The drive train channels the power of the engine through the transmission unit and differential to the Front Wheels. Historically, these fall into three categories: Front – engine transversely mounted/ Front – wheel drive, Front – engine longitudinally mounted/ Front-wheel drive and Front Mid-engine/ Front – wheel drive. Most modern front – wheel – drive vehicles feature a transverse engine, rather than the conventional longitudinal engine arrangement generally found in rear-wheel-drive and four-wheel-drive vehicles. A London based after – market tuner called Auto delta has his “bored out” version of the Alfa Romeo 147 GTA which holds a 3.7 – litre V6 and churns out 328 bhp (245 kW) of maximum power and also a split – axle differential gear for the front wheels. This tuner also has made a Rotrex supercharged version producing 400 bhp (300 kW). However, the 1970 Oldsmobile Toronado remains the most – powerful front – wheel drive ever manufactured till day, with W – 34 option making 400 hp (298 kW) of power. The Cadillac Eldorado, with front – wheel drive was introduced in 1967 and holds the record for the largest front – wheel – drive in a production vehicle at 8.2 L (500 in³), starting with the 1970 model which lasted until the 1976 model year. A production Dodge Neon SRT – 4 from RaceDeck Racing was used to break the land speed record for its class at Bonneville Salt Flats in Utah on August 16, 2006. It was driven by Jorgen Moller Jr. and he set the record at 221 mph average speed for both runs on the five mile course.
