Toyota engineers are working intensively on the development of a new engine that could become more popular than the powerful 2JZ straight six. It is an engine that will power Toyota and Lexus cars.

The new engine is part of a family of 1.5- and 2.0-liter inline-four engines, each of which will be optimized for hybrid or plug-in hybrid assistance and compatible with alternative fuels, which could give them a chance to live long after of traditional internal combustion engines that are disappearing due to restrictions. In addition to the 400 hp four-cylinder engine, a 300 hp version will also be available, meaning Toyota will have a great choice of powertrains ready for the upcoming MR2 and Celica models.

Also, a Lexus RC coupe powered by this 600 hp (441 kW) engine, mated to a 6-speed manual transmission, is currently being tested. Although Lexus has not released any information about this car, the first information came from a Japanese journalist, who had the opportunity to see the IS sedan equipped with a version of the same engine, but with 400 hp (294 kW) and an eight-speed automatic transmission.

Engineers claim it’s only a motorsport project, but it seems possible that Lexus could fit the new engine into the production coupe. Whether a manual gearbox will also be installed in the new cars remains to be seen, as Lexus is not known for such gearboxes. However, a simulated manual transmission system for electric cars has been tested, so perhaps there is hope.
