The Subaru Levorg – the name is a combination of ‘Legacy’, ‘Revolution’ and ‘Touring’ – was unveiled today at the Tokyo Motor Show.

The Levorg, billed by Subaru more as a prototype than a concept, is expected to enter production early in 2014.

It’s powered by a choice of either a 1.6-litre direct-injection turbocharged ‘boxer’ engine developing 170PS, or a 2.0-litre with a more impressive 300PS and 400Nm at 2,000rpm.

Both are coupled to their symmetrical four-wheel drive systems via the company’s Lineartronic CVT transmission.

The 1.6 is the more efficiency-minded of the two, not surprisingly, and Subaru expect the production version to achieve 620 miles to a tank of fuel if kept at 62mph.  Average economy is expected to be around 49mpg, with the 2.0-litre unit returning around 37mpg.

The interior has been a particular area of focus for the company, not only with regards to maximising interior space and practicality, but also the use of quality materials and design.

The instruments, for instance, use a 3.5-inch colour display and twin dials with ice-blue illuminated rings.

The Levorg will also feature Subaru’s EyeSight system, which uses two cameras to assess the road ahead for obstacles or hazards, and can implement emergency braking or steering inputs to avoid a collision.

There’s no official word on whether the 2014 Levorg will come to the UK, but given its naming convention, we’d have to assume it forms the replacement for the current-generation Legacy models.
