The engine is powerful and willing and revs to the moon. The slick new double-disc clutch and six-speed transmission are race-quality. The big, fat, sticky tires tell the chassis what to do next. The onboard electronic systems evaluate conditions 200 million times per second so that the car knows exactly what to do next as we tackle this track together, lap after delicious lap, until we are waved in and our track session is ended.
We've driven all of the previous M3s, but we've never experienced this level of acceleration, braking, steering and handling in an M3. There's something very different about the way this M3 behaves, and most of that difference is under that newly domed hood.
While all three previous M3s were powered by either inline four- or six-cylinder engines, the 2008 version is the first M3 ever to use a V8 engine. It's a 4.0-liter 32-valve, 414-horsepower all-aluminum masterpiece that shares much of its design and componentry with the 5.0-liter V10 engines used in the bigger, more expensive M5 and M6 performance cars. It makes a whopping 22 percent more power than the last M3 engine.
The new V8 features variable valve timing on both intake and exhaust valves (which BMW calls Double VANOS), and unlike most V8 engines, it uses eight individual throttle assemblies, like racing engines, controlled by drive-by-wire electronics.
This is the highest-revving BMW production engine ever built, revving up to a maximum of 8400 rpm, and it makes maximum power at 8300 rpm. Maximum torque is 295 foot-pounds. BMW says it will take the new lightweight coupe form 0-62 mph or 0-100 kilometers per hour in just 4.8 seconds, topping out at a limited 155 mph. The engine weighs some 33 pounds less than the smaller inline six-cylinder engine it replaces. To make sure than the engine always has the lubricant it needs under acceleration or braking, it has a forward oil pan and a rear oil pan.
Underneath the carbon-fiber roof panel and the slick new bodywork, there is a brand new chassis and suspension system, a lightweight suspension featuring MacPherson strut front suspension, lightweight five-link rear suspension, and one of the most wonderful, linear and responsive power steering systems we have ever used. The differential has a locking feature than can transmit up to 100 percent of the available engine power to whichever rear tire has more traction. The tires are special M3 versions of the Michelin Pilot Sport, P245/35ZR-19s on 19-inch alloy M wheels.
The huge ABS brakes, 14.2 inches front and 13.8 inches rear, feature iron rotors and aluminum hubs, with ventilated discs all around, and a unique brake energy regenerating system, usually found on hybrids, that uses the brakes to charge the battery and shuts off the alternator during acceleration and cruising. There's an optional competition brake system that's even more powerful than the standard brakes.
The new M3 also brings with it an ideal 50/50 front/rear weight distribution, and a host of electronic chassis systems including traction control, dynamic stability control, cornering brake control, a start-off assistant to keep the car from rolling forward or back on grades, a driver's choice of three different shock absorber modes with the optional EDC system. If desired, the dynamic stability control system can be disabled completely for track events. M3 offers two different power steering assist modes, selectable through the iDrive button on the center console.
Speaking of buttons, another available option for the M3 V8 is MDrive, a standard feature on the M5 and M6 cars. MDrive allows the driver to preset all of the engine power, steering, shock absorber, dynamic stability control and other systems so that the M3 can be transformed from a boulevardier to a near-race car at the touch of a single button.
