Subaru unveils Hybrid Tourer Concept with boxer hybrid powerplant

(14/10/2009)

At the Tokyo Motor Show, which runs from 21 October to 8 November, Subaru will reveal its Hybrid Tourer Concept. The concept features a horizontally-opposed engine – in this instance the world’s first ‘boxer’ hybrid powerplant – and Symmetrical All-Wheel Drive (AWD). It marries these with an spacious cabin accessed through elongated gullwing-style doors, and an eye-catching, finely sculpted body.

The absence of B-pillars gives a heightened sense of light and space in the cabin, providing occupants with an unobstructed view of the outside world. The swept-back panoramic windscreen and a height-adjustable dashboard afford the driver a similarly unhindered vantage point.

At the front, a bold grille featuring Subaru’s now-trademark ‘wing’ motif sits in between a pair of modern headlights. The rakish, up-swept belt-line leads from the nose backwards to the chunky C-pillars, creating an air of purposefulness and understated aggression. Large 14-spoke alloy wheels fill the subtly flared arches.

Vitally important on any grand touring car is a refined and relaxing interior space and the Subaru Hybrid delivers exactly that. With ample room for four, occupants are cosseted in a stress-free, open environment. Even in the back, despite utilising an AWD system, the engineers still managed to create a flat floor, so rearmost occupants will enjoy an extremely comfortable journey.

The innovative hybrid system uses Symmetrical All-Wheel Drive and a 2.0-litre horizontally-opposed, direct-injection, turbocharged petrol ‘Boxer’ engine, allied to two electric motors – Subaru remains the only company to mate this engine layout to a hybrid drivetrain. The electric motors are powered by lithium-ion batteries – a 10kW item at the front and a 20kW unit at the rear.

In normal driving conditions the direct-injection petrol engine is used, but at lower speeds and start-up, the rear electric motor drives the car. The forward electric unit, which is mainly used as a power generator, kicks in to assist performance and efficiency while tackling inclines. Subaru’s in-house designed Lineartronic automatic transmission is featured, further boosting fuel efficiency and driving performance.

Paul Tunnicliffe, Managing Director of Subaru UK, said: “The Hybrid Tourer Concept perfectly demonstrates our commitment to environmentally-friendly innovation. This vehicle shows that our engineers are capable of developing something which is both technically advanced and stylistically enthralling, hinting at our future design direction.”

The Tokyo Motor Show will also see the debut of several other important concept vehicles. The Impreza WRX Carbon is based on the Japanese-market STI A-Line and features a distinctive carbon fibre roof. The five-speed automatic model offers a significant weight reduction and a lower centre of gravity, boosting the already impressive cornering performance. It boasts a luxurious full-suede interior, including a suede-wrapped dash.

A special show-edition of the Subaru Plug-in STELLA Electric Vehicle will also be on the stand. Although technically identical to the lithium-ion battery-powered, 40kW, 80km-per-charge EV showcased at last year’s G8 Summit in Hokkaido Toyako, the Tokyo Show STELLA has been re-styled by famous Japanese retailer, BEAMS, and now features striking decals.
