Some cautionary reading for anyone who’s about to put a deposit on Toyota’s go-faster GT86 sports car – the TRD. We figured one yesterday, putting it through the same handling, braking and acceleration tests as we did the standard ’86 last year. Not for a full road test, mind; just to find out what it’d do.

At this point it seems only fair to point out that the Toyota Racing Developments version of the car isn’t an especially trick machine as tuned sports cars go. The departures from standard ’86 specification include larger alloy wheels, wider and stickier Yokohama Advan Sport tyres, a new exhaust, a revised rear diffuser panel and a sporty body kit.

Officially there’s no extra horsepower on offer here, no extra braking power and no stiffer suspension setup either. There’s an adjustable chassis, upgraded brakes and lighter forged alloys in the TRD catalogue, but they’re options: they’re not included for your £6.5k premium over a standard GT86.

Given all that, you wouldn’t expect the TRD to be any quicker accelerating than the standard car. In fact, it’s slower. On the same tarmac where we tested the GT86, the tuned car actually took a tenth of a second longer to hit 60mph from standing (7.4sec versus 7.5) proving more difficult to get off the line cleanly without bogging down with too few revs, or overheating the clutch with too many. Might have been the extra drag of the body, or tightness in the engine – but by 100mph the TRD was another six tenths slower than the standard car.
