Jeep has made the 4.7 litre V8 (petrol) engine (162 at 4700r, 390 at 3200ropm) available, as an alternative to the straight six, in the base Laredo Jeep Grand Cherokee. The V8 comes with the `45RFE' 5-speed automatic gearbox. The `Quadra Drive' four wheel drive system, i.e. the Quadra-Trac II transfer case with front and rear Vari-Lok LSDs, is an option. The Quadra Trac transfer case drives the rear wheels normally, but if there is wheel slip a pump raises hydraulic pressure to a multi-disc clutch thus sending drive to the front axle.

      Ford acted as second supplier of the Willys Overland design which won the Army's contract for a light four wheel drive. After the war, Willys took the word `Jeep' as a trade-mark which must have been a sore disappointment to Ford!
