Fuel cells will also play a role in the brand's electrification strategy.

Lexus won't follow its German rivals into the world of plug-in hybrid luxury sedans. Instead, its electrification strategy will focus on full electric cars and fuel cell-powered models.

"We do not need to have plug-in hybrid vehicles. It's a loophole in the market. We will reach the CO2 targets without them," said Alain Uyttenhoven, the head of Lexus' European boss, in an interview with British magazine Auto Express.

Zero emissions -- which renders the radiator grille all but useless -- will come from the top down. Lexus will begin its offensive by introducing either an electric or a hydrogen-powered luxury model by 2020. It will be based on either the LS or the LC, according to Auto Express. The publication explains the cost of fitting either of those drivetrains to a smaller model (like the CT) is be too high right now.

The technology will trickle down from the top sooner or later, though. Lexus could be eyeing a small, city-friendly model powered by an all-electric drivetrain. If launched, it would be aimed directly at the electric variant of the MINI Cooper that will hit the market in the coming years. Don't expect it to be cheap, but Lexus says that's not necessarily a bad thing.

"A lot of people who have reached a certain level of wealth like to have a small, premium car more than a bigger, more mainstream brand of car," Uyttenhoven said.
