Revealed at the recent 2013 Geneva Motor Show along with the Concept CA-MiEV, the GR-HEV adopts an all-new proprietary HEV solution, featuring a 2.5 liter Diesel engine and a front-mounted electric motor, mated to an automatic gearbox – all controlled by an electronic operating system.
This allows to achieve CO2 emissions below 149 g/km, despite the generous dimensions – the length is over 5.4 meters.
The design steers away from many current trends adopting a mix of curves and shapes that recall the trademark L200 key styling elements, namely the J-shaped rear door shut-line that visually separates the cab from the cargo bed.
While incorporating a number of modern and well-executed design elements, the final look appears to be quite busy and a bit overworked.
Below we report the official details on the design and the technology, along with a set of sketches and renderings.
From the official Press Release:
The show car was developed as a conceptual successor to a long line of one-tonne Mitsubishi Motors pickup trucks – from the original 1978 Mitsubishi L200.
Concept GR-HEV continues with this tradition adding a strong dose of aerodynamic chunkiness while escaping the square-rigged look that seems to prevail in the segment.
Over its long 5.42 m long dual-cab body, MMC Design produced a very muscular athletic shape, highlighted by a sharp blade-like character line, starting from the headlamps and progressing to form a very dynamic upswept beltline.
Carrying over a theme first developed for today’s L200, Concept GR-HEV offers a total (pick-up) look whereby the long load bed is the visual continuation of the passenger cabin, simply delimited by a graphic J-shutline, itself serving as support to integrated running boards.
Further rear, this load bed extends the 3D-sculptured shape of the cabin, whether in the wide open trapezoidal wheel arches (and their asymmetrical flat moulding, suggesting motion), in the shapely tailgate or in the helix-complex rear combination lamps.
With their “scattered diamond” LED design, they give an impression of precision-cut jewelry and premium quality appearance of the tail.
Topping it up, the upper structure is no less dramatic with a low roofline highlighted by twin elongated satin-finished side moldings.
Arching over the cabin, they extend to flying buttresses over the backlight, connected by a twin-boom aerofoil. As a clear statement of (tough) intent, the integrated bed cover intersects sharply all the curves.
At the front, the aerodynamic blades of the grille seem milled directly from solid brass as if to shield the Three-Diamond logo, in-between the sculptured wraparound diamond-shaped headlamps – an overall effect of width, stability and solidity.
Finishing touch, Concept GR-HEV rides on dynamically styled 3-spoke alloy road wheels using lightweight non-alloy spokes. Taking Mitsubishi’s Three-Diamond corporate emblem as the design theme, they suggest strength.
Simpler and more affordable than either EV and PHEV, HEV is deemed best suited to the heavy-duty daily requirements of pickup truck users and a perfect vector for MMC’s green ambitions all the way to the most remote corners of the planet with an ambitious target for CO2 emissions below 149 g/km – far better than segment average.
The battery pack located (and protected) within the ladder frame – with further protection being provided by cross guard bars.
Beyond this specific one-ton pickup application, the addition of an electric motor to a Diesel engine brings further benefits:
• Instant response from the electric motor boosts Diesel engine accelerations.
• The motor also increases high-end torque of the Diesel engine.
• Quieter accelerations and high-speed cruising (within legal limits).
• Cleaner Diesel emissions.
This combination can also provide pure electric power on demand with available AC supply (100V～240V), to replace a generator or to allow the use of a 100V winch for instance, as well as the ability to drive over short distances in pure-electric mode.
Concept GR-HEV also uses Mitsubishi’s renowned full-time 4WD technology, featuring Super All Wheel Control (S-AWC) integrated vehicle dynamics control system to deliver high stability traction and driving performance under all road conditions.
