Toyota is adding something to the Supra range that's guaranteed tomake collectors' toes curl. It's the same inline-6, but with special numbers inside

The GR Supra Jarama Racetrack Edition will be produced in extremely limited numbers;the exact global production not expected to be more than 90 units. It is going to be very rare – and, therefore, potentially valuable, as a future classic.

Mechanically the car is unchanged from any other Supra, but there are some styling upgrades. The only paint finish is Horizon Blue, and it rolls on 19-inch matte black alloy wheels. All GR Supra Jarama Racetrack Edition cars will have red brake callipers.

Inside there is the regulation carbon-fibre plaque, on the step-sill, which will include the car’s unique production and the outline of Jarama circuit. The Spanish race track, located close to Madrid, is where Toyota completed final validation testing of the current Supra.

Other cabin detail updates with this GR Supra Jarama Racetrack Edition include blue stitching on the Alcantara trim. This limited edition Supra is also equipped with the comprehensive Safety+ package.

Why is Toyota bothering to make only 90 of these GR Supra Jarama Racetrack Edition cars? It is all a play on numerology, and related to the ‘A90’ model code, which is what the current Supra is known as to Toyota insiders.
