2005 BMW 1 Series

New technology cuts emissions by up to 21 per cent and improves fuel consumption by up to 24 per cent Tax-busting 60.1mpg 118d is BMW's most economical production car. The new BMW 1 Series goes on sale in spring 2007 and features a model line up that includes the most fuel efficient production vehicle BMW has ever produced. The introduction of a three-door model and a revised five-door come as a raft of new fuel-saving innovations are rolled out across the range.
Technologies such as Brake Energy Regeneration, Automatic Start-Stop function and Electric Power Steering are combined with lower rolling resistant tyres and a gearshift change indicator to encourage economical motoring. These innovations are in addition to the use of variable valve technologies and High-Precision Direct Injection engines on some 1 Series models that boost power output but cut fuel consumption and emissions.



Other engines in the new 1 Series range record economy improvements of up to 24 per cent compared to the previous model, while emissions have also been cut by up to 21 per cent. These improvements have not been to the detriment of driving pleasure. The new 1 Series is powered by a range of engines whose outputs have increased by up to 20hp with a consequential improvement in performance figures.

New fuel saving technology
Brake Energy Regeneration (iGR) makes its debut on the 1 Series. The system uses an Intelligent Alternator Control (IAC) and an Absorbent Glass Mat battery to recycle previously lost energy, in turn saving fuel. (concept carz) This is achieved as the IAC reduces drag on the engine by only engaging when required to charge the battery, whereas a traditional alternator is always pulling power from the engine. Additionally, the energy generated by the engine on over-run (under braking or descending a hill) was previously wasted. Now this lost energy is utilised by the IAC to charge the battery. iGR alone is responsible for a three per cent improvement in fuel economy.



The use of Electric Power Steering results in a 90 per cent energy saving compared to a conventional mechanical hydraulic steering system. Power assistance is now provided by an electric motor that works only when required, such as turning a corner. Other fuel saving enhancements have been made courtesy of various ancillary devices, such as the air-conditioning power supply being disconnected from the drivetrain when not in use. Even flaps behind the kidney grille improve economy, closing up for improved aerodynamic efficiency should the engine require less airflow. The feature also improves cold starting times.

Low running costs
The plethora of new technology showcased in the BMW 1 Series will have a significant impact on cost of ownership for customers. For the company car driver all but two engine variants now sit in the Band C category for Vehicle Excise Duty. This results in a saving of up to £505 for someone paying 40 per cent tax and up to £278 for those in the 22 per cent tax bracket. For all owners fuel consumption improvement means a 12,000 miles-a-year driver will save approximately £250 off the fuel bill.

Traction and safety
All BMW 1 Series models come with Dynamic Stability Control with Dynamic Traction Control for the best combination driving pleasure and safety. DSC allows drivers to make the most of the 1 Series' 50:50 weight distribution and rear-wheel drive configuration for the best on-road performance. The BMW 130i comes with five additional functions with its DSC+ system for enhanced convenience and driver safety: Hill Start Assistant, Brake Pre-tensioning, Brake Drying, Brake Fade Compensation and Soft Stop.

All BMW 1 Series have six airbags as standard, the Brake Force Display function on the rear lights to highlight sharp braking and Run-flat tyres with Tyre Puncture Warning System.

A new style of BMW 1 Series
To herald the introduction of the latest generation of engines, BMW's designers have refreshed the interior and exterior styling of the five-door model. The 1 Series now features a larger kidney grille for improved airflow to the engine. The lower front spoiler has also been reprofiled to create a larger air intake, while the spoiler protrudes further for a more pronounced, sporting look. The headlamp cluster remains the same size but a darker cover gives a subtle, more distinguished front end.

At the rear a restyled bumper gives the impression of a wider, lower car. The rear lamp cluster now features a new arrangement of lights, but retains its original shape.

The new three-door 1 Series features the same styling cues but its side view is naturally different. The passenger doors are longer than those on the five-door model and are also frameless in the style of a coupé. Inside, customers will also be able to choose between either a four-seat or a five-seat configuration. In the four-seat arrangement rear passengers are separated by a central storage compartment and sit in more sculptured seats. As a no-cost option the five-seat layout offers the traditional bench seat standard on the five-door 1 Series. The introduction of higher quality materials and minor changes to the layout of the interior enhance customer comfort and practicality.

Optional highlights
The new 1 Series comes with MP3 and ÚSB stick capability for the best in in-car entertainment. Customers with their favourite music loaded on an Apple iPod or a ÚSB stick can now plug these into the car to continue their listening. Tracks are selected via steering wheel controls or the iDrive system.

The optional Adaptive Headlights that turn to follow the intended course of the car have been improved on the 1 Series. Cornering light function is added to the package as standard. This means two additional lights turn at speeds of between 22 and 40mph to further illuminate the direction of travel on a twisting road.

Following February's announcement of the much-anticipated six-cylinder BMW 130i, BMW ÚK has confirmed the September 2005 introduction of the most potent 1 Series to date – the new 265 bhp BMW 130i.
Taking BMW's lightweight magnesium-alloy six-cylinder 258 bhp petrol engine as a basis, BMW engineers have wrung every last drop of power from the revolutionary powerplant, making the BMW 130i six-cylinder the most powerful engine in its class and the most powerful six-cylinder engine under a BMW bonnet, bar the M3. It is also the only car in its segment to offer a front-engine, rear-wheel drive layout – the optimum set-up for on-road dynamics.



The improvements in engine output enable the car to deliver a class-leading zero to 62 mph time of 6.1 seconds while top speed remains limited to 155 mph. Consumption is still frugal with the 130i recording 30.7 mpg on the combined cycle, while the EÚ4 compliant power train produces just 221 g/km.

The exciting performance figures of the BMW 130i are due in part to the VANOS and VALVETRONIC valve opening and valve lift control mechanisms on the 2,996 cc engine that ensure optimum combustion and engine breathing at all times. An electrically driven water pump also cuts down on internal engine friction and improves efficiency. Power is transmitted to the road via a standard six-speed manual gearbox.



M Sport Models

Complementing the class-leading performance of the BMW 130i is the announcement of a new range of M Sport models across the 1 Series range and on other BMW variants.

At the front, M Sport models have a lower front spoiler styled for increased aerodynamic efficiency while at the side, sculpted sills change the profile of the car. At the rear, a venturi cut-out in the rear bumper further accentuates the sporting theme. Bespoke 17- or 18-inch double-spoke alloy wheels, M Sports suspension and high-gloss Shadow Line finish the exterior package.

Standard interior trim for M Sport models includes Sports seats in an exclusive cloth / leather combination, M leather steering wheel, M doorsill finishes and an Individual anthracite headlining.

Similar M Sport interior and exterior enhancements will be available from September 2005 on 3 and 5 Series and X3 models and the new styling is expected to be offered on more models in the future.

The BMW 130i M Sport is currently (December 2005) not available in the ÚS.
