The 2007 Alpina B3 Biturbo Coupe holds an edge across most measurable criteria, offering more power, quicker acceleration, higher top speed. That said, the 1986 Mercedes-Benz 560 SEC W126 brings its own distinct appeal and remains a compelling choice for enthusiasts who value Mercedes-Benz heritage. The right pick depends on whether you prioritize specifications or the intangible qualities that make a car truly special.
The 2007 Alpina B3 Biturbo Coupe and 1986 Mercedes-Benz 560 SEC W126 stand as two of the most notable Grand Tourer cars from Modern classic. Both emerged during a period of intense competition, and choosing between them remains a passionate debate among collectors. The 2007 Alpina B3 Biturbo Coupe holds a clear advantage in raw power with 360 hp compared to 300 hp, a 60-horsepower difference that shapes the driving experience. Under the hood, the contrast is notable: the Alpina B3 uses a Inline-6 Twin-Turbocharged displacing 2,979 cc, while the Mercedes-Benz 560 SEC relies on a V8 SOHC 16V with 5,547 cc. In the sprint to 60 mph, the 2007 Alpina B3 Biturbo Coupe edges ahead at 4.7 seconds versus 6.3 seconds. The Alpina B3 carries a weight advantage, tipping the scales 441 lbs lighter. Rarity plays a significant role here — with only 800 units built, the 2007 Alpina B3 Biturbo Coupe is considerably scarcer than the Mercedes-Benz 560 SEC's 28,929 examples. Both trade at comparable values on the collector market, making the choice between them largely one of personal preference.
