Echoing the same and raising the bar: if you could lease this car for $199 per month (including tax), would the experience overshadow any perceived shortcomings?

I don’t see any short comings in an x5 driver LOL I know all about heavy vehicles

Also it looks pretty too, I’m not sure where the visual hate comes from either!

Agree.

It’s absolutely gorgeous in the flesh too.

[QUOTE="IMS-340C;31708723"]Incredible car, just needed 100 HP more from factory

…which it does …if the dyno data is correct!

regardless of design, slowpokes shouldn't clog up the L hand lane. Europeans are great about only using the LHL for passing and yielding to faster traffic.

Driving an M5 w/o the increased speed limiter on the Autobahn is anticlimactic to say the least.

Yep. But it would be even more sad if they imposed speed limits everywhere on the autobahn.

We’ve done ED and I’m well aware of how terrible US drivers are.

Well, it's getting worse every year anyways. When I used to live in Germany many moons ago, the amount of the unlimited speed sections was almost double of what there is today. Today, they have less than a fifth of the existing autobahn network unlimited and most of the sections that are unlimited are the busiest ones. So, in order to really enjoy an unlimited drive, you need to be out in the middle of the night anyways.
Besides, the issue is probably not the CO emissions but rather the additional money the government is going to make from the hefty speeding tickets they'd issue as anywhere else in the world.

Still, the interior dashboard is horrendous... The exterior is also a big let down... Nice Camry though

This is the most likely technical reason. While simple math would say the combination of the S68 and hybrid motor should yield more than the stated power and torque figures, the reality is that the ICE power and torque curve peaks are different from the electric motor so it's not simply additive, but something less. Add in that the transmission must handle all that power and torque reliably for well beyond the warranty period. If BMW wanted to give us more, then it would have required a stronger, heavier transmission. They likely detuned it to reach the 1000Nm peak and reliability testing between ZF and BMW determined this was the best compromise.

I 1,000% agree. If you look at a dyno graph it looks just like what you see with large electric motors and industrial equipment.

From 0 RPM and up you have a very flat torque curve so as not to overload any particular component. Once the RPM’s increase and things start to heat up, the system switch to constant power where torque slowly decreases as RPM’s increase. On the M5 this happens about 5,250 RPM’s

The power curve on the G90 M5 looks exactly like what what you would see to protect a drivetrain component.

Due to parasitic loss the wheel output will always be lower that the crank HP/TQ, hence the difference in the Dyno compared to the stock figures.

What does that translate into actual HP/TQ, and whether it can be tuned to match for example F90 engine to exploit any loss in HP/TQ from factory?

That makes sense, but what if the battery is depleted and no power off the electric engine why bmw don’t have the v8 maxed out like any m car? All that fuss for an 18kwh battery that wont last like 40miles?

Average parasitic loss is about 15% across all brands, in this case it’s about ~75-100 HP/TQ on the M5.

I don’t think the S68 ECU has been unlocked yet so it’s unlikely you’ll see custom tunes for a bit, to my knowledge the S68 makes about the same power as the S63, in the low 600’s from factory.

I’m not here to defend the hybrid setup, just trying to understand it. Last week I drove the G90 M5 and G60 550e back to back at my dealer. My understanding is, the hybrid battery will never deplete completely that you won’t have full power available. IOW, if you drive in electric mode it will kick over to ICE mode to retain enough battery capacity to supplement full electric power to the ICE to always have maximum power available. It doesn’t regen the battery in all cases, mainly coasting or braking. That said, I don’t think I’ll be getting either car because the charging requirements don’t work for me where I live 4 months of the year so pure ICE only for me.

No guys the reason BMW limiting G90's power is not Gearbox torque limit.

You can easily increase HP significantly without increasing torque.
