The Avalanche vehicles were fitted exclusively with the 5.7 litre LS1 V8 engine rated at 270 kilowatts (360 hp) of power and 475 newton metres (350 lb·ft) of torque, mated to a four-speed 4L65-E automatic gearbox. Permanent all-wheel drive was calibrated to deliver 62 percent of the power to the rear wheels, thereby maintaining a rear wheel drive feel to the handling of these vehicles. Come in and see what makes HSV so special. This is actually a part of motoring history!
