First time caring about a hybrid vehicle:

1. The M5 starts up in electric mode, does the engine also turn on?

2. Usually, gas cars need a few minutes to warm up after a cold start before driving off. Is this the case with the new M5?

3. If I just started the car and drove off in electric mode, at what point can I start using the engine without damaging it (warm up oil etc)?

4. Is e-control the only mode that can recharge the battery?

5. Is hybrid mode the most fuel efficient?

6. The F90 startup sound is LOUD, can the G90 also start up the engine, or is it always going to be quiet?

I cant speak for the M5, but the Xm i can and as the powertain is basically the same.


1. The M5 starts up in electric mode, does the engine also turn on? No, starts in hybrid mode and motor is off until you go pass the kick down in the gas pedal,or have a m1/m2 setting. Only way it stays in ev mode is if you do ev mode only.

2. Usually, gas cars need a few minutes to warm up after a cold start before driving off. Is this the case with the new M5? Yes, when the motor kicks on its cold start, rpm redline does the change as it warms up.

3. If I just started the car and drove off in electric mode, at what point can I start using the engine without damaging it (warm up oil etc)? You can use the motor whenever you want, just know that like any car it's cold. Will take a few minutes to warm up to go ham.

4. Is e-control the only mode that can recharge the battery? This depends on market. On the XM the gas motor cannot recharge the battery in the US, but will in other places. With that your putting juice back into the car via brakes and the tranny. E-control is telling the car to not use the ev side.

5. Is hybrid mode the most fuel efficient? Yes

6. The F90 startup sound is LOUD, can the G90 also start up the engine, or is it always going to be quiet? Cold starts on all bmw's are loud..once it warms it quiets down. If you want the car to always start with the motor. You program the m button to do so, then once you get in turn the car on and hit you settings and the motor will always stay on.
