Revealed at the Qatar Motor Show in 2011, the VW XL1 not only looks amazingly futuristic but also features a whole raft of pioneering construction and drivetrain technology. Power comes from a meagre 800cc TDI two-cylinder common-rail diesel engine which develops just 48bhp. It's linked to an electric motor producing a further 27bhp, resulting in a far more respectable 75bhp when working together. Bearing in mind the kerb weight is just 795kg, that's adequate to scoot it along, quite nicely we presume, as you go through the 7-speed DSG gearbox fitted to the car. It will even run just on the electric motor with zero emissions - and in this mode, it has a range of 50km (31 miles). That's more than enough to get you to your local supermarket for the weekly shop.

The XL1's suitably streamlined body is equally innovative. It's made from Volkswagen's patented carbon fibre reinforced polymer (CFRP) which is constructed using a process called resin transfer moulding (RTM). Elsewhere, magnesium wheels, ceramic brake discs and the use of aluminium for the dampers, steering and brake callipers help shave off that all important weight. In fact, just 23.2% of the car is made out of either steel or iron. Meanwhile, friction-optimised wheel bearings and driveshafts, as well as special low-rolling resistance Michelin tyres, contribute to the low energy consumption and this technologically advanced masterpiece was made at VW's Osnabrück factory.

Fundamentally, the XL1 is a two-seater with gullwing doors and shrouded rear wheels being the key design features helping to keep the coefficient of drag to a minimum. That's not to mention the natty use of small cameras (e-mirrors) instead of traditional wing mirrors to tell the driver what's going on outside. Remember Audi being boastful of its ground-breaking 100 model's 0.30 drag coefficient back in the early 1980s? Well, the VW XL1 virtually halves that with its figure of 0.186, making it the world's most aerodynamic road-going production car to date.

Having covered just 312 miles, the example we have on offer is you could say in 'as new' condition. The Clearwater Blue Metallic paintwork is flawless as are the Black Alcantara seats and ceramic black interior finishes. Single ownership from new, to be offered including the well-suited registration number of 'VW15 XLL'. A super addition to any car collection or enjoy turning heads while achieving 300+MPG on the commute to work.
