Koenigsegg can take the P1, LaFerrari & Huayra with the Agera R

Koenigsegg believe that the Agera R has more than the measure of the new toys at Geneva – LaFerrari and McLaren P1 – and Pagani’s Huayra lap at Top Gear was a farce. But a car that was also at Geneva was the Koenigsegg Hundra, Koenigsegg’s one-off special to celebrate 100 Koenigseggs built since Christian von Koenigsegg started bolted his immense supercars together in a shed in Sweden a decade ago. So we thought it would be interesting to chat to Koenigsegg people – including Koenigsegg’s UK dealer Supervettura –  and get their thoughts on the new batch of supercars that could perhaps take some gloss off the offerings from Koenigsegg.

Volkswagen XL1

This, remarkably, is the production version of the Volkswagen XL1, the most fuel-efficient production car in the world, a car we'll see in Geneva in a little over a week. Barely changed from the concept version shown at the Qatar motor show two years ago, the production XL1 is the first production result of VW's 1-liter project – to design a car that uses less than 1l/100km (282.5mpg imperial) – that started with the lozenge-shaped, tandem-seat 2003 1L and the later L1 of 2009. The XL1 actually beats that by sipping just 0.9 liters with CO2 emissions of 21g/km.

Porsche 918 Spyder races toward production

OK, let's put the usual arguments to rest first: The Porsche 918 Spyder is going to be even faster than the Carrera GT in a straight line. That's based on Porsche's own computer simulations in anticipation of the production version of the gasoline-electric-powered 918 Spyder, which is due to roll off a dedicated line within a decommissioned paint shop at Porsche's Zuffenhausen, Germany, headquarters next year. The claimed 0-to-62-mph time is 2.8 seconds; 0-to-124 mph is 8.9 seconds, and top speed should be about 202 mph, thanks in part to series of active aerodynamic functions, including a multistage rear wing.
