The 2013 F10 M5 with its 4.4L V8 S63Tu turbo engine has previously been shown to be underrated from the factory, which is BMW’s habit with its official quote power figures.
The latest results showing this come from iND who have just begun performance testing on their F10 M5. The result was 527 RWHP (rear wheel horsepower) on a totally stock F10 M5 running on pump gas and dyno’d on a dynojet. This represents just a 6% drivetrain loss.
The M5′s S63tu V8 runs a higher compression at 10.0:1 (@ 22 PSI), compared to the X5M/X6M S63 engine’s 9.3:1 (@ 17 PSI).
As announced yesterday, BMW’s N20, N54, S65, N18 engines have each picked a best engine award at the 2012 International Engine of the Year Awards [Full Award Results].
Here’s a brief overview of two of the technologies featured in most of the BMW engines available today – TwinPower Turbo and VALVETRONIC (variable valve timing) technology. Valvetronic was first introduced by BMW on the 316ti compact in 2001, and has since often been coupled with BMW’s double-VANOS.
Until 2012, no M model used Valvetronic, but instead continued to feature multiple throttle-bodied designs. The 2012 F10 M5 with its S63 engine is the first M model engine to utilize Valvetronic technology in lieu of the individual throttles found on its equivalents in the BMW X5 M and X6 M. The … CONTINUED
Manhart Racing has unveiled its new MH5 S Biturbo tuning program for the BMW M5 (F10).
The first stage tuning package breathes more power into the M5′s bi-turbo 4.4L V8 S63Tu engine by pushing it 624hp (633 PS / 466 kW) and 575 lb-ft (780 Nm) of torque. This is an increase of +72hp (73 PS / 54 kW) and 74 lb-ft (100 Nm) over factory.
Yet to come will be even more powerful stages which will produce 661hp (670 PS / 493 kW) and 725hp (735 PS / 541 kW). Full details are not yet released, but you can bet on changes to the F10 M5′s turbochargers, downpipes and exhaust system to achieve these monstrous figures.
As for other performance upgrades, Manhart will offer an adjustable coilover suspension … CONTINUED
Since its recent European market introduction, many a M5 fan has been waiting to see the tuning potential of the new F10 M5 and its beefy 560hp bi-turbo S63Tu engine. The first F10 M5 ECU tune has now been released, by the German tuning company, PP-Performance.
They were recently able to crack the factory ECU and their Stage 1 tune added:
Gains: +60hp and +70Nm (51lb-ft) torque
New total output: 620 HP / 750Nm (553lb-ft) torque
The price for the stage 1 tune has been set at 3,499 € (euros). Their Stage 2 tune is already in the works, so expect even higher modified numbers from the F10 M5 soon.
With tuners already achieving 750hp with the S63 motor from the X5M/X6M (such as the Manhart biturbo M3), expect the same … CONTINUED
We’ve all seen plenty of photos of the new 2012 M5′s imposing biturbo V8 S63Tu engine, which produces a whopping 560hp. But what exactly are we seeing when we peek under the hood of the F10 M5? Here is an explanation of some of the components seen on the S63Tu engine, as well as how they work together.
As we reported earlier, the engine of the F10 M5 isn’t a direct swap from the X5 M and X6 M but a substantially revised engine. In an interview with M-Power.com, Jürgen Poggel, Head of Engine Development at BMW M GmbH, now shared more details on this engine. Read the full interview below to learn more about the newly introduced VALVETRONIC, the principle of the cross bank exhaust manifold and more. An interesting tidbit: Unlike earlier M engines, the S63TU no longer needs 10W-60 oil.
Mr Poggel, what were the greatest challenges in developing the V8 engine for the new BMW M5?
Jürgen Poggel: The V8 engine is a high performance sports engine. Our goal in developing this new model was to make it even better that the … CONTINUED
What most folks have not realized so far are the extensive modifications BMW has made to the F10 M5 engine. We point those out for you below, referencing BMW’s released info. Compared to the S85 engine of the E60 M5, BMW claims that “VALVETRONIC has also sharpened the responsiveness of this engine [S63Tü].
Here are the highlights of the new M5′s S63Tu engine and how it’s different from the S63 engine used for the X5 M and X6 M.
Two more innovations of the S63Tü:
- Innovative solenoid valve injectors in the new BMW M5 engine use multiple injections to achieve an extremely precise mixture preparation.
This is the biggest difference. As BMW puts it:
“Throughout each of its four previous generations, the heart of the BMW M5 has … CONTINUED
