The new BMW M3 Saloon

Hot on the heels of the arrival of a new M3 Coupé, BMW UK has announced details
of the four-door M3 Saloon. While four generations of M3 have been built, this
is only the second time an M3 Saloon has been offered. Thirteen years after
the launch of the original M3 Saloon, the new car offers the same levels of
scintillating performance as the latest Coupé. With the added practicality of
the four-door bodyshell, the new M3 Saloon will appeal to an even broader
audience.


Class-leading engine and drivetrain
Like the Coupé, the engine in the new M3 Saloon develops 420hp at 8,300rpm and
400Nm of torque at 3,900rpm. The 3,999cc V8-power unit red-lines at 8,400rpm
but to highlight the real-world driving flexibility of the engine, 85 per cent
of torque is available over an engine range of 6,500rpm. Power is transferred
to the road by BMW M's six-speed manual gearbox and variable M differential.
This conveys up to 100 per cent of available power to the wheel with most grip.

The M3 Saloon completes the sprint from zero to 62mph in 4.9 seconds, only 0.1
seconds slower than the Coupé, before going onto a limited top speed of
155mph. BMW's EfficientDynamics programme, however, ensures that these
supercar levels of performance do not compromise economy with the car
delivering 22.8mpg on the combined cycle.

BMW EfficientDynamics, even in M cars
In common with all new BMW models launched in 2007, the new M3 Saloon features
Brake Energy Regeneration. This technology uses an Intelligent Alternator
Control and Absorbent Glass Mat battery to recognise when the engine is on
over-run and activates the alternator to charge the battery with what would
previously have been wasted energy.

Another aspect of BMW's EfficientDynamics programme is lightweight technology.
Although not featuring the carbon-fibre roof panel from the Coupé, it does use
other lightweight, but high-strength, materials. Using a light-alloy engine
block manufactured alongside F1 engines at BMW's foundry at Landshut, Germany,
the new V8 powerplant weighs a mere 202kgs. To put this achievement into
context, this is 15kgs less than the six-cylinder engine in the
previous-generation M3.

To further highlight the weight advantages, the crankshaft in the new engine is
made from one complete forging and weighs only 20kgs. Additionally, the front
axle components are built entirely from aluminium. Even the five-link rear
axle, normally constructed from high-strength steel, has aluminium components
to save weight.

Personalised settings
Like the M3 Coupé, the Saloon variant also features an M Drive Manager that
brings together numerous personalised functions of the car. The optional
Electronic Damper Control (Normal, Comfort and Sport), three DSC+ traction
control settings and three specific engine control maps, plus the response rate
of the Servotronic power steering can be controlled with one button on the
steering wheel. Once the desired settings are created in the iDrive menu, part
of the standard Professional navigation system, one push of the MDrive button
transforms the M3 from a car suitable to collect the kids from school in into
supercar-beater.

Four doors but clearly an M car
BMW M's philosophy of redesigning the 'standard' car from the ground up is
showcased well in the new M3 Saloon. Although visually similar to the 3 Series
Saloon, almost all the bodyshell parts are different with the emphasis on the
sporting dynamics of the car. So much so that the M3 Saloon features the same,
sleek front end design from the Coupé. This includes the lowered, sportier
headlamp design and striking power dome in the bonnet. Primarily, the design
of the front of the car is created by the need for significant volumes of air
for the induction system. As a result, the M3 does without front fog lamps,
whilst three large air ducts in the front lower valance keep the engine
breathing.

Like the Coupé, the new M3 Saloon features 18-inch Dark Graphite double-spoke
light-alloy wheels as standard, with a forged and polished 19-inch wheel
available as an option. Another BMW M trait, the side gill in the front wing,
has been elongated for the Saloon, mirroring the design from the M5. Also
carried-over from the two-door are the aerodynamically-effective door mirrors.

From the rear, an aerodynamic diffuser emphasises BMW M's trademark twin double
exhaust pipes protruding from beneath the valance. The bootlid also features a
discreet lip spoiler.

Details about the launch date and pricing of the M3 Saloon will be announced in
the future.
