The new Toyota Supra has been spied again, this time at the Nurburgring in Germany.

This latest prototype has been fitted with what look to be production-ready tail lights. The new units use LEDs to create a unique signature, as is becoming increasingly common.

Elsewhere, this latest prototype doesn't look overly different to the car spied back in August. There's still a large collection false body panels underneath the camouflage, serving to further obscure the final design.

According to a report in AutoExpress, the new Supra could forego Toyota badging in favour of the company's Gazoo Racing sub-brand.

With roadsters and sports cars not enjoying the same sales success as in years gone by, Toyota and BMW have teamed up to develop a pair of two-door vehicles based on a front-engine, rear-wheel drive platform.

BMW's take on the platform, previewed with a concept car at Pebble Beach, will be a convertible successor to the Z4.

It's understood the Toyota version will be sold solely as a coupe. Externally, at least, the two cars have completely unique designs, although the Supra prototypes have used BMW wing mirrors.

For its next generation, the Z4 will ditch its current folding hardtop setup for a more traditional soft-top.

Drivetrains for both vehicles are yet to be confirmed, but a production sheet spied in May showed the Z4 will be available with a 145kW/320Nm 2.0-litre turbocharged four-cylinder engine, six-speed manual, and rear-wheel drive.

The rumour mill has indicated the new Z4 will be also be available with a six-cylinder option, while the Supra may come with a hybrid drivetrain. BMW told CarAdvice it plans to give the car a character of its own, so don't expect too much cross-over between the two cars.

A report in August suggested the Supra could be offered with a manual transmission, and a turbocharged six-cylinder engine developing over 400hp (298kW).
