Toyota GR Supra v Porsche Cayman GTS v Lotus Emira: Endangered Sports Cars

These three sports cars have a lot in common - each has a six-cylinder engine, a manual gearbox, and won't be around for much longer. But rather than cry about it, we thought we'd take these 'endangered' sports cars to Bedford Autodrome for a series of challenges, to see which is best while celebrating the different ways they go about things - we have two mid engined cars and one front engined; a supercharged V6, a naturally-aspirated flat-six and a turbocharged straight-six. The question is, which one would you have?
