Koenigsegg details the madness of his Light Speed Tourbillon Transmission

We always tune in when Christian von Koenigsegg steps in front of the camera for another tour of his car company's new technology and facilities. He's obviously enthusiastic about what's being designed and built in Angelholm, Sweden, but not overly so (not in his videos, at least), he's talks about technology in simple terms, and, best of all, the stuff coming out of those factory machines is not only innovative, it's beautiful. The fearless leader checks all the boxes again with this quick look at the new transmission and twin-turbo 5.0-liter V8 block going in the two-seater Jesko and available for the four-seater Gemera.

A quick refresher on the LSTT, or Light Speed Tourbillon Transmission. During Gemera development, engineers wondered if the Gemera could fit the TTV8 and Light Speed Transmission (LST) from the Jesko into an engine bay designed for the Tiny Friendly Giant (TFG) three-cylinder engine and Direct Drive transmission from the Koenigsegg Regera. The engineers answered that question in the affirmative with what's now called the LSTT, the addition of "tourbillon" referring to a mechanical feature that makes a wristwatch more accurate. On top of giving the Gemera a huge boost in available output, reworking the LST for its new employment made it smaller, lighter, and better. It's super compact form fits nine gears and weighs just 198 pounds including the attached starter motor; the eight-speed dual-clutch Tremec TR-9090 for the Chevrolet Corvette weighs 307 pounds empty in its lightest configuration.

A tour of the 5.0-liter V8's rotating assembly shows Koenigsegg doesn't skimp on artwork. The ceramic coating on the top surfaces of the forged pistons is etched with the Koenigsegg logo, the connecting rods are etched with the Koenigsegg name, as are the anodized timing chain guides. Christian says the entire engine is "under 200 kilos," or 441 pounds. That's not far off the 445-pound weight of Ford's Gen 3 5.0-liter V8, but the Koenigsegg carries two turbos and their ancillaries. He also shows off bits like the 3D-printed thermostat, intake plenum, and Inconel exhaust manifold, all of it art.

After that, a trip to the dyno to see what the motor can do on E85 and on our own 91 octane. If you like mechanical bits and what they can do when cost is no object, you should have a watch.
