Ep 4. Episode 4

The episode begins with presenters Paddy McGuinness, Freddie Flintoff, and Chris Harris heading to the Scottish Highlands to test three new hybrid hypercars - the Ferrari SF90, the McLaren Speedtail, and the Porsche 918 Spyder - on some of the most scenic driving roads in the world. As they push the limits of the vehicles on winding mountain passes and deserted highways, they also weigh in on the ethics and practicalities of owning one of these high-performance machines.

Later on, the trio heads to a test track to compare three cars from the 90s that each represented the pinnacle of automotive engineering in their own way - the Acura NSX, the Toyota Supra, and the Mazda RX-7. The presenters discuss the impact these cars had on the industry and put them through their paces to determine which is the ultimate 90s sports car.

As always, the episode also features a celebrity guest taking on the show's signature "Star in a Reasonably Priced Car" challenge. This week, comedian Romesh Ranganathan attempts to set a fast lap time in the show's specially modified Toyota GT86. Along the way, he shares some of his favorite cars and driving experiences and takes on a few surprises thrown in by the hosts.

Wrapping up the episode, the presenters take on a unique challenge inspired by the extreme temperatures experienced by cars in the deserts of the Middle East. They attempt to cook a full English breakfast using only the heat generated by the exhaust systems of three high-performance vehicles - the Audi RS6, the BMW M5, and the Mercedes-AMG E63S. As they grapple with the technical challenges of this unusual cooking method, they also explore the various features and quirks of these impressive cars.
