Koenigsegg

With its 1,500-horsepower, single-speed direct drive hybrid powertrain, the Regera was built to destroy the 0-400-0 test. And destroy it it did.

​Porsche’s circular 12.6 km (7.8 mile) test track at Nardò in Italy has been renovated and is again open for business. More than just the banked high speed test track, the Nardò Technical Center contains 20 test tracks on over 700 hectares, and has been used by 90 automotive companies in the past.

Beating some 1,600 horsepower out of a 5-liter twin-turbo V8 is no small achievement. Creating a new multi-clutch transmission that can skip instantly from any gear to any other is amazing. But the new King Koenigsegg also has its sights set on becoming the world's first 300mph production car.

​Hypercar buyers love carbon fiber, and Koenigsegg has just released the carbon-iest hypercar ever with this "naked carbon'" KNC Regera, which strips away any lacquer, varnish and even the thin layer of epoxy, to present a car finished in nothing but bare carbon fiber.

​With the likes of Bugatti and Hennessey jostling for pole position, there is plenty happening at the high-end of the hypercar game. But it looks like there is a new top dog in town, at least in terms of two-way land speed records.

Just weeks after Bugatti set a new 0-400-0 km/h world record in the Chiron, Koenigsegg has smashed it with the Agera RS. The plucky (or mad) Swedes shaved almost five seconds from the record, and did it without the considerable might of the VW Group for backing.

Our Monterey Car Week report covers the 113 cars with estimates over US$1 million and what happened to them.

Car makers haven't given up on internal combustion yet. Along with a push towards downsized turbo power, some of the smartest engineers in the world are using new techniques to make their engines more efficient. Here are a few of the most interesting modern takes on the internal combustion engine.

Our regular Monterey Car Week auction preview lists no less than 113 cars with estimates exceeding US$1 million. Read on for pictures, links to auction descriptions and all the key info.

The rash of supercars we have seen since the new millennium began are already beginning to ripen at auction, and no less than 17 modern supercars are expected to sell for more than a million dollars at Monterey Car Week this year.

At the New York Auto Show, Koenigsegg has revealed the latest US customer-spec Agera RS, an icy megacar dubbed the Agera RS1. US roadways will get a little colder and a lot faster - and no amount of tire-smoking acceleration will melt this 1,360-hp rolling iceberg.

Spyker unveiled the topless version of its supercar, the C8 Preliator, at the Geneva Motor Show with a surprise announcement. The small-volume carmaker is dropping the Audi powertrain originally planned for the Preliator in favor of an engine from fellow supercar maker Koenigsegg.
