Superlative performance for the 6 Series: the 4.8-liter Valvetronic V-8 engine
BMW 650I REVIEW
Under the 650i models’ aluminum hood is a further evolution of the technologically advanced and unique N62 V-8 engine that powered the original 645Ci models. As such, this power unit continues with BMW’s revolutionary Valvetronic system, which controls engine power by varying valve lift instead of relying on a conventional throttle. Compared to conventional valvegear, Valvetronic enhances torque, power and efficiency – and now increased displacement further boosts torque and power.
Indeed, the 650 engine achieves even greater specific power than its predecessor: with 9.1% more displacement (it’s up from 4.4 to 4.8 liters), power is up 35 hp (10.8%) from 325 to 360 hp. Likewise, its torque curve is richer; the new, higher torque peak of 360 lb-ft. (up from 330) occurs at 3400 rpm, down 200 rpm from the predecessor.
In one respect, the new engine has been simplified. The previous version had a fully variable induction system, capable of varying the induction passages’ length steplessly from minimum to maximum – certainly an optimum solution, and a very elaborate one, for achieving strong performance in all rpm ranges. With the new engine’s increased displacement boosting torque, BMW’s engine engineers simplified the induction system to 2 stages, one for low to medium engine speeds, the other for high engine speeds.
The 6 Series’ exhaust system is specially engineered to lend the V-8 engine an extra-sporty note. Actuated by engine vacuum in response to engine speed and load as well as the gear currently engaged, a movable element in the right-hand resonator is programmed to achieve the sportiest, most pleasurable engine sound within the overall legal exterior-noise limit.
6-speed STEPTRONIC automatic.
This combination of torque converter and 6-speed gearbox is plenty sporty – as demonstrated by a 0-60-mph time only a tenth of a second less quick than for the manual transmission or SMG. As with all other current BMW automatics, the S (Sport) mode moves shift points upward to higher engine speeds for sportier feel and response. The M (Manual) mode enables the driver to up- or downshift at will, imparting some of the sportiness of a manual transmission. Driver-controlled up- and downshifts are effected by “tipping” the shift lever rearward or forward.
Aluminum Driveshaft
By using aluminum, BMW engineers achieved a significant (6.6-lb.) weight reduction. At the same time, they were able to improve the vehicle’s management of impact energy in a frontal crash: both shaft sections are designed to collapse in a controlled manner under impact load. Connecting elements at the ends of each shaft section are of steel; new welding techniques were developed to weld the aluminum to the steel.
Front suspension: full aluminum, specific 6 Series kinematics
The front suspension system is a further evolution of BMW’s double-pivot front system. Its general concept and design are shared with the 5 and 7 Series, but specific characteristics, dimensions and kinematics – including the 6’s lower ride height and center of gravity – endow the 650i models with their own, definitively sporty handling and riding characteristics. Most of its components are of aluminum, which reduces unsprung weight and thus optimizes the suspension’s response to irregular road surfaces.
Key distinctions between the 6 and 5 Series front suspension (650i Coupe/Convertible vs. 550i Sedan) include:
- Stronger self-centering feel in steering
- Lower ride height
- Firmer springs and shock absorbers compared to standard 550i calibration, not quite as firm as 550i sport calibration; the 6 Series offers just one calibration, and it is sporty.
Review of the 2007 BMW 6 Series
Unlike any other car....

Vehicle: 2007 BMW 6 Series 650i 2dr Convertible (4.8L 8cyl 6M)
I looked at every "similar" vehicle - Porsche 911 and Cayman, SL-Class - but just couldn't find the right fit. I am so pleased with my decision! The car has enough "sporty-ness" to feel like a performance car, but without the harshness or diminutive stature of so many other "sports cars" (I'm 6'3" and 250 lbs). To say that it is in a class of its own is too trite, but there really isn't anything comparable. Thus far it's been a whole lot of fun. I'll let you know what long-term ownership is like.
