It is simply foolish for an auto manufacturing company to continue using the name of a particular vehicle model that had for itself a bad reputation. Should they plan to release an enhanced version of the same car, it would do them better if they give it a new name. This is just what BMW did when they replaced the problematic BMW Z3 with the BMW Z4. But mind you, the BMW Z4 is a whole lot different from the Z3. It is an entirely new car with an entirely new attitude.
The BMW Z4 is a 2-door rear wheel drive roadster introduced by BMW in 2003 to replace the ailing BMW Z3. Many would think of the roadster as just another generation for the BMW Z3. But with all the revisions made, including a larger size, stiffer chassis and more powerful engines, the BMW Z4 qualifies itself as a whole new vehicle, thus justifying the change in name.
What makes the BMW Z4 an entirely different car from the BMW Z3 are the various BMW Z4 parts it is equipped with and the brand new design that the roadster sports. The vehicle's style was definitely different, thanks to the "flame surfacing" design cues of BMW design chief Chris Bangle. And while the roadster's front suspension was essentially the same with the Z3, the multi-link rear suspension design was its own.
In various BMW dealerships today, the BMW Z4 is being offered in two trim levels. The BMW Z4 2.5i is equipped with a 2.5-liter 6-cylinder engine that runs with 184 hp and 175 lb-ft of torque. The upscale trim is the BMW Z4 3.0i, which comes equipped with a 3.0-liter 6-cylinder engine that registers an output of 225 hp and maximum torque of 214 lb-ft. Both engines are variants of the BMW M54 engine that is also used on many other BMW vehicles today.
An entirely new car with an entirely new attitude, the BMW Z4 is aimed to achieve what the BMW Z3 failed to.
Car Care Tips for Storing Your BMW Z4 for the Winter
The BMW Z4 roadster is a two-seat sports car that perfectly combines elegance with sportiness. Are you planning to put your four-wheel machine away for the winter? Keep your sports car in shape and make it ready for the road next spring by following these car care tips before you store it in the garage:
- Before anything else, do the car care tasks first.
To prevent the weatherstripping from sticking to the car doors when your Z4 stays in the garage for a long period, open the trunk, windows, and doors and then spray dry Teflon lube on all the weatherstripping. Apply fresh grease into all the grease fittings. Spray white lithium grease on to your door hinges and hood latch to keep corrosion at bay. Also, do not forget to change oil and filter to protect your engine from corrosion while your car is stored for the winter. Make the clean oil spread in the engine compartment by running the engine for a few minutes.
Use jack stands to raise your Z4 and then lower your tire pressure to 25 psi. Lowering the tire pressure prevents flat spots on your tires that normally happen after long-time storage. Flat spots on tires can lead to a shaky ride next time you take your car out for a spin.
- Fill your car with gas and put in fuel stabilizer.
A bottle of fuel stabilizer, which you can buy from a car parts store, is all you need to keep your fuel fresh for long periods and to keep your engine from getting damaged after storage by preventing accumulation of varnish and gum. The fuel stabilizer also helps ensure quick and easy starts after you take your Z4 out of your garage. With a fuel stabilizer, you will not need to drain all fuel from your car prior to storage. Once you get a hold of a fuel stabilizer, have the tank filled with gasoline and put the right amount of stabilizer. Have the fuel stabilizer combined with the gas and circulated throughout the fuel system by driving your vehicle for about 15 minutes.
- Keep your battery protected.
You have two options: you may take it out of your Z4 and store it indoors, or you connect it to a battery maintainer to keep it fully charged while your car is stored. If you will go for the latter, hook up the clamps of the battery maintainer to your battery and then plug in the maintainer and set the battery type and voltage. Push the start button and close the hood. If you do not perform any of these two options, your battery will lose its charge when it is stored. Eventually, it will freeze—and you know the horror story that will happen next.
- Cover your car with a breathable fabric.
Storing your car outdoors? A waterproof tarpaulin just won't do, as it traps moisture and causes rust. Instead, use a breathable water-resistant custom-fitted cover. Be sure that the tires are covered as well to protect them from ultraviolet rays.
Tracing the Origins of the Stylish and Power-packed BMW Z4
A German sports car with a rear-wheel drive, the BMW Z4 is a powerhouse-on-wheels that was introduced in 2002. Because of its distinct exterior, it earned the Design of the Year Award from Automobile Magazine in the same year. Several generations later, the Z4 continues to blaze the trail and raise the standards for sports cars.
The first-gen BMW Z4 is available in two versions: a roadster (E85) and a coupe (E86) and was designed by Danish designer Anders Warming. The engine line-up included several options. For the roadster, buyers can choose from a 3.0i, a 3.0si, 2.5si, a 2.2i, or a 2.0i engine. As for the coupe, consumers only have one option: a 3L 255 hp I6.
In 2004, upgrades included 16-inch wheels for the 2.5i model, 17-inch wheels for the 3.0i, leather interiors for the 2.5i and 3.0i, Xenon headlights, and a console button for the Dynamic Driving Control system. Optional features are a Sport Package, a wind deflector, and a removable hardtop. More optional features in the following year were offered. These include a concierge service and the BMW Assist emergency, navigation system, and heated seats. The Sequential Manual Gearbox was carried over to the 3.0i, although it was removed from the 2.5i version.
In 2006, a hatchback coupe was introduced, while the E85 received more upgrades such as a new style and more power-packed engines. In the same year, the Z4 M Roadster was also launched. More known as the M Roadster, it uses a 3.2 L, S54-inline engine.
The E89 or second-generation BMW Z4 was introduced at the 2009 North American International Auto Show. This model features a seven-speed, double-clutch gearbox and an expanded transmission line-up for the 28i and 30i versions. Other standard technologies used by the second-gen Z4 are the EfficientDynamics braking system, the Drive Dynamic Control, and an electro-mechanical hand brake. It’s also equipped with the following standard components: a belt load limiter and pretensioner, emergency brake assist, four airbags, a reinforced windscreen, and two roll bars behind the seats.
The current Z4 is a retractable hardtop, with the design a concept of designers Juliane Blasi and Nadya Arnaout. The hardtop features a lightweight shell made of aluminum and an electro-hydraulic mechanism. It also automatically folds in just 20 seconds.
In 2013, upgrades include modified back lights and new LED headlights. A new engine is offered for the Z4 sDrive18i version, and two trim packages were added: Design Pure Traction and Design Pure Balance. Since 2013, a new color—Valencia Orange Metallic—has been included in the roster of choices. Modified Z4s such as the BMW Z4 GTE and the BMW Z4 GT3 were also built under BMW Motorsport to compete in globally renowned racing competitions.
