The BMW Z4 is a rear-wheel drive sports car by the German automaker BMW, known as the E85 in roadster form and E86 in coupe form. Production started in 2002, and thus replaced the BMW Z3. The design addresses many criticisms of the Z3; the Z4 is larger, and has a significantly stiffer chassis. It is built in Spartanburg, South Carolina. Initially, the Z4 was available only as a roadster, but in 2006 a coupe version was officially launched.

The Z4 was designed by Chris Bangle and began the controversy over his "flame surfacing" design and aggressive styling choices, which can also be seen on most modern BMW cars, most noticeably the 7 Series and 5 Series. As of 2007, the entire BMW car line, including the BMW 3 Series and X5 SAV, had incorporated Chris Bangle's design theme.

The Z4 features a strut type front suspension like its predecessor, the Z3. 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.

It is due to be complemented by a new model, the Z2, in 2009.


The Z4 offered a choice of four straight-six engines: 2.2 L, 2.5 L, 3.0 L, and 3.2 L. All are variants of the BMW M54 engine. In the European market, a 2.0 L straight-4 is also offered. The 2.2 L, 120 kW (170 bhp) version can reach 100 km/h in 7.7 s, but is not sold in the United States.

The 2.5 L engine produces 141 kW (192 bhp) at 6000 rpm. BMW claims a 6.8 s time to 100 km/h (62 mph) with a manual transmission. It weighs 1,335 kg (2,932 lb) with a manual transmission—30 kg (66 lb) lighter than the 3.0 L version, but still heavier than the 2.5 L Z3's weight of 1315 kg (2899 lb).

The 3.0 L, 170 kW (215 bhp) (at 5900 rpm) straight six has a claimed time to 100 km/h (62 mph) of 5.9 s.

The 3.2 L motor produces 246 kW (330 bhp) at 7900 rpm and (262 ft·lbf) of torque at (4900 rpm)[1]

The most powerful car of the Z4 line-up is the Z4 M. It features a naturally aspirated, in-line six cylinder engine, used in the third generation of the BMW M3. It produces 340 bhp at 7900 rpm, and 365 nm (270 lb-ft) of torque. 0-100 km/h takes 5 seconds, and the top speed is limited to 250 km/h.

2003 BMW Z4 roadster

Five-speed manual gearboxes are standard on all models except the 3.0 L and the M Roadster, which has a 6-speed Getrag. 5-speed or 6-speed automatic are available on all non M cars. The M Roadster shares its 6-speed Getrag 217 manual gearbox with the M3. [2]

A Sport package is also available, which adds stiffer and lower suspension, larger wheels with run-flat tires, and Dynamic Driving control, BMW's Vehicle Stability Control system.

2006-2007 Z4 3.0si

In 2006, BMW updated the Z4 line by installing its new N52 I-6 engines. In the 3.0si, this engine makes 190 kW (255 bhp) and 220 lb·ft (298 N·m) of torque. The N52 features a magnesium block construction, which consists of an aluminum interior for the cylinders, and an outer magnesium block. This produces an engine block that weighs only 50+ pounds. 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 continues with the heavier S54 iron block engine.

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.

Bostian Bridge circa 1857

Bostian Bridge circa 1857

The passengers were grumpy and heavy-eyed as they boarded the train in Salisbury during the early morning of August 27, 1891. The train was headed to Asheville, and the riders settled into their seats and tried to catch a few more minutes of sleep.

Around three a.m., the passengers were suddenly awakened by suddenly bucking and rocking of the train. The engineer fought for control as the passenger train raced across the stone-and-brick Bostian Bridge near Statesville, but the train suddenly derailed. The chug and whoosh of the rushing train was replaced by the scream of metal and the sounds of the huge train falling, falling down towards the creek bed sixty feet below the bridge. The horrible thunder of the train as it smashed into the stream was quickly replaced by the equally terrible sound of trapped passengers screaming and moaning in agony as the twisted wreckage of the train was encompassed by the waters of the creek. Twenty-two people were killed that night in the worst train wreck in the history of North Carolina.

Fifty years to the day after the wreck, a woman waiting by her stranded car near the Bostian Bridge in the early morning hours of August 27 saw a train come rushing down the track, its head light gleaming brightly in the darkness and the whistle blowing. As it raced across the bridge, it suddenly derailed, screaming its way down and down sixty feet to smash into the creek bed below. The woman was terrified. She ran toward the wrecked train and gazed down into the creek. She could hear the frantic cries and agonized moans of the survivors.

At that moment, a car pulled up beside her stranded vehicle and her husband jumped out, followed by the owner of a local store who had come to help them fix their flat tire. She ran towards them in a frenzy, desperate to get help down to the poor trapped passengers below. When they heard her story, the men ran to the edge and looked down into the creek bed. There was nothing there. The woman had seen the train wreck of Statesville re-enacted before her eyes.

Some people say the phantom train appears each year in the early morning hours of August 27th and is wrecked before the eyes of any who watch for it.
