Post a pic of your Ride !!

agreed mostly, but i do think they have better engineering. what size engine is in the g8? i'm guessing a 4. something v8, which is being tested against a 3.5v6. i HIGHLY doubt the new m5 would even be close to it. 5L 500hp in m mode, i would think it would run away with ease. as far as actual engineering, i find it impressive that they can get 500hp from a 5l n.a. when most american cars go for huge displacement to make comparable power outputs.

g8 is a 6.0
gxp is a 6.2
3.5 v6? 550 is a 4.8 liter v8

M5 motor is a sweet engine, but what do you have against displacement...the v10 is rev happy and almost tuned to the max already...any small amount of tuning with the bigger engines can yeild enormous power. What's the point of a high hp per liter in a daily driver, it almost always decrease reliabity. And there is no weight advantage.

BMW's M5 Product Information Guide says that the M5's 5.0 liter 500 hp (SAE net) V-10 weighs 240 kg/529 lbs.
The 6.0 liter comes in at 448 pounds and has cylinder deactivation for fuel econ.
In fact the big block 427/7 liter ls7 zo6 engine fully trimmed weighs 458 pounds.
Kinda stupid engineering to make a smaller heavier engine.

the 535i which is compared in the skidpad is a 3.5l v6

i wouldn't say the m5s have no room left to add power. if you reworked the ecu you could put a turbo/s on it and get huge power.

i'm surprised the beamer is heavier, since all their cars are massive. but i'm guessing there is a reason they didn't make it any lighter. maybe just to balance it better

BMW calls it the DME. Digital Motor Electronics.

Ok! I know that Audi owns Lambo, My point was Lambo is still marketed as an Italian car.

haha ok good, just making sure.

BMW doesn't make a car that can out run a C6 Z06.

i never said they did, i just said american cars rely on pure speed to market them

of course they would be different.. lol

So? What does engine size have to do with skid pad? You drive in a circle until the wheels break loose.

Tuning an M5 isn't something you are going to do yourself...even pro tuning shops aren't doing much more than adding an exaust and maping the ecu for the new exaust. With more than 1,000 individual components, this engine management system is stupid complex. You aren't going to add a turbo to that thing and expect it to run.

It's heavier because it's needlessly complicated. Balance by weight? try again. It's heavier cause you have a high compression ratio and too many little pistons moving too fast, and you need metal if you don't want it to blow. But why should it matter, it's heavier and what's the advantage of less displacement if it comes at the price of weight.
It's a cool engine don't get me wrong, and has won enough awards but beyond the wow factor it isn't that practical. It winds like a bee-hive, gets 11 mpg city / 17 mpg highway? Expect them to dump the v10 in favor of a smaller twin turbo v8 at some point for fuel econ, pushing less hp. The SMG gear box has been a bit of a flop, being too clunky for many, most are opting for the no cost option 6 speed.

Zero to 60 in 4.6-4.8 depending on your source...The G8 GXP is capable of moving from 0-to-60 mph in 4.6 seconds, and can turn a quarter-mile time of 13.0 seconds at 108 mph. 13 mpg in the city and 20 mpg on the highway. Less than half the price.

Anyway bottom line is m5 is a super cool car and nobody is going to make fun of you for driving up in that...but the german engineers have a heck of a lot more money at their disposal per unit.

audi?????????? just traded in my girls a4 for a new 370.. nothing but problems with that car

****in light engines.....i think my transmission weighs much more than that
