While the Toyota TS030 Hybrid won't be participating in this weekend's FIA World Endurance Championship race at Spa-Francorchamps in Belgium due to a crash in pre-season testing last month , that didn't stop the automaker from bringing the new endurance racer as a preview for what's to come for the 24 Hours of Le Mans in June. The TS030 even made time for a quick photoshoot at the infamous Eau Rouge alongside the new Audi R18 e-tron Quattro, which happens to be making its race debut this weekend.While both the Audi and Toyota employ hybrid powertrains, a first for endurance prototypes, each go about it in very different ways. The TS030 makes use of a naturally aspirated 3.4-liter V8 while the R18 e-tron Quattro uses a turbocharged diesel V6. Audi's hybrid system powers the front wheels, hence the Quattro name, while Toyota has yet to announce whether it's system will drive the front or rear wheels.The closed cockpit racers make for quite an attractive couple, and we hope it's a pairing that will form a lasting rivalry in the coming years.
