Race Car Of The Day: Highcroft Racing Nissan DeltaWing

Could this be the  future of the racing car? It’s called the Nissan DeltaWing and it’s part road racer, part futuristic IndyCar, part salt-flat runner, and looks like a modern interpretation of the Keaton-era Batmobile. Not only is it lighter and more aerodynamic than the rest of the endurance racing field, it uses half the fuel, which not only makes it more economical, but more competitive. And against all odds, it’s coming to the 24 Hours of LeMans this year

The DeltaWing was a joint project between former Lola design chief Ben Bowlby and Chip Ganassi Racing, and pitched as the future of IndyCar. IndyCar passed on the design, calling the DeltaWing too radical, and instead falling back on the latest interpretation of the Dallara chassis the series has been using for years.
Bowlby and crew, along with American racing legend Dan Gurney and forward-thinker Don Panoz, shrugged off the rejection and teamed with Duncan Dayton's Highcroft Racing operation, based in Danbury, Connecticut. Then Michelin joined as tyre supplier; a crucial element, as it lets the team set the suspension up perfectly to match the tyres. Now Nissan has joined the team, appending its name to the project and  - more importantly  - supplying the engine.

If you’ve ever seen Nissan’s Juke crossover, you’re already vaguely familiar with what’s powering the DeltaWing. The range-topping Juke DIG-T (Direct Injection Gasoline – Turbocharged) in Japan comes packing a turbo’d 1.6-litre four cylinder engine putting out a little over 180 bhp, but in racetrim knocks out 300 hp.
To reduce drag and optimize weight bias, the engine is mid-mounted with power is sent to the rear wheels. More intriguingly, with both the engine and driver mounted far back in the carbonfibre chassis, the ultra-thin front tyres don’t have to move much to elicit a change in direction. If you’re thinking those miserly front wheels can’t be stable at speed, check the video below of the DeltaWing testing at Buttonwillow Raceway in Southern California.

Compared to the LeMans leaders in the LMP1 class, including the recently revealed 510 bhp Audi R18 Ultra, the DeltaWing is down on both power and traction, but that’s not the name of the game when it comes to endurance racing. The DeltaWing weighs in at a svelte 1,300 lbs with a full tank of fuel and driver on board – about half what a comparable LMP1 car weighs. Couple that low tonnage with its slippery shape, good for a claimed 50% reduction in aerodynamic drag, and suddenly the DeltaWing is competitive.
Just as important as its aero advantage and reduced weight is the boost in fuel economy, which Nissan estimates will be about double that of an LMP1 car. Over the course of a 24 hour race, that means fewer pit stops to refuel and – with its lightened load – a reduced need for tyre changes and brake swaps. That equates to more laps over less time, and that’s what wins LeMans.
Except, it can’t win.

Note All American Racing and Panoz Decals - theres a lot of experience behind this car:

The DeltaWing is running in a class of one, taking the 'Garage 56' spot at LeMans and wearing a '0'″ on its sides, both of which indicate that it’s a noncompetitive, exhibition racer; a rolling proof of concept that gets to play with the big boys and put on a show for the ACO, the organizing body of the race. But that doesn’t mean the DeltaWing’s participation isn’t relevant.
“As motor racing rulebooks have become tighter over time, racing cars look more and more similar and the technology used has had less and less relevance to road car development,” says Executive VP at Nissan Andy Palmer. “Nissan DeltaWing aims to change that.” And change that they will, beginning with its first public exhibition at Sebring International Raceway this Thursday and followed by taking the exclusive 56th slot at the 24 Hours of LeMans this June.
