It’s funny how you can sometimes overlook a real gem in the motoring world. One such gem that’s passed me by until today is the Volvo C30 Polestar, a hardcore 400bhp version of Volvo’s handsome but typically underwhelming sports hatch.

The Polestar, officially a one-off concept, isn’t your average warmed up range topper mind. It’s had a complete engineering makeover from Polestar, the tuning firm behind Volvo’s Swedish Touring Car Championship effort.

So it gets a turbocharged 2.5-litre five-cylinder engine (also found in the Ford Focus RS), a Haldex all-wheel drive system, a pair of clever differentials, brakes borrowed from a Ferrari F430, downforce-producing aerodynamics and a full-on race suspension system.

I was a passenger in the Polestar in this afternoon’s Supercar Run at Goodwood, with race-winning Swedish touring car driver Alexander Storckenfeldt as my pilot. Thoughts? Well, in the real world, this is almost as quick a car as you’ll ever need.

Performance is explosive off the line (0-62mph takes just 4.6sec) and the Haldex and suspension systems helps get the power down with minimum fuss, very little wheelspin and almost no torque steer. Through the corners, it was nicely balanced and on its cut slick tyres had grip to spare.

Storckenfeld - and his capable and brave right foot – loved it and was at a loss as to why Volvo isn’t making the car in a limited production run.

And I’m with him, too. If the firm wants to ditch its old fashioned ‘Project Volvo’ image once and for all, what better way than by creating legalised lunacy with a real benchmark performance icon?

I’ve heard murmurings of a limited run of 500 commanding a £50,000 price tag each. By putting this into production, Volvo has nothing to lose and everything to gain. Fingers crossed there’ll be a production version to sample at Goodwood next year.
