Mercedes-AMG Says Goodbye to V12 Propulsion


The V-12 engine has been part of the automotive industry since 1913.  But car guys who fancy cars with V-12 engines under the bonnet have their choices growing smaller by the minute.


Just recently, at the New York Auto Show to be exact, Mercedes-AMG boss Tobias Moers expressed that he felt engines with a dozen bores aren’t necessary anymore. Because when you can extract 630 bhp from Mercedes-AMG’s 4.0-liter twin-turcbocharged V8 in the new AMG GT 63 S saloon, AMG’s own 5.5-liter twin-turbo V-12 becomes irrelevant at ‘only’ 621 bhp. More so, now that a V8 shaves a significant mass over the front wheels, 627 lb-ft of torque is more than enough shove to get the car moving fast versus the massive V12’s 738 lb-ft.

Another great improvement would be felt in handling. The nose of the car carries less weight and that translates to more neutral handling, more flick-ability; exit corners at faster speeds. One example of note is tha Aston Martin DB11 V8 which uses the same engine as the C63 S. The V8 DB11 tackles corners better and is actually faster around a circuit even though it gives almost 100 bhp to the V12. Also, costs will lower as the V8 is shared across the AMG line-up. It also goes without saying that going from V-12 to V-8 will save the end user precious gas money.


However, this is not to assume that all V-12 power plants will be discontinued in other Mercedes-Benz models. The Mercedes-Maybach S650 may still be powered by a warbling V12, but what Maybach isn’t?


When asked, the reason Moers built the AMG GT four door is that their customers are wanting for more performance and exclusivity. And this came from owners of C63’s and E63’s. Without anything on the table – that is, until now – AMG is losing money to the BMW M6 Gran Coupe or the more exclusive Alpina B6 S.


The most interesting bit of information Mercedes-AMG head Tobias Moers shared is that the reason the AMG GT 63 S has more power than the AMG GT S is weight. It has four doors and AWD as opposed to the latter’s two and RWD.
