Update: Observers of the GTR-LM at NCM Motorsports Park in Kentucky have confirmed the sound of high-power electric vans at speed around the track — answering a fundamental question posed below.
Well, I’ll be damned!
The shocking design and tech solutions of the all-new Nissan LMP1 car continue to mystify in the runup to LeMans 2015. The tech specs are out and included here, along with a fascinating video revealing one of the GT-R LM NISMO’s big secret weapons: vacuum aero.
Nissan shows these full-length channels in the design in the below video, describing how the full-length piping helps suck the car into the track pavement. Combined with the massive nose planes and much-longer-than Audi hood, the LM NISMO is quite the intriguing new contender.
These aero ideas are an interesting application of Chaparral 2J racing tech in the 1960s, where ducted fans created an unbeatable racecar … until the tech was banned.
No word from Nissan on the presence of fans or forced airflow inside these vacuum tubes, or if this air is used for any engine or brake cooling. If we had to guess, we’d say all the above and more is happening inside these magic pipes.
The LM NISMO is actually quite beautiful in these latest track photos. Liking the design details and the shocking stance more and more.
Not ‘stance’ in a tuner sense — more like physically sucking itself into the tarmac. Sparking along the racetrack at max attack!
