It's one of the toughest engine assignments Cosworth has ever been given. For example, the T.50's 654-horsepower, 3.9-liter, naturally aspirated V12 has to rev from idle to its record-breaking 12,100 rpm redline in just three tenths of a second.

Maserati has stepped into a phone booth, and in September it'll debut its first proper, red-blooded supercar, as well as its first in-house engine, in decades. The MC20 and its 620-horsepower, twin-turbo V6 signal the Tridente's return to racing.

In partnership with the famed turbo snail-smiths at Garrett, Mercedes-Benz has announced it's developing electrically-assisted, 170,000 rpm turbochargers to eliminate turbo lag and boost the efficiency of its combustion engines.

A South Australian company is ready to go into full production with an innovative aftermarket kit that impressively cuts fuel consumption, particulates and carbon monoxide emissions from big diesel engines, asking only for a little water in return.

Camcon's Intelligent Valve Technology (IVT) replaces the camshaft with electric actuators for precise digital control over the air charge of any engine. Now, the company's focus is shifting from cars to heavy diesels and artificial intelligence.

It's only been a week, but we've already had to update our list of the world's most powerful cars, after Hennessey Performance surprised itself with an extreme dyno reading.

The gasoline age is giving way to electric, but there's still plenty of room for last-gasp improvements to the combustion engine.

Set to debut in a new 1.6-liter 4-cylinder Smartstream turbo engine, Hyundai's new valve tech is able to continuously change the duration of valve openings to suit driving conditions, which results in a 4 percent performance boost, 5 percent better fuel economy and 12 percent lower emissions.

British company Camcon Automotive has built a fully digital engine valve system, uncoupled from the crank, that offers unprecedented control over the combustion cycle. It enables some weird and wonderful ideas we've never seen before, such as giving 4-stroke engines brief 2-stroke power boosts​.

​Lock up your flywheels, folks, an American inventor is coming after them. RK Transportation is working on an idea that replaces an engine's flywheel with a lightweight rotor with embedded magnets, to apply pulses of electric torque just when they're needed in search of easier acceleration.

Forget variable length intakes and variable valve timing, Infiniti is going all the way and introducing variable cylinder compression ratios. The new VC-T turbo engine automatically adjusts between a high-powered 8:1 and a hugely efficient 14:1 ratio as you drive.

Earlier this year we saw the first example of a 3D-printed jet engine, now GE has announced the first 3D-printed part certified by the US Federal Aviation Administration (FAA) for a commercial jet engine. and will be retrofitted to over 400 GE90-94B jet engines on Boeing 777 aircraft.
