The Audi R25 was Audi's entrant in the 2008 LA Auto Show Design Challenge.
The R25 is designed for the 2025 Los Angeles round of the ALMS. The theoretical future racing series incorporates innovative features never previously seen in any form of motor sports, such as high-velocity banks and tunnels, which allow cars to race "inverted" and the opportunity to pass anywhere with aerodynamic racecars. All top sections of the tunnels and banks are also WiTricity wireless electrical charging zones, which encourage the drivers to utilize these free energy zones instead of fuel stops.
The Audi R25 is designed to utilize and excel in this new racing environment, with features such as:
- The new Dynamic Space Frame, allowing much greater degree of flexibility, integration of circuits and rigidity
- Algae bio fuel for endurance and electric motor capability through Wireless power transfer technology
- Audi Design: Staying true to the "Form is Function" philosophy, there is not an ounce of needless element in the R25, which incorporates advanced technique and efficient form management into one. The car also uses: active micro-control surfaces which optimize airflow during the race; Man Machine Interface, which inputs all vehicle data output into the driver's helmet visor; all-around vehicle dynamic sensors and integrated on-board HD cameras with real-time data links to allow for spectator interaction, allowing fans to virtually "sit" and experience the race in any racecar through monitors and virtual reality booths.
McLaren’s new 650S model now comes in three flavors, the standard road going 650S, the competition-spec 650S GT3 for serious racers, and now there’s the 650S Sprint which is aimed at track enthusiasts who still want a little bit of comfort. The 650S Sprint also replaces the MP4-12C-based 12C Sprint as McLaren’s track toy for the super-rich. Compared to the road model, the 650S Sprint features increased downforce and better cooling airflow to the 3.8 litre twin-turbocharged V8. It also features a competition-spec fuel tank and quick-fill cap, a larger radiator borrowed from the GT3 car, a new hood with additional cooling ducts for the radiator, front wing louvres for improved airflow, reduced ride height and recalibrated damping and spring rates, 19-inch center-locking race wheels with either Pirelli slicks or wet tires, onboard air jack system, and an upgraded braking system. On the inside the McLaren 650S Sprint features a stripped-out design with a FIA-approved rol...
