Mercedes-AMG expands V12 engine production to Mannheim

Mercedes-AMG may be downsizing some of its engines, but it hasn't given up on making V12s. In fact it has so much demand for them, and so little room to expand, that it is opening a new workshop at another location just to handle V12s. We take that as a good sign. That new location is the Daimler factory in Mannheim, in southwestern Germany, which is already dedicated to engine production and is located just an hour and a half from the Mercedes headquarters in Stuttgart and the main AMG workshop in neighboring Affalterbach. But although the assembly of its 12-cylinder engines is being moved, it will still be carried out under the "one man, one engine" philosophy that sees each motor built from start to finish by one highly skilled and specially trained AMG technician. The move will give AMG the capacity to build more of its V12 engines. But it will also make use of excess capacity at the Mannheim plant, and allow the Affalterbach site to use the space and technicians freed up by the V12 move to focus instead on V8s. Those concerned about AMG's ability to maintain its levels of quality and performance at a remote location might note that production of its turbocharged four-cylinder engines for the A45, CLA45, and GLA45 models is already carried out by MDC Power GmbH, a Daimler subsidiary in Kolleda, using the same philosophy. AMG's current 6.0-liter twin-turbo V12 engine produces a massive 621 horsepower and an even more impressive 738 pound-feet of torque. It's used in the SL65 roadster, G65 sport-ute, and S65 coupe and sedan... and maybe soon in the S65 cabrio as well. Come to think of it, a twelve-cylinder version of the new GLS seems like a good idea, too. And though Aston Martin is contracted to use AMG's eight-cylinder engines, the added capacity could get the creative juices from Gaydon flowing as well.

Due to strong demand for its high-performance automobiles, Mercedes-AMG is to start the assembly of its 12-cylinder engines in a new location at Daimler's site in Mannheim. The traditional AMG "one man, one engine" philosophy continues to hold true: each powerful AMG engine will be built completely by hand by just one engine fitter. The employees who currently assemble 12-cylinder engines at the AMG headquarters in Affalterbach will be shifted to the eight-cylinder engine lines.

2021 BMW M3 and M4 vs all the high-powered sport sedans and coupes

Should you have a found a way to get past that schnoz, you've probably digested some of the basic specs for the all-new 2021 BMW M3 sedan and M4 coupe specs. They're plenty impressive. There's also, basically, two sets of them thanks to the regular and Competition versions that differ in engine output and transmission type.  But how do they compare to other ultra sport sedans and coupes? Well, we were wondering that too, so we fired up the Autoblog Comparison Spreadsheet Generator 5000 (aka me chained to my computer in a dark basement).  Sadly, there are surprisingly few competitors for the 2021 BMW M3. Rival sedans include the Mercedes-AMG C 63 and the Alfa Romeo Giulia Quadrifoglio, along with the Audi RS 5 Sportback sedan/coupe/hatchback thing. There's no more Lexus IS F, the Cadillac CT4 Blackwing has yet to arrive and Jaguar doesn't offer a spicy XE R.  Happily, there are more coupe rivals for the 2021 BMW M4, including the two-door versions of the AMG and Audi as well as the Lexus RC F. I also included the Ford Shelby GT350 and Chevrolet Camaro SS 1LE. On paper, they align incredibly well. On the street and on a track, I can personally attest that these Americans are fully capable of keeping up and/or bettering the fancy-pants luxury brands (and let's not forget there are even more powerful, hardcore versions available). If they don't align in terms of price or prestige, whatever. OK, let's get to the spreadsheet. Let's start with the coupes and note that I didn't bother listing the dimensions for the M4 Competition and C 63 S as they are identical to their "lesser" siblings.  I won't bother burning words explaining what you can see on the chart. Instead, I'll point out a few things that stood out to me. First, BMW M comes awfully close to matching the output of AMG's twin-turbo V8 despite having two fewer cylinders. Similarly, Audi manages to better the 0-60 time of the M4 Competition and tie the C 63 S despite being WAY down on power. It's not like it weighs less. Magic? Second, and speaking of 0-60 times, remember the importance that transmission and drivetrain make with them. It's not just horsepower and torque. An automatic will be quicker and easier to launch than a manual, while all-wheel drive provides more instantaneous and beneficial grip.

Mercedes-Benz S63 AMG officially teased in mini video

The followup to the Mercedes-Benz S550, the S63 AMG, will sport a biturbocharged V8 that will likely turn out around 550 horsepower. The new engine is probably the 5.5-liter, biturbocharged V-8 that's been popping up in everything from the ML63 to the E63 AMG. The front fascia is more aggressive, which shouldn't come as a surprise, while a meaty exhaust setup can be found out back.
We managed to pick all that up from a short, 17-second video posted by MB. The original video that unveiled the S63 AMG has since been pulled down, making this YouTube clip the best look we now have at the new super sedan, at least until the Germans give up the goods for real.
Be sure to check out the video below, along with our original posting on the S63 AMG.
