The Koenigsegg Jesko Has The World's Fastest Revving Production Engine

Engine / Comments

These figures are simply unheard of.

When the Lexus LFA finally arrived with its spectacular V10 engine, one tidbit of information stood out for car nerds. It could gain and lose revs so fast that a traditional analog tachometer simply couldn't keep up, hence the digital unit. This Yamaha-tuned engine was so quick that it could get from idle to 9,000 rpm in just 0.6 seconds. More recently, the GMA T.50's Cosworth-developed V12 was revealed with the ability to get from idle to 12,100 rpm in just 0.3 seconds, which translates to 28,400 rpm per second. Both of these spectacular engines are free-breathing, but a twin-turbo V8 has just taken a dump all over their accomplishments, as the Koenigsegg Jesko's engine has been revealed to be MUCH faster than either of these in a new video presented by Christian von Koenigsegg himself.

Von Koenigsegg explains that the Jesko's V8 - a 5.0-liter twin-turbo motor generating over 1,600 horsepower - is continually undergoing refinement and development to meet ever-tightening emissions regulations, as well as the company's own standards for performance. Among those standards are the goals of making the engine even lighter and more responsive than ever. There's no point in having a sequential gearbox so quick that you call it Light Speed if you're losing some of that speed to inertia in the engine, so both the engine and the transmission were developed alongside each other. As a result, the engine has incredibly low inertia, giving you astonishing throttle response throughout the rev range. So just how fast is this engine? Very, is the short answer.

Remember how the GMA T.50 that we mentioned at the outset was capable of up to 28,400 rpm/s? Well, the Jesko Attack's engine (and, by extension, that of the Jesko Absolut) can rev from idle to 7,800 rpm (its neutral redline; while in gear, the redline is 8,500 rpm) in just 213 milliseconds. That's just over a third of the time it takes the LFA to reach redline and translates to an astonishing average of 31,700 rpm/s. What's even more astonishing is that, under load, the engine can rev even quicker, with engineers having recorded peaks of up to 46,000 rpm/s. If you ever thought that turbocharging automatically meant lag and poor throttle response, think again. Koenigsegg is once again rewriting the rule books.
