SPORTS CARS: N/A Porsche 718 Cayman GTS vs Turbo Audi TT RS | Stig's Garage ft. Becky Evans

Naturally aspirated or turbocharged is a question that often divides the motoring world, so in this instalment of Stig’s Garage, we have two German sports cars that both make 395bhp to battle it out on the Top Gear test track. The 718 Cayman GTS has a naturally aspirated 4.0-litre flat-six and a 6-speed manual gearbox. Its contender, the TT RS, has a 2.5-litre turbocharged five-cylinder under the bonnet. Becky reckons the Cayman is more of a driver's car but also knows the Audi has all the mechanical grip and power to take on the Porsche. Time for Becky Evans to make her predictions and let the Stig do what the Stig does best. What's your money on?
