New Details on 2014 Lexus IS 300h Engine

Kevin December 31st, 2012

2014 Lexus IS 300h

On December 25th in Japan, the all-new Toyota Crown was introduced with the 2.5L hybrid engine that’s expected to power the 2014 Lexus IS 300h.

Going from the press release, this new rear-wheel-drive hybrid system brings D-4S technology together with a 2.5-liter, four-cylinder inline Atkinson cycle engine and high-torque electric motor — all together, it produces 217 total system horsepower and 163 lb-ft of torque while delivering fuel economy of 54.8 mpg (4.29L/100km) and a CO2 of 100 g/km.

(As it stands, only European & Asian markets will be offering the first-ever IS hybrid — the Lexus IS 300h will not be available in North America.)

For full specifications, check out the chart after the jump.
