The BMW Z4 is a rear-wheel drive sports car that began its life back in 2002 before receiving its second generation in 2008. It is offered in both coupe and roadster forms. The current model Z4 is powered by a choice of two engines. The first is a 3.0L I-6 producing 255hp and 220 lb-ft of torque, while the second is a 3.0L twin turbo I-6 producing 300hp and 300 lb-ft of torque. These engines are mated to a six-speed manual, a six-speed automatic, or a seven-speed automatic transmission.

The BMW Z4 and Nissan 370Z are both dream cars. And Fifth Gear had the chance to place them face to face. Japanese technology vs. German technology tested by the British press. Sounds interesting, no?

Fifth Gear tested the BMW Z4 sDrive35i, a model powered by a twin-turbo inline-six cylinder engine that develops a total of 300 Hp. It makes the 0 to 60 mph sprint in 5.1 seconds, while top speed is limited to 130 mph.

The Nissan 370Z is powered by a VQ37VHR 3.7 Liter V6 with VVEL rated at 332 HP and 270 lb-ft of torque. It makes the 0 to 60 mph sprint in 4,7 seconds and top speed is limited to 155 mph.

So, at first glance, the 370Z seems to be a better choice, but what did the British magazine think? Check out the video to find out!

Try stealing this one. C’mon, we dare you. Not only will you be having trouble boosting it without anybody noticing, but the mere thought of moving this BMW Z4 is enough to make even the most desperate of crooks think twice about getting near it.

Of course, it helps that this Z4 is made of stone.

Found in Beijing, this incredible one-of-a-kind stone replica of a Z4 is about as intricate as it can get. How so, you ask? Well, the car’s interior is even decked out in all its intricacies.

Somebody really went out of his way to make this, proving that in China, there’s nothing that these guys can’t do.

When does anyone get to see a German model tuned by a Japanese tuner? Apparently, the answer is today. 3D Design is offering a pretty impressive package for the new BMW Z4 Roadster , even if their only focus is on improving the exterior.

The exterior package includes a new front lip spoiler and a trunk spoiler both made of urethane and a rear diffuser made of carbon fiber. The Z4 is audibly improved with the use of 4-tip exhaust. The package is finished by that impressive black exterior color making this vehicle look as if it was made for a man’s man.

Although the BMW Z4 does look the part of a mean road racer, unfortunately the lack of turbo boost leaves it a little on the weaker side of the roadster warrior spectrum. For any of the gladiators out there that need a little power along with the vision, try taking a look at the Hamann package for the Z4.

Katarina Witt, the BMW Group’s Olympic ambassador, took an exclusive look behind the scenes of the new Energy and Environmental Test Center and didn’t waste the opportunity to shoot a few photos with the new Z4 Roadster .

The test center is used to test cars in all weather conditions: sun, rain, ice and snow: "Here, we test extreme heat levels of around 45°C on cooling systems, air-conditioning and engines in order to reproduce conditions in a Middle Eastern summer, for instance. Since we’re able to adjust climatic parameters more precisely at the test facility than on the street, this makes for very precise results. This helps us design our engines and cooling systems in such a way that they deliver optimal performance while simultaneously reducing energy consumption. Perfectly in line with BMW Efficient Dynamics."

The 2010 edition of the Mille Miglia is particularly important because BMW is celebrating the 70th anniversary of the historic victory of the House at the Brescia Mille Miglia. And what better way to celebrate than launching a special edition Z4? Called the Z4 sDrive35is Limited Edition Mille Miglia (yes, it is an annoyingly long name), this special edition will be limited to only 99 units.

The BMW Z4 sDrive35is Limited Edition Mille Miglia will be painted in a Polaris Metallic matte finish with a black front grill. It will be offered with an M aerodynamic kit, ‘Mille Miglia’ badges, and 19-inch wheels finished in Dark Chrome.

The interior will get leather and Alcantara with red stitching and M sports steering wheel with the same red stitching.

Under the hood the same engine will be utilized as in the sDrive35is: 3.0-liter 6-cylinder twin turbo engine that delivers a total of 340 hp and 450 Nm of torque. The top speed is still limited to 155 mph.

This is a pretty cool video presenting the BMW Z4 GT3 at Nurburgring with Richard Goransson behind the wheel. It’s not just like every other video showing the car racing around the track. This video provides an in-car perspective with the use of a videocamera mounted inside the car. The sounds of the car are a little high-pitched and eerie, but the sights are pretty decent.

The BMW Z4 GT3 is powered by a 4-liter, eight-cylinder engine equipped with a 408 ECU and a Power400 control unit. The engine delivers a total of 480 bhp and is mated to a sequential, six-speed gearbox.

The German tuner, Hamann, revealed today the official details on their first tuning kit based on the 2010 BMW Z4 Roadster . The kit includes both aerodynamic and performance upgrades which, to put it mildly, blows the kit by Hartge out of the water. This kit provides us with a cleaner, smoother line and a jump in horsepower.

For the exterior, Hamann added a new front spoiler with two integrated LED day lamps, side skirts, a shapely spoiler mounted on the tailgate, a new rear apron, and a sporty four tailpipes exhaust system. The Z4 sits on 20" forged wheels painted in matte black.

Under the hood the engine has been tuned to deliver 360 HP at 5230 rpm and a peak torque of 540 NM available in the engine speed range of 1300 to 5000 rpm. The speed limit has also been removed (YES!!) so that now the Z4 can go up to 177 mph.

For the interior you can also get a new aluminum gear knob and a set of foot mats with the silver stitched Hamann logo.

Now, this is an appropriate kit for the BMW Z4 Roadster!

Press release after the jump.

The German tuner, Hartge has revealed a new aerodynamic kit for the 2010 BMW Z4 Roadster again. As you may recall, Hartge previously released a kit for the Z4 in January 2010 that included a buffet of options. This next kit, although slightly impressive as well, left us hungry for more and not because it was delicious, but because it was lacking substance. Based on the E89 roadster, the kit for the BMW Z4 will include a new front spoiler and lip for boot lid both made of PU-RIM. That’s it. There’s nothing else. None of these new parts are compatible with the M Aerodynamic package and prices for the kit have not yet been announced. Throw us a bone, Hartge.

You may have to pay a doozy to be able to bring a high-powered race car to the 2010 VLN season but as auto scribes would tell you, that’s the price for being competitive.

Schubert Motorsport, a German racing team, is scheduled to compete in the VLN this year and they’re shelling out over $400,000 for a BMW Z4 GT3 . Powered by a 4.0-liter V8 engine that produces over 480 horsepower, the BMW Z4 GT3 is a certified beast on wheels. How it fares against the competition, though, is an entirely different matter.

Nevertheless, Schubert Motorsport took their prized racer to the Nurburgring where driver Richarad Goransson took it for a flying lap around the Green Hell. The car’s not as quick off the block as the M3 GT2 but that’s more a case of following racing regulations set forth by the FIA for the GT3 classification.

Either way, check out this video as Goransson takes the Z4 GT3 out for a flying lap in Nurburgring. Then you can decide if the car is up to pace for a GT3. As far as we’re concerned, it looks like it can bust a few challenges on its own.
