From its HSV lookalike snout to its billet-propped bootlid wing, this car makes even the already-tough M6 look tame.
With 406kW on tap – versus the stock M6's 373kW – it's got the muscles to match its looks, too.
It's called Tension, and its builder, German tuning company AC Schnitzer's quick to point out that it's a concept only.
Torque's also up on the standard M6's maximum output: 540Nm at 6200rpm vs 520Nm at 6100rpm.
Schnitzer says the extra grunt came from reworking the 5.0-litre V10's engine management system, and fitting a new exhaust manifold and sports rear muffler with tailpipe trims.
The standard M6's top speed is limited to 250km/h. Thanks to its Vmax delimiter, this car runs out of puff only when it hits 325km/h.
