Cold start of a Bugatti Chiron and revving a Koenigsegg Jesko

The Bugatti Chiron Super Sport 300+ is a rare and great car that was first introduced in 2019 and is one of the few cars to exceed 300 mph (482 km / h).

In fact, it was the first with a prototype without a speed limiter.

Used this prototype a modified 8.0 liter W16 engine, 1177 kW output without changes to the gearbox or all-wheel drive, as well as numerous measures to save weight. Bugatti took over the engine in limited production, which included a new exhaust.

It turns out that an exhaust tuned to produce as much power as possible with little consideration for emissions sounds darn good.

A video from October 2020 shows a Chiron Super Sport 300+ taking off at a rainy Bonhams event (past the flags around the car) and it sounds like an old warplane from WWII. Or in short: absolutely brilliant.

Anyone who wants to drive straight ahead very quickly and has an eight-digit bank account (no overdraft) is hard to beat with the Chiron Super Sport.

Anyone who wants to drive straight ahead very quickly and has an eight-digit bank account (no overdraft) is hard to beat with the Chiron Super Sport.

It’s a different kind of awe than Koenigsegg’s recent engine video, which shows the 5.1-liter, twin-turbocharged V8 going from idle to the 7500 rpm limit in less than a second.

That’s not far from how fast a superbike engine can spin that is about a fifth the size with much smaller and lighter internals.

Koenigsegg says his new V8 crankshaft weighs just 12.5 pounds, while the pistons themselves weigh just 290 grams each.

The connecting rods are made from “Premium Swedish Steel” and weigh 540 g each, including screws, which is apparently as light as the titanium units of previous generations but is stronger. How this is possible is a mystery to me.

More interestingly, the design of the motor includes a long stroke which is usually not well suited for fast, high revving applications.
