The BMW 3 Series E90 was revealed at the Geneva Motor Show in March 2005. For more than 30 years now, the 3 Series BMW was considered the definitive driver's car. The E90 comes with impressive, innovative improvements for engine, chassis, safety technology as well as driving comfort. The 3 Series is by far the most important model in the BMW range, gathering the most sales. As a result, the vehicle is more conservatively styled than other BMW's and isn't quite as radical as the Z4 or the 5 Series. The front end has a very dynamic look, particularly the headlights, while at the rear things still generate controversy with the brake lights moving away from BMW convention and adopting an almost diamond-shaped design.

The E90 sedan is 49 mm longer, 78 mm wider and 9 mm taller than its predecessor. The wheelbase is longer by 35 mm. Large amounts of aluminum were used in the body work and suspension in an attempt to keep the weight close to previous models. To minimize weight, which is the killer of s ports car performance and handling, BMW has employed magnesium for the first time in large-scale series production, achieving a substantial 30 percent weight saving compared with an all aluminum alloy engine. Magnesium is used for the crankcase, the crankshaft bearings, and on the cylinder head cover.

Reflecting its heritage, the new BMW 3 Series has classic BMW characteristics; a longitudinally-mounted engine, rear-wheel drive, and perfect axle load distribution of 50:50, combining to deliver superior all-round dynamic agility.

A unique feature available for the first time in the compact sports luxury segment is BMW's active steering, beeing offered as an option on 6-cylinder models. Active steering provides a more direct transmission ratio at low speeds and an indirect ratio at higher speeds, thus solving the conflict of interest between agility, stability, and comfort, which conventional steering simply cannot offer. BMW active steering is enhanced for the new 3 Series by an additional feature particularly important in everyday motoring in poor conditions. When the driver applies the brakes on surfaces with varying frictional coefficients such as icy patches, snow and asphalt, active steering - actively intervening in the steering control - stabilizes the car more quickly and more precisely than a regular motorist would ever be able to do.

Other features that are available on the E90 include DSC, or Dynamic Stability Control. It appears in its latest version to provide safety of the highest standard and on the 6-cylinder models DSC is enhanced with useful functions such as dry-braking of the brake discs on wet roads, Brake Standby with the brakes being alerted by pre-aligning the brake linings, a Start-Off Assistant preventing the car from rolling back when setting off on a gradient (for hill starts), as well as anti-dive control when applying the brakes slowly.

BMW also spent plenty of time and money insuring that the interior is "modern and harmonious". As with all BMW cars, the cockpit is clearly structured and driver-oriented and the driver zone conveys important information with optimum clarity.

The centre console serves as the comfort zone within perfect reach of the driver and front passenger and superior ergonomics means controlling important features such as the air conditioning and radio is easy, convenient and safe.

Complex systems with high information density are controlled via iDrive, which is an optional on E90, but having a simplified menu than his bigger brother, the 7 Series. For those who do want iDrive, the system can be further optioned with what BMW called Comfort Access, an intriguing idea that renders the conventional ignition key obsolete. A transmitter referred to as the ID Sensor enables the owner to enter the car and start the engine without even touching the key. And in conjunction with Key Memory, the ID Sensor recalls the seat position, mirrors, automatic air conditioning and radio tuning settings used on the driver’s last journey.

The E90 also introduced run-flat tyres to the 3 Series range. This feature enables the car to continue for up to 250km after a puncture at a speed of up to 80km/h without destroying the tyre or the rim. Consequently, cars with run-flats are not equipped with a spare tyre.

3 Series E90 320Si model

With Andy Priaulx from Team BMW UK claiming the FIA World Touring Car Championship, BMW has announced a limited-edition version of BMW’s 2006 World Touring Car – the BMW 320si Saloon.

Designed to comply with FIA homologation regulations, only 2,600 cars will be sold worldwide. All feature a hand-built four-cylinder engine made at BMW’s engine plant at Hams Hall, near Coventry. The high revving 2.0-litre unit delivers 173hp at 7,000rpm (before reaching its red line at 7,300rpm) and 200Nm of torque at 4,250rpm.

This engine powers the BMW from zero to 62mph in 8.1 seconds and, if left unchecked, onto a top speed of 140mph. Although inspired by the racetrack, the car still delivers 31.7mpg on the combined cycle and conforms to the EU4 emissions regulations.

This high level of performance has been achieved using BMW’s motorsport technology. Compared with the ‘standard’ BMW 320i, the engine has been significantly modified with larger induction and exhaust valves to increase airflow. The cylinder bore has increased by 1mm to 85mm while the stroke has been reduced by 2mm to 88mm.

The compression ratio of the engine has also been increased from 10.5:1 to 11.0:1, helping to boost power by 23hp over the 320i. Additionally, instead of running with grey-cast-iron cylinder liners, the pistons run in special aluminum-alloy liners in the cylinder block. Engineers have also decided to remove BMW’s patented VALVETRONIC induction system, reverting to a conventional throttle due to the higher engine speeds demanded by a racing engine.

In a direct link with BMW’s motorsport programmes, the cylinder head is cast at BMW’s Landshut foundry alongside Formula One engine blocks. Additionally, to save approximately 10kgs of weight and lower the car’s centre of gravity, the cylinder head cover is made of carbon fiber.

The new BMW 320si mates its high levels of performance with World Touring Car looks. The specification of the 320si is based on the 3 Series M Sport model that includes front and rear aerodynamic body styling, sports seats, sports suspension and aluminum interior trim. Additionally, the BMW 320si features Touring Car-style alloy wheels with BMW Motorsport motif. The front wheels are 8J x 18 fitted with 225/40 R18 tyres while at the rear the 8.5J x 18 wheels are fitted with 255/35 R18 tyres. Finally, mirror caps finished in satin chrome differentiate the car from a standard 3 Series.
