Because of technology advances, many four cylinder engines are more powerful than V6s from only a few years ago. For example, today's Hyundai Sonata midsize car has a 2.4-litre four with 198bhp, 45 more horses than the base V6 in a 2006 Ford Taurus. -- PHOTO: HYUNDAI MOTOR
DETROIT (AP) - Back when petrol was cheap, Americans bought cars with V8 engines like the Big Block, Cobra Jet and Ramcharger. Acceleration was all that mattered, even in family cars that never made it to full throttle.
The 6,997 cubic cm Chevrolet Tri-Power was the siren song of the gearhead, sending Corvettes roaring down the highway at up to 225kmh.
