2006 BMW Z4

The BMW Z4 certainly means business: This is exactly what a BMW roadster must look like, this is exactly how it must drive. The Z4 is a breathtaking experience on the road appealing to all your senses as a purist automobile for the connoisseur. It not only represents one side of BMW's new design language, but also sets new roadster standards in many areas: Self-confident, powerful, sporting and aesthetic, the Z4 offers extremely precise and safe handling ensuring driving pleasure of the most supreme calibre beyond comparison in the market.

BMW's new two-seater is making its debut as the Z4 3.0i with a 170 kW/231 bhp powerful straight-six and six-speed manual gearbox and as the Z4 2.5i featuring a 141 kW/192 bhp straight-six combined with a five-speed manual gearbox.

Through its proportions alone, the Z4 is a truly remarkable car: The long, sleek and stretched-out engine compartment, the snug cockpit wrapped around the driver and passenger, and the short, muscular rear end – there is hardly any other roadster these days with comparable dimensions. Wheelbase measuring 2,495 millimetres or 98.2 inches and overall width of 1,781 millimetres or 70.1 inches set a new standard in this class, while the overall length of 4,091 millimetres or 161.1 inches is both sporting and compact. The result is a genuine athlete resting firmly on the road with short overhangs front and rear and without one single gram of fat.

2006 BMW Z4The Z4 has two waistlines. The lower waistline extends from the engine compartment lid across the door, first moving down and then up again towards the rear. This creates an impression of powerful self-confidence and at the same time is reminiscent of the classic, door-less roadster of the past, giving this two-seater its unmistakable character. The upper waistline, by contrast, extends in a powerful arch from the beginning of the compartment lid all the way to the rear. And the door line extending upwards to the rear at a slight angle is equally exciting and fascinating in its look.

The Z4 2.5i is candy to the senses. With the first glance comes instant gratification, quickly followed by more profound pleasures and lasting rewards. A 2.5-liter six-cylinder engine that can clock 60 mph in 7.1 seconds* on its way to a top speed of 146 mph. Massive four-wheel disc brakes for quick stops. Laser-sharp steering for quick lane changes and tight cornering. The Z4. Only thing missing is an applause meter.

2006 BMW Z4
BMW ÚK has announced details of the latest M car – the new BMW Z4 M Roadster. Three-years after the Z4's launch as the most performance-focussed roadster on the market, BMW M have turned their attentions to the Z4, creating BMW's fastest accelerating open-top. With 343hp equating to 106hp per litre, zero to 62 mph acceleration of 5.0 seconds and an electronically limited top speed of 155mph, the new M Roadster is set to re-write the rulebook for performance, agility and dynamism.

The Detroit Auto Show in January 2006 will also see the launch of model updates for the entire BMW Z4 Roadster range. The new Z4 will feature a new engine line-up, new gearbox options, styling enhancements and still the fastest opening fully automatic convertible roof in the world.

The new BMW Z4 M Roadster:Like the current BMW M3 Coupé and Convertible, the new BMW Z4 M Roadster features the five-time International Engine of the Year. The reigning three to four-litre champion delivers 343hp at 7,900rpm and 365 Nm of torque at 4,900rpm from its 3,246cc six-cylinder Motorsport engine. The powerplant is mated to a six-speed manual gearbox and BMW M's variable M differential. The result is excellent stability and traction, especially when accelerating out of bends.

Únlike the ‘standard' Z4 that uses an electromechanical steering system, the new Z4 M Roadster uses a hydraulic power assistance system. The ‘standard' car also uses Run-flat tyres as opposed to the M Roadster's non-Run-Flat items – both features that M, as a separate division, believes give the car its own ‘M' character. These features are reinforced by BMW M's floating compound high-performance braking system, originally conceived for the BMW M3 CSL, resulting in a 62mph to zero stopping distance of just 34 metres.

Visually, the new Z4 M Roadster is differentiated from the ‘standard' car by numerous details inside and out. From the front, the lower valance, large air intakes and dual styling lines on the bonnet clearly identify the M car while, at the rear, BMW M's trademark quad-tailpipes and aerodynamic diffuser highlight the car's potential. The M-styling is finished off with exclusive M double-spoke 18-inch alloy wheels with 225/45ZR18 tyres on the front and 255/40ZR18s on the rear.

The Z4 M Roadster is available in eight exterior colours, with three exclusive M colours – Sepang Bronze, Interlagos Blue and Imola Red.

Internally, the familiar Z4 interior is complemented by new leather finishes in Black, Imola Red, Light Sepang Bronze or Sepang Brown and trim strips in Hexagon Aluminium, Black Carbon Leather or Madeira Walnut wood. In front of the driver a bespoke BMW M instrument binnacle featuring a black background with white numerals and red needles helps keep the driver in touch with vital driving information.

2006 BMW Z4
Coinciding with the launch of the BMW Z4 M Roadster, the entire Z4 Roadster range receives visual and substantial mechanical enhancements.
Engines:
Topping the new range is the Z4 3.0si, featuring BMW's innovative magnesium alloy in-line six-cylinder engine. Featuring Valvetronic valve lift and VANOS valve timing, the Z4 3.0si develops 265hp at 6,600rpm and 315Nm of torque at 2,750rpm. These impressive statistics help power the car from zero to 62mph in 5.7 seconds and, if left unchecked, continues to a maximum electronically limited top speed of 155mph. However, these levels of performance aren't at the expense of economy, with the 3.0si delivering 32.8mpg over the combined cycle.

Two in-line six-cylinder 2.5-litre variants will be offered – the Z4 2.5si and 2.5i. Based on the same engine, but differentiated by output, the 2.5si offers 218hp and 250Nm of torque from its 2,497cc powerplant. This gives the power to sprint from standstill to 62mph in 6.5 seconds and on to a top speed of 149mph, while still delivering 33.6mpg on the combined cycle. By contrast, the 2.5i delivers 177hp and 230Nm of torque.

The only engine carried over from the out-going range is the four-cylinder Z4 2.0i that was launched in April 2005. Produced at BMW's Hams Hall plant near Coventry, the 1,995cc engine features BMW's Valvetronic and VANOS technologies to develop 150hp at 6,200rpm and 200Nm of torque at 3,600rpm. The lighter weight of this engine helps deliver sharp performance, with the Z4 2.0i dispatching the zero to 62mph sprint in 8.2 seconds before hitting a top speed of 137mph.
