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.

Just as BMW promised back in February, they have arrived at the 2011 New York Auto Show with the return of a 4-cylinder engine to the US line-up. The first vehicle to benefit from this new engine is the Z4 sDrive28i. This new model will go on sale this fall and will replace the Z4 sDrive30i (pictured).

The new 4-cylinder engine delivers a total of 240 HP at 5,000 rpm and a peak torque of 260 lb-ft at only 1,250 rpm. This power will allow 30% more torque than the inline-six engine and achieves 1,500 rpm earlier.

The 4-cylinder engine features an all-aluminum crankcase and is lighter and more compact than a 6-cylinder engine. The turbocharger is a twin-scroll system. The exhaust streams out in two separate pairs of cylinders, flowing through the exhaust manifold and the turbocharger, then circulating to the turbine wheel.

The new Z4 sDrive28i will be offered with an eight speed automatic transmission and will offer a fuel efficiency gain of approximately 20% over the naturally aspirated engine it replaces.

UPDATE 08/22/11: BMW has released a new promo video of the Z4 sDrive28i as its being driven around Grimes Canyon. If you ask us, the car looks great!

In the year since BMW Motorsport launched the 2010 Z4 GT3 , the race car has achieved great success in the GT3 class series, including a ground-breaking win at the Dubai Dubai 24 Hours earlier this year. But despite the car’s competitiveness, BMW knew that it still needed a few improvements. So, the Bavarian automaker let loose and built the new and improved 2011 Z4 GT3 racer.

According to BMW, the goal for the latest version of the Z4 GT3 racer is to primarily improve its aerodynamic efficiency to make it more competitive against its rivals in the GT3 class.

Noticeable improvements done on the new version include an elongated bonnet, a long wheelbase, and the narrow wheel arches. The car was also given a steel body courtesy of the BMW plant in Regensburg, Germany and a safety cell made of sturdy steel tubing that’s welded into the body. Likewise, BMW made good use of carbon fiber reinforced plastics, dressing up the car with the strong yet lightweight material on the front and rear wings, the bonnet, roof, and fenders, among other components.

Another difference between the standard road-going Z4 and the racing variant is the powertrain. Whereas the former came with a six-cylinder engine, the latter was given a more powerful 4.4-liter V8 engine mated to a six-speed sequential gearbox.

The car is now being sold to racing teams for €315,000, which is about $454,000 based on current exchange rates.

Now that the 2011 Geneva Motor Show has come and gone, it goes without saying that the event was arguably the biggest and most successful auto show since the 2009 IAAs in Frankfurt, Germany.

Some might contend that, but as far as we’re concerned, its been a while since we had an auto show that has been as widely attended by almost all automakers in the world quite like what we saw in Geneva.

And while we may have been introduced to a lot of the cars that were launched in Geneva beforehand, there were still some models, mostly of the concept variety, that took us by surprise.

Most of these models weren’t previewed before the event so when the Geneva Motor Show opened its doors, just about everybody in attendance and those keeping tabs over the Web didn’t see these cars coming.

But now that they’re here, we can take a look at the models that made the 2011 Geneva Motor Show that much more interesting.

After their last one-off project - the golf club-inspired BMW Z4 ‘Slingshot’, which received great acclaim - it seemed like it was just a matter of time before the people of MWDesign Technik would return for yet another tasty dishing of a one-off BMW Z4.

Apparently, these guys are true to their word.

Inspired by the work done on the Slingshot Z4, a client of MWDesign requested the tuning firm to work their magic on his brand new BMW Z4. Not one to turn down an opportunity, the boys from MWDesign took the offer and began working their magic.

Just like the “Slingshot” Z4, the BMW Z4 “White Flame” draws inspiration from another golf club, the Taylormade R-11 driver. In designing the car, MW Design made sure that it translated some of the key design cues and coloration of the club into the car. Seeing as the R-11 features a white, red, and gray theme, MWDesign decided to put in the same color scheme in the Z4, albeit in a subtle fashion to maintain the car’s sleek and clean look.

Next to the impressive Vision ConnectDrive concept , BMW has also revealed an impressive package for the BMW Z4 at the 2011 Geneva Motor Show. Called Design Pure Balance, the new equipment package comes with striking interior and exterior options, and will go on sale in the summer of 2011.

The BMW Z4 Design Pure Balance is painted in a Mineral White metallic finish offered exclusively for this package. This color offers fine metallic pigmentation for a brilliant impression. However, if the white metallic hue doesn’t tickle your fancy, the new package can also be combined with other non-metallic and metallic exterior paint finishes.

Typically, a white exterior look is combined with a black interior, but BMW has gone against the grain with Cohiba Brown leather contrasted by Lotus White stitching for the seats and the same Cohiba Brown for the dashboard. Black isn’t far behind, though, as the rest of the leather trimmed elements are found in black with Umbra seams. Fineline Anthracite wood and sports seats come standard with the package.

With a name like Design Pure Balance, there is no way BMW would think to touch the inner mechanical workings of the Z4. That leaves us with the standard 3.0L I-6 engine producing 255hp and 220 lb-ft of torque.

Now if only the BMW Z4 Design Pure Balance came with Cohiba brand premium cigars. Then we’d be in business!

The Geneva Motor Show is ready to crack itself open in just a few hours, but AC Schnitzer has decided to release some details on its line-up for Switzerland a little early.

The first package from the German tuner is called the Z4 99d and uses a diesel engine that delivers 190 HP and 420 NM of torque. With this amount of power, plus a weight reduction of 230 kilos (507 lbs.), the tuner has managed to obtain a 0 to 60 mph sprint time of just 6.9 seconds, while top speed is 146 mph. This performance is accompanied by a fuel consumption of 3.8 liter diesel per 100 kilometers and a CO2 emission of just 99.18 g/km.

AC Schnitzer also spent some time on the exterior of the BMW Z4 with an interesting paint job. We don’t know just how we feel about the green, blue, and black swirl paint yet, but it may just fit the BMW nicely.

UPDATE 02/28/2011: This review has been updated with the BMW Z4 99d’s full specs, as well as new images.

The BMW Z4 may have waited seven years between its first and second generation, but the two-door roadster will be seeing a few updates come 2012 when its scheduled to get a minor facelift at its early age. As of now, there isn’t a lot of talk about exterior or interior updates, but the inner workings of the Z4 will surely get a dose of modernization with a new engine.

The current US line-up for the Z4 includes three models: Z4 sDrive30i, Z4 sDrive35i, and Z4 sDrive35is. The entry level model is powered by a 3.0-liter, inline 6-cylinder engine that delivers 255 HP, but that will be changing next year when the six-cylinder engine is dropped in favor of a turbocharged four-cylinder powerplant. BMW has promised that this new engine will deliver the same amount of power as the engine it replaces. All that says to us is that the difference will be completely auditory as turbocharged engines always sounds better. This four cylinder is rumored to plant itself in the BMW 328i as well.

A few months ago G-Power unveiled the Hurricane RR - the world’s fastest sedan. Now, in an attempt to make the BMW Z4 even faster, the tuner is offering the same SK Plus supercharger system for the sports roadster.

This system is available for the Z4 3.0i version and increases the engine’s output by a total of 55 HP. The result is an impressive 286 hp at 6,000 rpm and 345 Nm of torque at 3,500 rpm. With the new supercharger, the Z4 will now sprint from 0 to 60 mph in 5.4 seconds.

Next to this system, G-Power is also offering a new set of 20" wheels, a “GZ4-RS” coil-over suspension with 9-way adjustable compression and rebound, and a rear sport silencer made from stainless steel.

The price for the package is 2,500 euro and can also be applied to the BMW 3 Series E46. However, if you are looking for some serious power then potential customers should also take a look at the BMW Z4 by Hamann . This kit provides the roadster with 360 kicking ponies and strips away the top speed limiter. Really the preference between these two models comes down to customer preference. Subtlety and style goes to G-Power while speed is a hands down win for Hamann.

Press release after the jump.

Living in Japan has always had its perks. There’s the beautiful weather, the delicious tempura prawns, and if you’re a fan of BMW , the exclusive BMW Z4 Roadster Silver Top Edition.

The Z4 Roadster Silver Top Edition is the latest Z4 special edition to come out of BMW, and it will not be available in this part of the world. Guess we’ll just have to settle for posters on our walls.
