engine featured a 7 Cheap NFL Jerseys China ,000 rpm redline, Double-VANOS, which varies the intake and exhaust valves timings for both cylinder banks, and individual throttle butterflies for each of the cylinders, allowing for a much faster engine response time, which was offset by the slower electronic throttles. Overall the engine was much more powerful than previous incarnations, but had a notably slower throttle response than the non-electronic throttled predecessors.
All E39 M5s were equipped with a Getrag Type D six-speed manual transmission which provided the following gearing ratios:
? 1st gear: 4.23
? 2nd gear: 2.53
? 3rd gear: 1.67
? 4th gear: 1.23
? 5th gear: 1.00
? 6th gear: 0.83
It is the same transmission used in the E39 540i, but some changes were made to cope with the extra power the S62 engine produced A reinforced clutch, rear differential utilizing a shorter 3.15:1 ratio, and a limited slip differential with 25% maximum locking.
The E39 M5 suspension shared its basic aluminum-intensive Macpherson strutmulti-link design of the V8 engine E39 5 series. However, several changes were made by BMW M. Reduced spring height, 23 mm (0.9 in) lower. A specific shock valving, thicker front and rear anti-roll bars, polyurethane auxiliary springs Cheap Jerseys China , and steel ball joints.
Like all V8-powered E39 models, the E39 M5 was equipped with a recalculating ball steering system. Overall steering ratio was reduced to 14.7 from 17.9. It featured a Servotronic vehicle-speed-sensitive power assist which provides two levels of resistance controlled via console mounted Sport button. The Sport button also adjusted the electronic throttle butterflies for faster throttle response. The E39 M5 is equipped with four-wheel vented disc brakes measuring 345 mm (13.58 in) in diameter in front and 328 mm (12.91 in) in diameter in the rear. [3] On European-specification models, the rotors are of a “floating” two-piece design for reduced risk of cone distortion. Their lower unstrung weight improves ride quality and traction on bumpy surfaces as well. Anti-lock brakes were standard.
During its five years in production, there were some cosmetic changes in 2001 to include: [4]
? Revised headlight design incorporating illuminated “Corona Rings” (incandescent plastic rings surrounding the headlights)
? Jewel tone Celis tail light design
? Park Distance Control sensors in the front bumper (previously in rear only)
? Thicker three-spoke M steering wheel identical to the one fitted to the E46 M3
? Grey instrument panel
? Improved solar sensor for standard automatic climate control
? Revised navigationaudio unit with larger (6.5-inch) monitor (Standard on US Spec 2001-2003)
? Rear head protection airbags added
? Second-generation M Mobility tyre repair system in place of earlier version
? Available M Audio System with special tweeters, Kevlarcarbon coaxial speakers and two subwoofers behind the rear console
? Alcantara headliner included with Extended Leather interior (previously only included with Complete Leather)
For the subsequent two model years, changes were limited to the addition of new exterior colors (from 901 production) and the upgrade to a DVD-based navigation system (from 902 production).
The official BMW of North America statement (mentioned in the 2003 brochure) for the acceleration time from 0-60 mph is 4.8s. Official statements from BMW are typically conservative and many reviewers claim to have achieved this less than 4.5 seconds. It is electronically limited to a top speed of 250 kmh (155 mph), [5] making it the fastest 4-door saloon in the world at the time it was manufactured.
E39 M5 Touring
Although an E39 M5 Touring was considered, and at least one prototype was constructed (in Titanium Silver with a Black Exclusive leather interior), BMW M decided not to produce an E39 M5 Touring due to financial considerations. In February 2010, as part of BMW’s 25th Anniversary of the M5, they revealed this prototype M5 touring along with an E34 M5 Cabriolet, which also was never produced.
Flexible electronics design
Since the start of production the entire in-car entertainment system (Radio Function, Navigation System, and Television and Telecommunications systems) is based on a very flexible automotive computer system. [6] As a result the E39 models can all be easily upgraded with the newest BMW technologies including BMW’s Bluetooth System Cheap NFL Jerseys , the DVD based Navigation system, as well as BMW’s CD changers that play MP3s[7]
E60 M5 (2005-2010)
The E60 M5 was introduced in 2005. It has a 4,999 cc (305.1 cu in) BMW V10 S85 engine redlining at 8250 rpm, and developing a peak output of 507 PS (373 kW; 500 bhp) and 520 N?m (380 lb?ft) of torque. Unlike some other BMW engines which utilize Valvetronic to infinitely vary valve lift to eliminate the throttle plate; this engine has individual throttle bodies per cylinder. The E60 M5 was the world’s first production sedan to feature a V10 petrol engine. A turbo-diesel V10 had been available in the Volkswagen Phaeton in Europe since 2002. [9]
Other key features include a stiffened aluminum chassis and a 7-speed SMG III sequential manual gearbox, also known as a single-clutch automated manual transmission. Front fog lights are unavailable for the M5, as the amount of air required to cool the brakes under spirited driving applications requires the spaces under the bumper, normally occupied by fog lights in other E60 cars, to be reallocated for air cooling ducts.
Despite the criticism of the Chris Bangle-designed chassis, the difficult iDrive interface, and the lack of smoothness of the SMG III transmission, the E60 M5 was the most successful M5, despite being on the market for one year shorter than the E39 M5.
