E90/E91 xDrive

Introduction

The new 3 Series Sports Wagon satisfies the standards of style, flexibility and perfor¬
mance - far in excess of sheer driving pleasure. It combines first class driving dynamics
with versatile functionality.

It will be introduced in the US as a 325xiT in September 2005. Variants will be available
in March 2006.

The technical basis of the E91 is the E90, the 3 Series Sedan, with which the Sports
wagon is virtually identical up to the B-pillar.Therefore, what has already been said about
the 3 Series Sedan also applies to the Sports Wagon: It is - when compared with the
previous model (E46) - stronger and bigger, and the E91 has above all become more
functional.

Like the Sedan, the E91 has sporty proportions thanks to its long engine bonnet and a
striking swage line rising along the entire side of the caras an expression of powerful
dynamics.

The roof line of the Sports Wagon is like a Coupe and the roof spoiler is integrated in
these lines. Roof rails are standard.

Engines

Initially the E91 Sports Wagon will only be offered as a 325xiT with later configurations
to follow.

The new BMW N52-generation inline six cylinder engines deliver incomparable agility
with more power but less weight and lowerfuel consumption. VALVETRONIC and dou¬
ble VANOS are additional features of this engine which, in the E91 as already in the E90,
is combined exclusively with 6-speed gearboxes.

xDrive All-Wheel-Drive System

Initially the E91 Sports Wagon will only be offered in an all wheel drive version. At the
same time, the all-wheel-drive system will also be making its debut in the new 3 Series
Sedan (September2005).

The system and function are already familiar from the X3, X5 and 5 Series. Some com¬
ponents such as e.g. the propeller shafts have been geometrically adapted to the altered
space conditions in the 3 Series.
