AMG公司 是一家專業的改裝廠商。由當時的 Daimler-Benz 的員工 Hans-Werner Aufrecht 和 Erhard Melcher 於 1967 年在德國所創立。後來公司的賽車研發部遷往 Affalterbach 。Mercedez-Benz在1999年收購了AMG公司，使其成為賓士車的改裝車分部。AMG同時提供引擎給Pagani Zonda超級跑車，這引擎是來自於M120 7,291cc V12 汽缸(最早使用於SL73 AMG)。這款M120自然進氣的引擎現在專屬於Pagani使用。現在AMG則是Mercedes-Benz御用改裝廠。

What is horsepower?
· What horsepower is not is how much power your engine makes at high rpm… engines make horsepower everywhere within their operating range. Horsepower numbers are typically quoted at high rpms because the horsepower number is bigger than the torque number above 5,250 rpm and everyone wants to talk about the biggest number they can.

- A short test drive of any SMG car is not an accurate measure of how the car will feel over time. SMG's are entirely new and need to be driven in a way that is entirely different than what you are probably accustomed to. Most SMG owners learn over an extended time (30 days or longer) how to shift the car properly. It has a steep learning curve. Your brain needs time to "reprogram" the timing of everything, etc.
- Because the SMG has an "automatic mode," many people compare this choice to the Steptronic transmission. This comparison is not an equitable one. It is more equitable to compare the SMG to a traditional manual that has a clutch pedal. If you are traditionally a buyer of automatics because you do not like to shift, you may be disappointed with the SMG. If you are traditionally a buyer of manuals, you may find that the SMG far exceeds your expectations but only after owning it past the individual learning curve.
- In addition to upshifting, SMG's need to be downshifted by the driver (as opposed to allowing the SMG to downshift automatically because of impending strain on the drivetrain) to reach optimum performance and satisfaction. Just like driving a manual transmission, you need to keep the car in the proper gear relative to the vehicle's speed. The SMG will execute downshifts flawlessly by "blipping" the throttle to the required RPM before engaging the lower gear. In other words, it executes a perfect "heel and toe" downshift every time. This process prevents the car from becoming unbalanced and reduces the possibility of a loss-of-control situation. It's the downshifts that truly differentiate the SMG from both the traditional manual and the automatic transmission choices!
