Spy Shots of the upcoming Besturn B50 RS testing in China, featuring an aggressive body kit with a big wing on the back. The B50 RS is the sporty version of the upcoming facelifted Besturn B50 sedan. The facelifted B50 and the B50RS are expected for debut on the Chengdu Auto Show in September.

This is the current Besturn B50. Price starts at 92.800 yuan and ends at 122.800 yuan. Two engines: a 1.6 with with 106hp and 145nm, mated to a five-speed manual or a four-speed automatic, and a new 1.8 with 139hp and 172nm, mated to the same six-speed automatic.

Besturn is a brand of FAW, First Auto Works. The Besturn B50 is based on the old Mazda 6 that is still in production by the FAW-Mazda joint venture, and the 1.6 liter engine comes from the Volkswagen Bora which is made by the FAW-Volkswagen joint venture.

Besturn test drivers are a messy bunch. Sporty red stitching barely visible under cheap after-market seat covers. The RS is a new addition to the Besturn B50 line-up. It will also get a ‘new’ engine: a 1.4 TSI with 131 hp, sourced from Volkswagen, which is using the engine for various models manufactured by FAW-Volkswagen.

That wing is truly impressive, the engine is good, and the market for sporty cars is growing fast. But will that be enough to convince eager car buyers to get a Besturn..?
