Porsche Taycan sets new Guinness World Record : fastest speed driven by a vehicle in an enclosed building.

Even when circumstances mean that being indoors is the safe and, at times, unexciting option, racer Leh Keen recently found a way to make being inside considerably less boring. Racing driver Leh Keen has accelerated the Porsche Taycan to 165.1 km/h inside an exhibition hall in New Orleans, Louisiana. In doing so, he set the world record for the fastest speed driven by a vehicle in an enclosed building.

Strictly enforced rules

Leh Keen - Guinness World Record - Porsche Taycan - fastest speed indoor building There’s a Guinness World Records title for the fastest speed by a vehicle indoors. Until recently, that top speed stood at  at 138.4 km/h. The rules – strictly enforced by Guinness World Records – are daunting. Keen had to start his record attempt and finish it at a standstill. All this must happen within the space of the building without a run up. With the absence of a safety net and open doors open, it means Keen had no escape route in case something went wrong For good reasons, therefore, the record has stood for  almost 8 years. The previous record was set February 23 2013 by Mikko Hirvonen (Finland) driving a Speed Car XTRM Crosskart (Spain) at the Helsinki Expo Centre, Helsinki, Finland.

Nevertheless, Keen proceeded enthusiastically with his planning. He required a car that was surefooted in challenging conditions, a vehicle that’s among the hardest accelerating and, crucially, hardest decelerating cars on sale today and that he would trust his life with in order to break the record safely. The car that met this criteria was the all-electric Taycan Turbo S (Taycan Turbo S: CO2 emissions combined 0 g/km, Electricity consumption combined 28.5 kwh/100 km), with all-wheel drive to maximise grip, powerful carbon ceramic brakes and the ability to accelerate to 100 km/h from a standstill in just 2.8 seconds.

Selecting the right building was just as challenging. Enter the Ernest N. Morial Convention Centre in New Orleans, Louisiana. At just over one million square feet, the convention centre boasts the largest contiguous exhibit hall in the United States, ideal for the distance it provided. However, like many other indoor facilities, the polished concrete surface replicated ice when being driven over at speed.

“I didn’t really appreciate the scale of the record attempt until my first exploratory run. The surface is so unpredictable, so slick, that you have to have complete trust in your car. It truly was like ice – and you’re accelerating flat out, facing a really hard wall at the end. Suddenly, even in a massive space like the one we had, it seems very small,” said Keen after his record attempt. “I could feel the Taycan’s systems figuring it out, working so hard to keep me heading straight – it was such an impressive feat. To accelerate so hard on such an erratic surface was incredible. Not for a moment did a doubt I could do it.”

The strategy

Leh’s strategy was to build up slowly, with low speed exploratory runs. The stock road tyres were preheated as a precaution. When it came to the record attempt, one run was all it took. “I did take a moment on the starting line – knowing I was going to have to go as fast as I could, and stop again, all before reaching the wall I was facing. It got my attention. I used the car’s launch control and the Porsche Taycan just hooked up – the sensation of speed indoors, even in such a big space, is enormous – that wall rushed up fast. I was gentle on the brakes in the end – the Taycan’s brakes were more than up to the job. Of course, I didn’t look down at my speed so it came as a surprise and a relief that I’d beaten the record, and by such a margin. It was a rush! I’m thankful to Porsche for trusting my abilities and for their preparations and encouragement – 165,1 km/h inside a building. What was I thinking?”
