Hyundai's amazing 200kW 2l four

It may be a boring Hyundai plastic engine cover. Underneath we’re talking S3 humbling power levels though…

Hyundai’s unveiled its latest direct-injection turbocharged engine at the New York motor show and the numbers are startling.

Ever since the Hyundai/Kia corporate family showed off its 213kW, direct-injection turbo engine in the Kia Koup concept two years ago engine technology acolytes have been watching developments with a keen sense of anticipation. Now, the wait is over…

Hyundai’s new Sonata range rolled onto the display stand at the New York auto show on Wednesday sporting a Theta II 2l turbo engine which should give European engine designers plenty to worry about.

New Sonata. Looks good. Don't try to drop one at the lights though...

Thought only BMW did twin-scroll?

The South Korean four-cylinder direct injection turbo employs twin-scroll turbocharging technology and runs a startlingly low 9.5:1 compression ratio.

Those familiar with twin-scroll forced induction will know its plumbing allows one to mount the turbo housing as an integral casting with the exhaust manifold, enabling the shortest (most efficient) possible flow path for gas exchange.

With the Theta II engine boosting at 1.2bar it produces 200kW and peak rotational force of 365Nm across a rather generous engine speed range of 1 800-4 500r/min. Hyundai says with its new six-speed automatic transmission Sonata 2.0T should return 7l/100km.

Who says you can’t have your cake and eat it?
