Toyota’s keenly anticipated fifth-gen Supra will be revealed on January 14 at the Detroit motor show, but the Japanese car-making giant’s thunder has been stolen by these leaked images of the new coupe.

The pics first aired on fan site SupraMkV.com but have since gone viral. Although grainy, the images show the car undisguised for the first time, and the end result is easy on the eye. It retains most of the styling cues of the striking FT-1 concept, although the front bumper and air intakes have been completely redesigned.

As evident from the pics, the three main air intakes are flanked by what appear to be brake cooling ducts just ahead of the front wheelarches. The clamshell bonnet doesn’t feature the central black power bulge worn by the show car, but the double-bubble roof carries over.

Bulging haunches give the Supra a menacing stance, while the prominent ducktail rear spoiler and aggressively sculpted taillights ensure it won’t be mistaken for anything else – especially not the new BMW Z4, with which it shares its platform and drivetrain.

Other visual niceties include a massive rear diffuser, through which protrude a pair of round tailpipes. The classic Supra logo is also back, along with the letters ‘GR’ for Gazoo Racing (Toyota’s in-house motorsport arm).

Under the bonnet sits the same 3.0-litre inline turbo six-pot as the latest BeeEm Z4, and outputs of around 380bhp and 500Nm should propel the circa-1500kg coupe from standstill to 100kph in under 5sec and on to a top speed of 260kph-plus.

An eight-speed auto will be the sole transmission offered initially, but a manual may join the range later. The Supra line-up will also be supplemented by an entry-level four-cylinder turbo variant in due course.

We’ve already driven BMW’s latest Z4 and can confirm it’s an entertaining driver’s car, so what remains to be seen is how well Toyota’s boffins have been able to interpret the recipe.

The early signs are positive, as the Supra features 50:50 weight distribution over front and rear axles, and prototypes have been seen pounding around the Nurburgring, with the BMW M4 and Porsche 911 used as dynamic benchmarks.
