How Jaguar Pulled Off The E-Pace Barrel Roll

Seeing a Guinness World Record being broken is always entertaining, but some may not put too much thought into the sheer amount preparation needed to pull off something like the E-Pace barrel roll.

The final product usually looks perfectly orchestrated, but it took Jaguar 33 test jumps before making that all important world-record-breaking barrel roll. Not all of those test landings went according to plan either. The lightly-modified E-Pace landed on its roof, sides and rear-end multiple time before the Jaguar team managed to find the perfect approach speeds and angles.

Not only did the calculations have to be on point, so did stunt driver Terry Grant. During the jump that lasted just over 1.5 seconds, Terry was subjected to forces of 5.5G whilst controlling a flying vehicle and trying to stick the landing with just a 10 mm (0.4 in) margin for error. All these calculations were made after running through a staggering 756 hours of engineering simulation time.

Of course no stunt test is without a few scratches and the E-Pace suffered plenty of cosmetic damage with a corner of the bumper looking to be held together by duct tape. But structurally, the integrity of the car was exactly the same as when they started, meaning those production vehicles rolling off showroom floors and into garages can definitely take a beating.

I'd like to rocket a car onto what is essentially a bouncy house for adults. A few of those rolls look damaging and the test mule managed to tear through the bouncy house at least one from what I can see, amazed all it needed was some duct tape and nothing else was damaged.

Duct tape fixes everything. But we don't know the extent of damages that it sustained, we only see captures of how they put it all back together with duct tape being exposed. That huge "bouncy house" does look like fun though but I can imagine the tumbling still takes a toll on the body for sure.

A few of those tests were done by a computer so nobody was in there, but I'm sure the driver went through plenty of them as well. He'll be fine, stunt drivers know how to brace themselves properly in those kind of rollovers. But completing the roll with a 10 mm (0.4 in) margin for error is just amazing to me.

Apparently the roll took 6 months of planning and testing before they nailed it, meaning the E-Pace was pretty much completed 6 months ago.

Most likely the basics like engine tuning, steering, functions needed to make the roll were completed 6 months ago and since then Jaguar has been ironing out any electronic bugs while preparing for the record breaking roll.
