The American based Auto Marquee called General Motors has recently partnered with International Cars and Motors Ltd (ICML). As a part of its venture, the firm will come out with a BS 4 compliant Tavera by early next year. There are speculations that the BS 4 engine that will power the Tavera can be upgraded to BS 5 as well. The engine will be a 2.0 litre CRDi engine which will now make the car a tad more powerful and a bit costlier too. This BS 4 compliant Chevrolet Tavera is expected to be launched by January 1st, 2011.
