You’ve decided you want to get a BMW, but you hate slow cars. Maybe you’re just interested in learning more about BMW “M” cars. Either way, you’ve set your heart on an “M” car. But which one is better for you; the M3 or the M5? It really depends on what you want out of the car. Do you want a luxurious car that can also tear a Mustang to shreds? Or do you want a luxurious car that will destroy nearly anything on a race track?
Let’s dive in, and compare the BMW M3 vs M5. For this comparison we’ll mostly look at the F80 M3 and the F10 M5.
BMW F80 M3
When BMW released the E90 M3, BMW enthusiasts across the world were outraged that it didn’t come with an inline-6 engine. Although the E90’s engine was absolutely awesome BMW returned to its roots with the F80 M3. Unlike inline-6 BMW’s before it, the F80 came with two turbos strapped to the engine. This increased power output to 425 horsepower and 406 lb-ft of torque. This made the F80 the fastest M3 by far. It’s actually comparable to the C7 Corvette Z06 in terms of performance.

BMW F10 M5
Unlike the M3, the M5 isn’t nearly as talked about amongst the car community. This is probably because its designed for the “older” crowd and I don’t fit into that demographic. The M5 has come with a host of different engines over the years. Everything from inline-6s, to v8s, to v10s. The F10 M5 is equipped with a twin turbo V8 that outputs a ridiculous 560 horsepower and 502 lb-ft of torque. This is 60 more horsepower and 122 lb-ft more than the out-going E60 M5 with it’s V10 engine.

M3 vs M5: Size
If you know anything about the BMW numbering system than you’d know that the larger the number, the larger the car. So it should come to to surprise that the M5 is significantly bigger in size than the M3. The F80 and F10 are no exception to this.
Here are the dimensions of the F80 M3:
Wheelbase 2,812 mm (110.7 in)
Length 4,671 mm (183.9 in)
Width 1,877 mm (73.9 in)
Height 1,430 mm (56.3 in)
Curb weight 1,595 kg (3,516 lb)
Now here are the dimensions of the F10 M5:
Wheelbase 2,964 mm (116.7 in)
Length 4,910 mm (193.3 in)
Width 1,891 mm (74.4 in)
Height 1,451 mm (57.1 in)
Curb weight 1,945 kg (4,288 lb)
As you can see from all these numbers, the M5 is larger in every dimension. Most notably it’s 10 inches longer overall, which is mostly used for increased rear leg room. The cost of this increased size in a much larger curb weight. The M3 is over 700 lbs lighter than the M5.
M3 vs M5: Price
BMWs are most definitely on the pricey side. They’re luxury cars, so you should be expecting that. “M” cars take that to the next level. After all, performance parts aren’t cheap. The F80 M3 starts at $63,500 for a “base” model, and with options it can quickly climb above $80k. The F10 M5 starts at $94,100 for a “base” model, and with options can easily climb above $120k.
What do you get for that extra $31k? Well, you get a much larger vehicle over all, with much more rear leg room. The M5 is also more luxurious, more prestige, and has more power. But is that really worth $31k more? In my opinion no. If you have a family than the M5 might be slightly better, but there’s no reason 4 adults can’t fit into an M3.
M3 vs M5: Performance Numbers
If you’re a die hard car person, than this is the part you been waiting for. What are the numbers? After all, numbers can tell you a huge amount about a car. Let’s look at some numbers for the F80 M3:
- Displacement: 3.0L Inline-6
- Horsepower: 425 bhp @ 7,300 RPM
- Torque: 406 lb-ft @ 5,500 RPM
- Weight: 3,351 lbs
- 0-60: 4.0 seconds
- 1/4 Mile: 12.0 seconds @ 119.3 mph
- 60-0: 99 feet
Here are the same numbers for the F10 M5:
- Discplacement: 4.4L V8
- Horsepower: 560 bhp @ 6,000 RPM
- Torque: 502 lb-ft @ 1,600 RPM
- Weight: 4,123 lbs
- 0-60: 3.7 seconds
- 1/4 Mile: 11.9 seconds @ 122.4 mph
- 60-0: 110 feet
To my surprise these cars are actually very similar in their performance numbers. I thought the M5 would be way faster in the 1/4 mile due to its increased horsepower and torque. I guess that extra 700 lbs it has to lug around really slows it down.
Which One Is Actually Better?
After all this information i’ve given you, which one is actually better? If you ask me the F80 M3 is better than the F10 M5. The M3 is way cheaper, and just as fast. On a race track it’s way faster than the M5 due to it’s massive weight advantage. Unless you have a large family, than the M3 is way better than the M5.
