Difference between BMW 535 and BMW M5?

Question

I mean, suppose I've bought the 535, what can I add to reach it to an M5 ? Performance/environment-wise..

Answer 1

535 has a 3.5 v6 engine making around 270hp
m5 has a 5.0 v10 engine making 507hp.
i know that stock factory m5 body panels will fit any 5 series body.
as long as the performance goes, i know there are many hamman, alpina and acschnitzer performance toys to play with. the easiest thing for you to do is the exhaust. everything else will cost you more money than your 535 itself.

my best suggestion for you - get an ac schnitzer or hamman body kit (it was originally designed for m5 but will fit your 535)
and then get hamman or ac schnitzer exhaust.

it will look great and the exhaust will add 20 more horses to your car and will sound better than m5.

haha

Answer 2

Looks like we have answerers all over the radar screen (BMW has Inline 6 or I-6; never made any V6 engines).

Here're the specs of the E60 535i vs M5. As listed on www.bmwusa.com.

535i has an INLINE 6 Twin Turbo 3 liter engine producing 300hp.

M5 has a V-10 (normally aspirated) 5 liter engine producing 500hp.

Engines aside, the two cars are built very differently even though they look similar externally; which explains why the M5 costs is some $30k+ more than the 535i - both cars at base price.

The use of twin turbos instead of a bigger engine means the 535i benefits from a lighter weight of 3660lbs while the M5 hits 4012lbs.

This allows the 535i (with a 200hp handicap) to manage 0-60 in a very respectable 5.6 seconds while the M5 does it in 4.5 seconds.

There is really no point in trying to save a few bucks by buying a 535i when you really want an M5. The M5 is a completely different car in terms of transmission, brakes, suspension, drive train...etc. If you took the time and money to upgrade the 535i, you might as well just fork out the extra money for the M5.

You also have to understand that the 535i engine is already turbocharged (ie; it's already on steroids). You probably could still tweak the pressure a little, change the ECU programming, the usual intake/exhaust mods to squeeze a little more power from it. But even if you really succeed in getting 500hp out of the 3 liter engine, it will probably not last very long without problems. So in the end of the day, you could end up killing the 535i by trying to make its 3-liter engine perform like the technologically advanced 5-liter engine.

The M5's engine is special because there aren't many cars with normally aspirated engines that can produce 100hp per liter displacement. In fact, comparing just engines alone, you can probably have a lot more room to play for increasing the M5 engine's performance than the 535i's.

As for getting a 535i to look like an M5 cosmetically, that's the easier part.

Answer 3

Try vishnu performance ECU and upgrading turbo if its the new 535i but honestly an M5 is a completely different machine. The suspension is different and body parts. Also brakes alot quicker you would be better off buying an M5 and you would save alot more money.

The poster could have the new Turbo 535i which akes about 300 hp. With a Vishnu Ecu mod + exhaust he could be in the 400 HP range easily but it still wouldnt be an M5 or have the same driving experience.

Answer 4

That's quite a task. I have a 2001 M5. The '01 M5 has a 5.0 liter V8 that produces approximately 400 hp. The BMW 535 has a 3.5 liter V8 producing about 240 hp, depending on the year. The M5 is built for performance and has upgraded suspension and transmission, in addition to the motor. Given that you are referring to the 535, I'm suspecting that you are not in the USA. The 535 was not imported during the E39 series.

The E39 M5 suspension shared its basic aluminium-intensive MacPherson strut/multi-link design of the V8 E39 5 series. However, several changes were made by BMW M. Reduced spring height, 0.9 inch (23 mm) lower. A specific shock valving, thicker front and rear anti-roll bars, polyurethane auxiliary springs and steel balljoints.

Like all V8-powered E39 models, the E39 M5 was equipped with a recirculating-ball steering system. Overall steering ratio was reduced to 14.7 from 17.9 it featured a servotronic vehicle-speed-sensitive power assist that provides two levels of resistance controlled via console mounted Sport button. The Sport button also adjusted the electronic throttle butterflies for faster throttle response. The E39 M5 is equipped with four-wheel vented disc brakes measuring 13.6" in diameter in front and 12.9" in diameter in the rear. On European-specification models, the rotors are of a "floating" two-piece design for reduced risk of cone distortion. Their lower unsprung weight improves ride quality and traction on bumpy surfaces as well. Anti-lock brakes were standard.

Answer 5

Change suspension, change transmission, change differential. You will have to squeeze about another 100 horsepower out of the engine somehow.

The M5 is more than just the engine when it comes to performance. The whole car is designed to help it perform better.
