This Old Mercedes Sounds Like A V12 F1 Car!

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 fifth episode of our series, our tame racing driver welcomes the Mercedes S600 limo… Wait, what?! Fear not, because while the W140-era Merc S-class is famously quiet (it even had double-glazed windows, so you could hear a pin drop in the cabin) it also had the same V12 that powered the original Pagani Zonda. And thanks to a trick exhaust, this one sounds like an old Formula One car. Join The Stig, and host Becky Evans, to hear just what an oh-so-special exhaust can do to an old Merc limo… Top Gear Tunnel Run is sponsored by the Las Vegas Convention and Visitors Authority Car: Mercedes S600 Engine: n/a V12 Power: 439bhp Price: £60,000 Top speed: 155mph Noise: Subscribe to Top Gear for more videos: WATCH MORE TOP GEAR: First Looks: https://bit.
