A DRIVE THIS INSPIRING STARTS

WITH A HIGH-PERFORMANCE PLATFORM.

When is a “sporty” vehicle considered truly

“high performance”? When every component

works together seamlessly. That’s where

the M3 shines. At the heart of the M3’s

responsive handling lies a front axle made

primarily of aluminum, including the central

subframe, the spring struts, the swivel bear-

ings, and an additional thrust plate across

the entire frame for added stability. As a result,

the front axle is not only lightweight, it’s

extremely rigid.

Redesigned from the ground up – except for a

single trailing link borrowed from the 3 Series

platform – the ﬁ ve-arm rear axle features all-

aluminum track control arms, as well as

aluminum dampers. And when compared to

construction using more conventional materi-

als, the rear axle is stiffer and 5.5 lbs. lighter.

Optimized for weight and stability, anti-roll

bars are featured in both the front and rear

of the M3’s chassis. Once again, special

engineering of the axle geometry (which

features two additional longitudinal bars)

contributes to the M3’s powerful, sporty

dynamics and road feel.

Working in conjunction with the suspension,

the M3’s ﬁ nal drive features a Variable M

Differential Lock, which provides up to 100 %

locking action for optimal traction on any

surface, in any conditions.

The suspension design allows the rest of the

vehicle’s innovative, performance-enhancing

features – from the heavy-duty manual trans-

mission to the M3 Coupe’s carbon-ﬁ ber roof

– to operate at their most thrilling capacity.

It’s the solid foundation that plays a huge

role in the M3’s unmatched driving dynamics.

Chassis I Lightweight construction

The roof of the BMW M3 Coupe is made

of carbon-ﬁ ber-reinforced material,

which is both light and very stiff.

BMW’s use of lightweight construction:

track control arms and dampers on the rear

axle are made from lightweight aluminum,

as is the load-through. The rear bumper

carrier is made of a composite material,

long-ﬁ ber thermoplastic. Perforated

compound brake discs also contribute

towards a reduction in weight.

The front bumper carriers, which are made from

composite material, and the double-joint spring-

strut front axle, constructed from aluminum, are

as important to the overall lightweight concept

as the aluminum hood.

HIGHER PERFORMANCE STARTS

WITH LESS WEIGHT, LOWER DOWN.

The M3 beneﬁ ts from lightweight construction

– in its suspension, its perforated compound

brake discs, aluminum hood, and even its

composite front fenders. But just reducing

weight isn’t enough to optimize a vehicle’s

driving dynamics. That’s why BMW reduced

weight in areas where it would have a positive

effect on driving characteristics. M-style agility

is achieved by concentrating the vehicle’s

weight as close as possible to its center of

gravity. Accordingly, BMW used carbon-ﬁ ber

reinforced material – a particularly light and

extremely rigid high-tech composite – in the

roof of the M3 Coupe, to lower the vehicle’s

center of gravity. And when combined with

the M3’s near-perfect 50/50 balance front and

rear, the advantages of lighter weight and a

lower center of gravity become obvious in

the M3’s powerful drive, high-revving pickup,

improved roadholding and shorter braking

distances.
