Although production of the Ford GT ended last year, it’s still attracting the interests of elite tuners. Branded the Avro 720 Mirage, this is the latest example to roll out of Roush’s tuning centre, successor to the not-exactly-slow Roush 600 RE. The name refers to Avro Motor Cars, a supercar specialist that helped develop the spec and will be the only stockist.Power comes from an uprated supercharger attached to the GT’s 5.4-litre mid-mounted V8, delivering 720bhp at 6950rpm and 627lb ft of torque at 4800rpm. Running gear has been tweaked to cope with the extra urge – ride height is 25mm lower, the rear track has been increased and suspension is fully adjustable.Official performance figures have yet to be released – we’ll do everything to bring them to you as soon as we can – but Roush reckons the car will be capable of achieving a 220mph top speed. Prices have yet to be confirmed, but only ten cars will be built. The previous Roush 600 RE cost £141,000 and it’s anticipated the Avro 720 will probably command a sizeable premium.
