'Colossal idiot' Hammond apologies to family

Richard Hammond apologised to his wife and children on Sunday after a crash in a £2 million (R32m) electric supercar left him seconds away from being ‘incinerated’.

The accident-prone TV presenter, who was airlifted to hospital in Switzerland after the fireball crash in the electric-powered Rimac Concept One, said he had "binned it again" and felt like a "colossal idiot".

In a video message entitled I’m Not Dead, posted on the Drive Tribe blog from his hospital bed, the 47-year-old said he was sorry for putting his family through the mill again 11 years after a crash on Top Gear put him in a coma.

Earlier this year he was left unconscious after falling from a motorbike in Africa, and last month he vowed not to do any more dangerous stunts for the sake of his "beautiful" family. Hammond, who fractured his knee, thanked medical staff after his latest brush with death which happened when he careered off a hillside while filming for Amazon’s The Grand Tour on Saturday. He joked that doctors would be giving him a ‘Swiss army knee’ and that co-presenter James May had smuggled gin into the hospital.

However, he said the "most important" thing was to issue a heartfelt apology to his wife Amanda and daughters, Izzy, 16, and Willow, 13.

Revealing how lucky Hammond had been to escape alive from the burning Rimac Concept One car, The Grand Tour’s executive producer Andy Wilman said: "Jeremy [Clarkson] and James both raced down to the scene of the crash as soon as it happened. "When they saw the wreckage on fire they thought Richard was dead. They were staggered he had got out alive because there was just nothing left."

He told the Sunday Mirror: "If Richard had been a few seconds slower getting out he would have been incinerated." A witness who filmed the moment Hammond crashed said: "He crashed into the speed limit sign and off the road into the field below. He went down the hill about five or six metres.

"I would have been there about 20 seconds after the crash. The car was already burning. I saw fire. It was at the front. The car had done a 180-degree turn."

Apprentice engineer David, who did not wish to give his surname, added: "I saw the driver getting out of the car, the door was open. In fact, I don’t think the door was even there. That’s the reason he could get out so fast. There was a spectator who helped him get away from the car.

"Ten seconds later and a fireman was already running down to the burning car. There were explosions, bangs – like fireworks. And dark smoke. Poisonous fumes from the burning plastics."

It is still unknown what caused the crash during a practice run for the Hemberg Hill Climb. There is also an investigation underway into what made the Rimac Concept One burst into flames as it carries no fuel.

354km/h electric marvel

The Rimac Concept One has a price tag of £2 million (R32m) and only eight are thought to have been made.

It has a top speed of 354km/h and can accelerate from 0-60mph (96km/h) in 2.4 seconds.

Croatian manufacturer Rimac Automobili calls it the first all-electric hypercar.

Lithium nickel manganese cobalt oxide batteries power four electric motors, one driving each wheel.

It has a range of around 350km on one charge.

The body is carbon fibre and safety features include traction control and ‘safety disconnect systems’ in case of a crash.

Richard Hammond’s crash: Why did his EV catch fire?

There are few people outside of professional racing and stunt driving who have dared and survived the crashes Richard Hammond has.

In 2006, whilst piloting a Vampire jet-powered dragster, Hammond survived a crash at 463km/h – caused by tyre failure. Little more than a decade later, the affectionately nicknamed ‘Hamster’ has survived yet another extraordinary brush with that ‘void’ which should never be tested, beyond the fold of supercar adhesion limits.

By now we’ve all seen the video, those corresponding images and know what happened in Switzerland, at the Hemberg hill climb circuit. Hammond misjudged his entry speed into a sharp corner at the end of a segment being filmed for the forthcoming Grand Tour season, and the Rimac supercar he was piloting, ended up rolling down one of those characteristically peaceful Swiss embankments, onto a perfectly kept meadow.

What happened when the momentum of Hammond’s crash came to an end, and he had the opportunity to scramble away from the Rimac he was driving, to safety, is the true issue. The car started to burn.

Supercars burn. This one shouldn’t

Supercars burning, especially after they’ve crashed and fuel encounters scalding exhausts or engine component surfaces, is nothing new. But the Rimac Concept One Hammond was driving, is no ordinary supercar. Its output and performance numbers are extraordinary: 1000kW and 0-100km/h in 2.5 seconds.

But what is most notable about the Rimac Concept One, is that it carries no fuel. This incredibly fast car is battery powered and therefore Hammond’s crash begs the rather troubling question, if the Rimac had no 95 octane onboard, why did it catch fire?

The preliminary answer appears to be heat. And oil. If you’ve ever experience the heat surge from your laptop or device, uncomfortably warming either your thighs or palm, you’ll know that modern lithium-ion batteries can generate tremendous heat surges in operation. In the Rimac Concept One, you are multiplying that issue exponentially.

Electric cars generate a lot of heat as their batteries discharge at a high rate, to provide the required performance. Hammond’s hill climb run would have taxed the Concept One’s batteries and electric motors to their utmost, draining those batteries of energy and testing the electric motors, which are burdened with converting all that stowed energy to 1000kW.

Allowing the entire system to cope with its heat generation are oil-coolers, which manage any thermal issues around the permanent magnet motors, of which the Rimac has four. Those motors also happen to be located in each wheel, which mean if you manage to kerb a Rimac Concept One hard enough, or flip it and the wheels break off, you have oil leaking onto a lot of very hot electric wiring. This, in all probability, is what ignited Hammond’s car after his crash.

Better packaging required

The wisdom to be gleaned? Electric car manufacturers need to consider just how much heat the battery packs and magnet motors used in their vehicles generate, and the risk of high voltage systems and wiring present throughout the structure.

If oil coolers are necessary, they should have reservoirs and plumbing which is puncture proof, and the issue is that electric vehicle design has placed a premium on the torque vectoring benefit of having motors in the wheels, which make any cooling system particularly vulnerable to shearing during a substantial impact.

Supercars always test the limits of engineering, refining concepts which work in theory. If electric cars are going to become mainstream, the technology they apply must work in the high-performance automotive realm too – not merely as urban runabouts.

Richard Hammond’s crash, and the curious detail of his ‘pure electric’ car catching fire in much the way an internal combustion car would be expected to, could be a greatly beneficial moment in the history of electric vehicle design.

The one where we all realised that batteries and electric motors run warm, and if oil is kept on-board to cool those electric motors, the risk of fire is a lot higher than any of us currently anticipate.

Watch: Richard Hammond speaks about crash

Last month Richard Hammond cheated death when he crashed an 800kW Ricac Concept One electric supercar during a hillclimb event in Switzerland.

The Top Gear and Grand Tour star managed to escape from the supercar just in the nick of time, before it burst into flames, and escaped with an injured knee that will see him hobbling around on crutches for the next few months.

But best you hear it all from the man himself. Hammond and his wife opened up about the ordeal during an interview with the UK’s ITV recently, accompanied by his wife Mindy, who got to explain her own toils, which involved looking after the injured ‘nine-year-old’ Richard after his operation.

And if you’ve ever wondered about the ‘science’ involved in driving off a hill, this video should prove rather insightful.
