Cutaway shots of the Volkswagen Golf GTI Design Vision GTI concept have revealed that it appears to use a new VR6 engine, as opposed to the previously rumoured V6.
Volkswagen has not confirmed whether the engine is indeed a VR6 but, judging by the configuration of the intake and exhaust systems, it seems likely to be the case.
The new six-cylinder engine, which has a single cylinder head and a claimed 15-degree angle between its rows of cylinders, is said to displace 3.0 litres. Thanks to direct fuel injection and twin turbochargers, its output is stated to be a substantial 496bhp and 413lb ft.
It's reputedly set to see service in future models, which may include high-performance versions of the Volkswagen CC and the recently unveiled CrossBlue coupé — although the engine will most likely be detuned for economy, emissions and drivability reasons.
It's not yet known whether the new unit is a development of an existing VR6 or an all-new engine, or if it will be available in UK models, but it is thought that its smaller capacity - compared to recent VR6 units - is a result of a Chinese-market specific tax break.
The new Golf Design Vision concept, which is equipped with a transversely mounted 496bhp version of the new VR6, is capable of accelerating from 0-62mph in a supercar-rivalling 3.9sec. Its top speed is 190mph.
