Beginning in model year 2002, General Motors will build full-sized sport utility vehicles with flexible fuel capability at no extra charge to customers. 

The carmaker said all Chevrolet Suburbans and Tahoes and GMC Yukons and Yukon XLs equipped with 5.3 liter V8 engines will be capable of operating on varying blends of ethanol and gasoline -- from 100 percent gasoline up to a maximum of 85 percent ethanol and 15 percent gasoline, known as E85.

Beginning in 2003, the all-new Chevrolet Avalanche -- an ultimate utility vehicle -- will also have E85 capability. 

These vehicles will join the Chevy S-10 and GMC Sonoma small pickups with E85 compatible 2.2. liter engines that have been on the market since 1999.

According to General Motors, by the end of model year 2004, the automaker will have produced more than one million flexible fuel trucks.
