Combined city/highway fuel economy also rose from 39.2 MPG to 50.2 MPG. When operating in full hybrid mode, the EVE Hybrid generates 141 HP, can travel 0 to 60 in 9 seconds and tops out at 118 MPH.
