Mother Earth’s friends may not like it, but GM’s full-size SUV trio is largely dominating the segment. The Chevrolet Tahoe offers a choice of three engines including a pair of V8 units (5.3 litres with 355 horsepower and 6.2 litres with 420 horsepower) and a turbo-diesel inline 6 (277 horsepower). There’s a Tahoe RST Performance packing 433 horsepower, too. This model benefits from upgraded brakes and suspension.
