i barely get past 300km on a tank on my e92, and about 340km on the ISF

Are the tank sizes the same?

Wow. I can't believe you guys DD these cars. I don't know why the gas tanks aren't larger. I would be so annoyed having to fill up every 3-4 days.

I only get like 380km per tank in the city in my e36 with just over half the power of these cars. If you aren't doing any highway driving, it takes you like 2 weeks to drive 300km in the city, since you can never get any faster the like 15 fucking km/h.
I'm sure if these guys were able to actually cruise it wouldn't be that ridiculous.

Haha I'm glad I'm not the only one.

I do like 100% city driving. Multiple 5-10 min drives a day. Occasionally go to Van or BBY on the weekends. That's usually when my mileage improves.

I think my car has a 67L tank.

I think pretty much the same, both are about 64L capacity

I'm pretty much 100% city too, don't ever get on the highway much unless i head out on the 91.

The ISF has that nice engine note and the fastest torque converter automatic, and the sound it makes when you downshift getting ready for that exit ramp is pretty addicting. The M3 just feels more direct and nimble, turning is much sweeter in feel than the ISF

I have my 6 speed manual 2016 M3 for 8 months and love the versatility of it and it's Jekyll and Hyde personality. I can drive casually and because of it's high torque at low RPM's I can easily drive in 5th or 6th gear around the city and usually get around 500 km on it's 60L gas tank. On the other hand if I want to have some fun I can press the pre-programmed M button and drive with more aggressive throttle, suspension, steering, and traction control settings. On the highway cruising at 100km per hour in 6th gear my M3 goes through 8L of gas per 100 km.

Insurance on my M3 is only $1,450 per year which is almost the same as it was on my 2013 BMW 335 xdrive. Backseat room is also great! I am 6'2" and with the driver seat set for me I can easily sit in the seat behind the driver's seat. I have had 5 passengers in my M3 probably more than 10 times and have never had any complaints. I wouldn't want to take 5 passengers on a 3 hour road trip but anything up to an hour should be fine.

The sounds piped through the speakers take off at least 10 ltrs per hundo tho

having owned two of those cars........ (M3 and C63)


- gas mileage- both are almost the same (300 ish km on a tank if strictly city) same tank size

- C63 being more comfortable than my Non EDC equipped early competition coupe M3

- P30 package is a must for the C63... 1 wheel tire fire for the non Performance package cars.

- Both have their fair share of expenses. Throttle body actuator on M3 ($1700 per bank), seatbelt actuator (the thing that hands you the seat belt, need to replace seat belt assy on an older car)

C63 - possible headbolt issues (usually warrantied by now on majority of the cars) , the damned comand Control knob (they all fail after warranty, ($500 ish part + install), the front brakes (2pc rotors and the brake job from MB was $5300........ fuck) and the C63 was the one that was heavier on the rear tires........


Both are entertaining in their own ways...... M3 being the more precise and rewarding car to rev up and the C63 being an over powered Four door sedan that is no different from a Muscle car.....


Drive both and do a longer drive and see which one you like better!

Rod bearings Rod bearings Rod bearings for e9x M3s

"S65 has the second worst clearance to journal size ratio, and by far the worst RPM to Clearance ratio. It's pretty clear that for whatever reason, the S65 sticks out like a sore thumb in this list."

It is so bad there is a class action lawsuit on BMW for the S65.

C63 , love the raw 6.2 v8

How much is it to fix that seatbelt actuator? Mine still pops out but never hands me shit. I have to start driving so it retracts before I reach my arm all the way back to grab it. What a horrible design.

I believe they fixed that issue on 2011+ models

do you live in BC? How is a brand new M3 insurance under $1500 annually?

$3500 annual for me @40% discount.


AMG was closer to $2800 annual @35% discount. Fml.

I think they made adjustments but did not actually fix it permanently

I think he means brand spanking new 2015/2016

Dont think so...... I also do know a newer M5 is quite steep as well..... :alone:

Sounds like they're both typical German money pits.

Mines $2750 a year full discount, and yea they never fully solved the problem of the rod bearings, just changed materials in 2011 that slight improved wear but not much

I think it was like 6.7g for new M4 and 7.5 for the new M6 without discount IIRC.

E92 M3 quote i remember was a hair over 7k with 0 discount :alone:


@underscore: nice things costs money. it ain't free lunch.

I had an E92 M3 and now this spring bought a E90. I came back to the M3 after looking at the C63 and ISF, the other two just didn't do it for me. Plus the M3 is the only one that comes with a manual. Sure it feels a little under powered in the city but out of the two its by far the most nimble. Other two didn't feel sporty enough to me. The C63 tq was great but it felt dull, like driving a tank.

Even when I don't drive sensibly I still get close to 400km/tank in the city with a 55L fill up. Close to 500 highway. Change those plugs. ;)

You can get plenty of nice things that don't cost an arm and a leg to repair poor engineering, and can you really call it nice when you know a bunch of expensive things are going to fall apart?

Engine in E90/E92 M3 = Rod bearing issue = defect
Engine in C63 before 2012 = Headbolt issue = defect
Engine in Porsche 911/boxster/Cayman before 2009 = IMS issue = defect

All these have engine killing defects but people still love them, myself included! Shows how emotions trumps over being rational.

I have 25 years safe driving with the maximum discount for my 2016 M3. I also have my optional insurance with Canadian Direct Insurance and a multi vehicle discount with CDI. I think the quote I got for the same insurance through ICBC for my full insurance for my M3 was around $1,900.
