Lexus Planning Four-Cylinder GS Hybrid?

Lexus GS 450h

Lexus GS deputy chief engineer Koji Sato recently spoke with Auto Express, and shared some welcome information that a “small hybrid” engine for the GS is in the works:

Although there are no details on the new powerplant, it is likely to sit at the entry point to the range and is likely to be a four-cylinder petrol engine allied to an electric motor. Combined power output should be around 180bhp.

Sato said the engine would have to boast fuel economy and CO2 emissions on a par with the BMW 520d, so expect the model to emit around 120g/km of CO2 and return around 50mpg.

A decision is ‘imminent’ said Sato on the exact specification of the new hybrid engine, with an announcement expected ahead of the GS’ launch in the UK next summer.

From the numbers, I would assume the new Camry Hybrid engine (200bhp & 52 “British” mpg) is the unspoken powerplant — but regardless of engine details, a four-cylinder hybrid GS would be huge news for the European market, allowing Lexus to build on the success of the CT 200h, and in turn, create some real momentum for the brand moving forward.

One other detail to note from the Auto Express article:

In related news, Sato also said there was a strong desire within Lexus to produce a high performance BMW M5-rivalling GS F model, following in the footsteps of the IS F. “The GS has an all-new chassis with wider tracks, double wishbones at the front and a mulit-link rear set-up. It would make a very good base for a performance car,” he added, although admitted that there are no official plans for one just yet.

At this point, there has to be a “wait & see” approach with a possible GS F — so much will depend on how well the new GS sells.
