The perfect recipe for a sports sedan looks something like this: 300+ horsepower from a naturally aspirated engine, 50/50 weight distribution, excellent steering feel and precision, a rigid chassis, taut but forgiving sport-tuned suspension, great throttle response, powerful and progressive braking, room for five, good trunk space, handsome but understated design, and, of course, a manual transmission. Simple? Yes. Common? No.
But nearly 20 years ago, BMW nailed the formula with their E39 M5 (1998-2003), the reigning king of all M5s. It is a car praised for its power, performance, balance, tractability and design. Amongst the lineage of M5s, it is easily the best.
What It’s All About
The E39 M5 had great bones: the stock E39 sedan. The standard 5-Series was considered unmatched in the German sports sedan world, widely hailed as the best chassis and suspension combination of its time — with the right amount of stiffness and compliance for a ride that was both incredibly comfortable and utterly thrilling (when it needed to be).
Then, BMW Motorsport came along and made a good thing better, starting with a spectacular engine. The S62 engine had 4.9 liters of displacement from a naturally aspirated V8, based on the 545i’s M62 V8 motor. The S62 produced 395 horsepower and 369 lb-ft of torque to the rear wheels with an astounding 7,000 rpm redline. This engine was built with what’s known as Double-VANOS: individual throttle butterflies on each cylinder and variable valve timing so both intake and exhaust cams possess infinite variability and adjustment. The S62 engine, with its fat torque curve and excellent flexibility, was masterful. And it happened to be so damned good that Bimmerphiles widely consider it the finest V8 engine BMW has ever made.
