[Video] A wild ride over the bumps of Sebring
Back in 1973, a host of world class drivers were invited to compete in a new single-make race series, dreamt up by the legendary Roger Penske. Named the International Race of Champions, aka the IROC, the series would debut the following year, with the likes of Mark Donohue, George Follmer, A.J. Foyt, Richard Petty, and Bobby Unser taking to the wheels of identical Porsche 911 RSRs.
Based on the RS 3.0 road car, the 3.0-litre engine was tuned to develop 315bhp. With a wide body, fat tires and a large fiberglass whale-tail, only 15 were built, giving the 1974 IROC 911 something of a legendary status. As a result it's now considered one of the most prized, and valuable, classic 911s around. Back at the 2016 Amelia Island Auction, comedian Jerry Seinfeld sold his bright yellow model for $2.31 million (£1.86 million). But, that doesn’t make them museum pieces, as Leh Keen proves in this awesome video from the Classic 12 Hours of Sebring Pistons and Props…
If you're unfamiliar with Leh Keen he's something of a Porsche maestro, having raced Porsches for his whole career. It's that familiarity with 911s that makes him the perfect man to take us for a wild ride around the 3.74-mile Sebring circuit, paying little heed to the infamous bumps, which try to throw him off course.
Video aside, we could listen to this flat-six soundtrack all day long…
