The Stig’s secret subterranean lair is the perfect place to make a lot of noise with a lot of noisy cars. Welcome to Top Gear Tunnel Run.

In the forth episode of our series, our tame racing driver welcomes what is still the quickest Caterham you can buy, and the most powerful Caterham ever built.

It’s a Caterham Seven 620R, and although it was launched way back in 2013, it does 0–62 in just 2.7 seconds... in first gear. And the exhaust pokes out right under the driver, sounds like a supersonic hornet and sometimes it spits fire.

Join The Stig, and host Becky Evans, to hear this little firecracker in action…
