The Formula 1's adoption of a "world engine" concept is believed to have gotten the interest of Volkswagen even as its plans for technical rules in 2013 and beyond are still undetermined.
VW motorsport director Hans-Joachim Stuck clarified that the company doesn´t want to field a works team similar to what Mercedes did, with its acquisition of Brawn GP, or Ferrari.
Rather, it is merely looking for an engine supplier. In an interview with Auto Bild magazine, Stuck revealed that the company is waiting for FIA's decision with regards to the use of a world engine for Formula 1.
Stuck added that if there actually is a world engine, VW will be considering whether to build one for Formula 1. The "world engine" is an item that is not built strictly for one purpose or one form but instead, can be applied in multiple types of racing.
Speculation about the next-generation F1 engine is centered on a small (about 1.5-liter) in-line four-cylinder with turbocharger and an upgraded version of the KERS energy-recovery technology that was used in an experiment last year with the series' 2.4-liter normally aspirated V8s.
To date, none of the manufacturers participating in F1 have voiced their support for the world engine concept. Stuck's attendance of the 2009 NASCAR season finale at Homestead-Miami Speedway, further fueled rumors about a VW entry into the American stock car racing series right after Toyota.
Stuck also expressed an interest in the IRL IndyCar Series and the Grand Am sports-car series, which is operated by NASCAR's France family.
