Recent Changes

In 2006, BMW updated the Z4 line by introducing the M Roadster, and later the M Coupe, with the vaunted S54 "M" engine. The standard cars received the new N52 I6 engines. The N52 features a magnesium block construction, which consists of an aluminium interior for the cylinders, and an outer magnesium block. The engine features BMW's Valvetronic variable valve timing system for increased performance, are considerably more powerful through the middle of the rev range, and also improve fuel economy noticeably. A final benefit of the N52 engines is that they improve handling and turn-in due to the decreased weight over the nose of the car. This is particularly noticeable when compared to the Z4 M, which continued with the heavier S54 iron block engine.

Standard equipment include Run Flat Tyres, ABS Brakes, Stability Control, Traction Control, CD Player, Power Locks, Power Windows and Air Conditioning. The Z4 included Side Airbags, Driver Airbags, Passenger AirBags, Knee Airbags and 5 Star Rollover Protection.

In addition to the powertrain updates, BMW made mild revisions to the styling of the Z4, added several electronic features, and increased the brake size on the 3.0si models.

The 2006 BMW Z4 received a number of updates including a revised exterior, more powerful engines and improved interior features. Highlighted by a new front bumper ensemble with a larger air intake, rectangular foglights and front side reflectors, the exterior also received new wheels, rear bumper and taillight designs. The interior was fitted with a new aluminium trim, shift knob for automatic transmission and new colors. The 3.0i replaced the 2.5i and the 3.0si replaced the 3.0i. Power was increased to 215 and 185 lb-ft of torque for the 3.0i while the 3.0si got 255 horsepower and 220 lb-ft of torque. A 6-speed manual transmission was standard with an optional 6-speed automatic. Standard 17-inch wheels were standard on both trims and the Sport Package also features new wheels as well.

The Z4 M shares the same engine as the E46 BMW M3, but due to gearing differences, is marginally slower than the M3. North American version is 3 horsepower shy of the M3's 333 horsepower. However this is better than the Z3 version, which while using the same engine was all the way down to 315 horsepower. 0-60 mp/h takes 5.0 seconds, and the top speed is limited to 250 km/h (160 mph).

Unique Attributes

BMW Z4 2.2i launched in 2004 that cost £18,500 in UK and its speed can reach 100 km/h (62 mph) in 7.7s. BMW claimed a 6.8s time to 100 km/h (62 mph) with a manual transmission. It weighs 1,335 kg (2,940 lb) with a manual transmission — 30 kg (66 lb) lighter than the 3.0L version, but still heavier than the 2.5L Z3's weight of 1,315 kg (2,900 lb). The 3.0i has a claimed 0- 100 km/h (62 mph) acceleration of 5.9s.

A Sport Package", adding stiffer and lower suspension, larger wheels with run-flat tyres.

Dynamic Driving Control, BMW's Vehicle Stability Control system, was also available.

The Z4's design addressed many criticisms of the preceding Z3; the Z4 is larger, and has a significantly stiffer chassis. The Z4 features a strut type front suspension like its predecessor. The rear suspension, however is considerably different from that of the Z3, which was based on that of the E30 BMW 3 Series. Instead of a semi-trailing arm suspension, the Z4 uses a more advanced multi-link suspension.

Interior

Criticisms

  • Electro-mechanical power assist steering. The Z4 includes an electro-mechanical power assist steering system which earned the vehicle considerable criticism. The system was introduced as a fuel-saving device by removing hydraulic pump loads from the engine. BMW claims this system provides a "more dynamic drive" and a "more direct feel." Motor journalists and racing drivers complained, however, that this device gave the vehicle an artificial, synthetic or indirect steering feel. The BMW Z4 M on the other hand, only included conventional hydraulic assistance, said to have given the car a much more direct and communicative feel.
  • BBC Top Gear's journalist Jeremy Clarkson has on a couple of occasions complained on the harsh ride of a car he otherwise rather favours. He attributes this to be a feature designed to please American drivers, who, accustomed to local soft suspensions and badly engineered vehicles, believe any harsh and overly firm ride is equivalent to good suspension dynamics.

Variations

Z4 Coupé (E86)

BMW unveiled a concept coupé version of the Z4 at the Frankfurt Motor Show in 2005. The design of the Z4 and Z4 coupé has variously been ascribed to Anders Warming, Chris Bangle, the highly questioned former BMW Head Designer, and Adrian von Hoydonk, the present one.<ref>Template:Citation/core{{#if:|}}</ref><ref>Template:Citation/core{{#if:|}}</ref> The company announced in 2005 that the coupé would be available for production including the return of the M Coupé. The production cars were introduced at the New York Auto Show in April 2006.

The M Coupé shares its 3.2 L Inline-6 with the M Roadster. Thanks to its hatch design, the Z4 Coupé offers 10.1 cu-ft of trunk space,<ref>Template:Citation/core{{#if:|}}</ref> as opposed to 8.5 cu-ft for the roadster.<ref name="2008roadster">Template:Citation/core{{#if:|}}</ref>

The E86 Coupé features:

  • a fixed hard-top roof which yields additional torsional rigidity—32,000 N·m (24,000 lb·ft) per degree of body twist—which improves driving dynamics and corner handling.
  • a 'double bubble' contoured roof which serves as an aerodynamic aid, and offers more headroom than the roadster (when closed);
  • a sleek fastback rear window;
  • an integrated spoiler shaped to deliver downforce to the rear axle at speed.


Motorsports

Dieter Quester, Dirk Werner, Jamie Campell-Walter and Tim Mullen won the Silverstone Britcar 24 Hour Race with a BMW Z4 M Coupé.<ref>Template:Citation/core{{#if:|}}</ref> The unit of the racing version is modified and reinforced version of the S54B32 3.2-litre engine, delivering around 294 kW/400 hp. The car is made by BMW's M Division and called the Z4 M Coupé Motorsport.<ref>Template:Citation/core{{#if:|}}</ref> The Z4 Coupe Motorsport version weighs 1,200 kg/2,643 lb with a driver and has a 120 litre/30 gallon fuel tank for endurance racing. The racing kit for the Z4 M Coupé is available for € 250,000, plus VAT (391, 025 U.S. dollars) in addition to the list price of the car. The Racing Kit is very popular among N Class drivers, which also got a lot of good results in the track.

In August, 2008, a modified Z4 debuted in Round 6 of the Super GT season, participating in the GT300 class. It is powered by a detuned version of the S62 V8 engine from the E39-Series M5. Although it is well known by fans since it has a unique image (or called "Itasha"), this car also marked the return of BMW to Super GT series since their exit from the previous JGTC (which they used the M3). They continues to participate in the 2009 Super GT season other than Sepang Race<ref>Template:Citation/core{{#if:|}}</ref>, and they would replace their H-pattern to a sequential transmittion, as well as their S62 Engine with an S65B40 after race 3, after they had suffered an unrepairable engine blow in race 2 at Suzuka.<ref>Template:Citation/core{{#if:|}}</ref>

In 2008 Super Taikyu Endurance Series (equivalent to Group N championship) in Japan, both BMW Z4M entered by Petronas Syntium Team won the Super Taikyu 1 class first and second taking both the championship and drivers title. Both cars dominated the series by taking first and second at every race in the 2008 season beating cars like Porsche GT3 (both 996 and 997), Honda NSX, Mitsubishi Evolution X, Mazda RX-7, Nissan GT-R and Nissan 350Z. Super Taikyu endurance races usually last for at least 500 kilometers or 4 hours highlighted by the race of the season, 24 Hours of Tokachi. In total Petronas Syntium Team gather 277 points compared to the second place team Endless Sports with a mere 98 points.<ref>Template:Citation/core{{#if:|}}</ref> The cars were driven by established and popular drivers such as Nobuteru Taniguchi, Masataka Yanagida, Manabu Orido and father and son pairing of Hans-Joachim Stuck and Johannes Stuck.<ref>Template:Citation/core{{#if:|}}</ref>
