Koenigsegg

Koenigsegg's latest breakthrough comes in the form of a compact, power/torque-dense electric motor. The new Quark motor will help the boundary-smashing Gemera four-seater achieve sprint times formerly reserved for the quickest electric coupes.

Man stands next to car and talks about it: it's a video format you've seen a thousand times. But this guy's name is on the back of the car, and the car is the extraordinary Koenigsegg Jesko. Join the man as he presents, then flogs, his latest beast.

Koenigsegg debuts the Gemera, the "world's first mega-GT." This all-out performance machine seats four and packs some of Koenigsegg's most impressive tech, including a gearbox-free KDD powertrain with a small camless Freevalve twin-turbo.

Koenigsegg doesn't have to call the new Jesko Absolut the world's fastest car, because referring to it as the fastest Koenigsegg amounts to the same thing. Packing 1,600 hp and fins like a fighter jet, the Absolut is an all-out speed machine.

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.
