The Mazda MX-5 Superlight version has been designed to add fun to the Frankfurt show and will not make production, the car maker has told Autocar.
"I've been looking to do something like this for ages," said Peter Birtwhistle, Mazda Europe's chief designer, "it's a bit of fun and it celebrates the 20th anniversary of the MX-5."
However he said it is unlikely the car will make production and is a design study for the direction of future MX-5s.
The Superlight weighs 995kg (down from 1080kg on the standard car), and features several racing touches: occupants sit on lightweight carbonfibre bucket seats and are held in place with four-point belts. Lightweight materials such as carbonfibre, fibreglass and aluminium also dominate the interior.
The car is powered by a 124bhp 1.8-litre four-pot with 123lb ft of torque. It remains in production-spec, but is linked to a Mazdaspeed cold air intake and exhaust system. It hits 62mph from a standstill in 8.9sec, averages 44.8mpg and emits 150g.km of Co2.
