The winner of Autocar's Innovation Award for 2024 is Catesby Tunnel, the 1.7-mile hole through the Northamptonshire countryside that once formed part of the Great Central Railway and has recently been repurposed as a globally unique aerodynamic testing facility.
"Fourteen years ago, I was thinking about how we test our designs," says Rob Lewis, the brilliant aerodynamicist once of BAR and Honda Formula 1 teams and now managing director of Totalsim, which specialises in computational fluid dynamics (CFD), explaining how today's facility came into being.
"We would optimise things in CFD, but in the UK our wind tunnel choices were MIRA or a scale tunnel, and we didn't have a fullscale moving-ground automotive tunnel. I was Googling and found Catesby Tunnel, just up the road from our office in Brackley, on the same train line. So I started kicking the idea around," he tells us.
Lewis had been working with Prodrive and discovered that some of its engineers had been testing race cars using a tunnel called Laurel Hill in the US, run by Chip Ganassi Racing.
"That proved it works," says Lewis. "But how could it not? You've got a controlled environment and a car moving along a body of air."

BEST DREAM CAR FORD MUSTANG
V 8-engined muscle cars are very thin on the ground in the UK, your only options being the Chevrolet Corvette (which is really more of a sports car anyway) and the new Ford Mustang - a 440bhp bruiser that you can now buy for a shade over £55,000, making it the cheapest V8 car of any kind on the market.
BEST LARGE CAR KIA EV9 - BEST SMALL CAR RENAULT CLIO
Us Europeans don't tend to think of Kia as a player in the large car market, which might be one of the reasons why the EV9 has made such a splash since its introduction to our shores at the beginning of this year.

BEST HYBRID BMW 5 SERIES - BEST SALOON VOLKSWAGEN ID 7
When BMW introduced a 545e version of the previous-generation 5 Series, it was a real 'have your cake, eat it and lose weight' kind of car: a plug-in hybrid that ticked all the sensible company car boxes while also a decent sports saloon with a wonderful straight-six engine.
