The Koenigsegg Agera R is hand built by craftsmen in Sweden. Every example appears to be a work of art, and reviews tend to say that too. But one former owner says it's the opposite. In fact, he says the Agera R he was buying was "a hunk of shit." Koenigsegg doesn't see it that way.

The all-carbon wheels on the Koenigsegg Agera R are so light, you can toss them into the air and catch them.

Just what is the fastest car in the world? Over the last few days, no one seems especially sure anymore. The Bugatti Veyron Super Sport had held that record since 2010, but it was revoked over the weekend. Now the official title has reverted to the SSC Ultimate Aero — and SSC says their forthcoming Tuatra will be even …

With all of the talk this week about Koenigsegg exploring the concept of camless engines, I thought it might be fun to revisit one of their oldies-but-goodies: the CCR.

We met Christian von Koenigsegg, the father of Sweden's hypercars, while he was hanging out at Spyker's stand at the Geneva Motor Show. He told us something quite juicy there — that in about 10 years or so, automobile engines won't have camshafts anymore. He's been working on his camless engines for a while.

You thought you had a hard time when you lock your keys in your car. This guy had to pull them out of his $600,000 (£407,000 new) Koenigsegg CCR.

Having used the Ford Modular V8 as a launch pad, Koenigsegg reengineered this berserker mill for the Agera R hypercar from the ground up at its headquarters in Ängelholm, Sweden. Its goal? Specifically to get as many horses galloping as possible.

The opening and closing movements of the valves in an internal combustion engine have been controlled by camshaft rotation for around 150 years. The cam itself was invented by Al-Jazari in the year 1206 as part of a proto-drum machine. But now, in Koenigsegg's shop as it is in many other labs around the world, the cam …

Meet Robert Serwanski. He has the best job in the world. He's the chief test driver for Koenigsegg. That means he drives Agera Rs at the limit like you and I check our e-mail.

What's the difference between an Earl Scheib-esque econo paint job and that of a seven-figure, carbon-fiber hypercar? That "orange peel" look, for one, and also the thickness of the clearcoat. That, and around 200 hours of polishing.
