Daihatsu showed an exciting new concept car at the
Frankfurt Motor Show last week, the Hybrid Vehicle Sports (or HVS for short). The exterior and interior of the HVS don't give much away, looking like it would be a suitably upmarket replacement for the little
Copen (itself given a revamp at the show), replacing that car's cute looks with sharper creases and a more universal sporty appearance. The interior has a little concept gloss, but the basic shape looks ready for production, and it looks like a good competitor to the likes of Mazda's new MX-5.
The interesting bits are hidden away at Frankfurt though. Under that shapely body is a new hybrid drive system, aimed at not only reducing fuel consumption and emissions, but also enhancing the driving experience. Under the bonnet lies the new 1.5-litre four-cylinder engine as shown in the Daihatsu D-Compact, with 103bhp. However, it is in series with two permanent magnetic synchronous electric motors at the front (adding another 50bhp) and another motor at the rear. The rear end features an innovative layout allowing drive to be apportioned to the rear wheels individually according to grip levels and cornering speeds, effectively acting as an electronic differential. This drivetrain is a long way from production yet, but the HVS may appear as a conventional sportscar in the next couple of years.
