Subaru announced the Levorg concept will make its world premiere at the 43rd Tokyo Motor Show on Wednesday Nov. 20 and hints at improvements to come for Subaru’s presently weak hybrid offerings.

The Levorg will feature an all-new 1.6-liter horizontally-opposed Boxer engine with direct injection turbo (DIT) technology. This Subaru-developed engine is designed to offer smooth performance and greater environmental efficiency.

The new engine will also be on show on the Subaru motor show stand as a technology exhibit.

According to Subaru, the Levorg concept hints at a new vehicle currently under development for market launch in Japan in 2014.

Subaru explained the name “Levorg” comes from a combination of the words “Legacy,” “Revolution” and “Touring,” and the concept will blend the practicality of a tourer and the stylish design and feel of a sports car.

It is believed the new Boxer engine to be revealed, or a derivative of it, could eventually be found as part of the next generation of the brand’s hybrid powertrain.

Subaru’s first hybrid was launched recently, known as the XV Crosstrek Hybrid – a nice car but whose mpg scores do not rise significantly above the conventional version upon which it’s based.

The Levorg sports tourer prototype will be joined on the Subaru show stand by another new concept vehicle called the Crossover 7 concept, a seven-seat SUV designed to combine the rigors of urban family use with true off-road driving capability.
