Of the three, the Audi is the least powerful but also the lightest by having a twin-turbo 2.9-liter V6 with 450 hp and 600 Nm (443 lb-ft) in a car that weighs 1,745 kg (3,847 lbs). The long-roof M3 has a 3.0-liter inline-six rated at 510 hp and 650 Nm (479 lb-ft) in a super wagon that tips the scales at 1,865 kg (4,111 lbs). As for the C63 Estate<\/a>, its big 4.0-liter V8 produces 510 hp and 700 Nm (516 lb-ft) in an AMG wagon that weighs 1,800 kg (3,968 lbs).<\/p>\n Despite its power deficit, the RS4 Avant was surprisingly quick off the line and managed to beat the M3 Touring<\/a> in the first drag race when the BMW was in RWD mode. With xDrive turned on, the high-performance Bavarian estate won in the subsequent drag races to the quarter mile by better putting the engine’s power to the wheels. The AMG C63 Estate was the slowest of the three in all drag races but had its revenge in the rolling races to the half-mile where the V8 had enough room to stretch its legs.<\/p>\n The last battle was a brake test from 100 mph (161 km\/h), with the Audi coming to a halt in the shortest distance.<\/p>\n Regardless of who won or lost that day, you can’t really go wrong with any of these three cars since they tick just about all the right boxes and then put them in that large cargo compartment.<\/p>\n Source: Carwow \/ YouTube<\/a><\/p>\n![\"\"](\"https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/2023\/01\/BMW-M3-Touring-Frozen-Portimao-Blue-4-830x553.jpg\")
