Good question but every article I could find on the Ariel Atom Aero-P completely omits any discussion of the powerplant, focusing instead on the dual electric fans it uses for on demand down force. They claim it can be visibly seen to compress the suspension when engaged and can be used for launching or cornering to significantly aid in adhesion to the track without requiring the wing/winglets and such that actually consume extra fuel by virtue of the aerodynamic drag such downforce devices use to achieve extra downforce, which also only occurs "at speed".

It's currently just a prototype but it's use of a race proven (and immediately banned!) idea is cool. Jim Halls team first ran a car utilizing this concept in their Chapparal Can Am car in 1970, but McLaren instantly lobbied for its banning from the series. Niki Lauda later ran a similarly designed F1 car, which was also banned.

In the 90s toy maker Tyco incorporated a variation on this theme by placing the electric motors magnets in their HO series slot cars in close proximity to the rails in the track thus utilizing magnetism for highly increased cornering capabilities. The track adhesion was so good they could even be run upside down. Lil bitches were also capable of 1000 scale miles per hour on long straights!
