BMW Z4 getting a facelift by 2012

BMW announced that the Z4 will get a facelift by 2012. The details have not yet been disclosed but the roadster will definitely have a new powerplant to add some oomph into its performance.

In the US, the BMW Z4 comes in three versions: Z4 sDriveis, Z4 sDrive35i, and Z4 sDrive30i. The sDriver30i depends on a 3.0L inline 6-cylinder powerplant that gives out 255 horsepower. This will change next year with the BMW Z4 getting a 4-cylinder turbocharged engine to replace the six-cylinder powerplant. Insiders say that the new engine will deliver the same power as the old engine. The BMW 328i is also getting this 4-cylinder engine.

The German carmaker is not implementing major changes for the Z4′s interior and exterior. However, there are some rumors that it will borrow some elements from the CS Concept unveiled back in 2007.

The entry level Z4 will have a 4-cylinder heart giving out 255 horsepower for its 2012 upgrade but the output is expected to be pegged still at 255 horsepwoer. The sDrive35i will still depend on the inline six-cylinder powerplant with an output of 300 horsepwoer. Top speed will still be at 155 mph.

The 2012 Z4 is expected to debut before the end of the year but sales will start on the first quarter of 2012. The current model has a sticker price of $46,500 for the entry level Z4 and we can expect the 4-cylinder BMW Z4 next year to have a cheaper tag price.
As we predicted in the past, the first BMW in the United States to feature the new N20 four-cylinder TwinPower engine is the BMW Z4 sDrive28i. We also anticipate that the BMW 528i will receive the same engine this fall.
“The new BMW Z4 sDrive28i Roadster will be the first model in the U.S. to feature the company’s new powerful, efficient and clean TwinPower Turbo 4-cylinder engine. It also marks the return of BMW 4 cylinder power to the United States for the first time in over a decade.
This newest engine, another part of the company’s on-going development of BMW EfficientDynamics, is the latest to combine twin-scroll turbocharging technology with high-precision direct injection and BMW’s Valvetronic throttle-less control system. Taken together, these technologies improve performance while at the same time reducing emissions and lowering consumption.
With 240 horsepower and 260 lb-ft of torque, this new engine offers similar  power to the normally aspirated 3.0-liter inline six currently offered in the Z4 Roadster and more torque..

Maximum output of 240 horsepower is achieved at 5,000 rpm, 1,500 rpm lower than in the normally-aspirated 3.0-liter inline six. The peak torque of 260 lb-ft comes on stream at just 1,250 rpm. Not only is that nearly 20 percent more torque than the aforementioned inline six, it also peaks 1,500 rpm earlier.  The new BMW Z4 sDrive28i will arrive in US showrooms this fall.”
It’s old news that the BMW 2.0-liter turbocharged V4 engine is in the works and on its way route to the U.S. market. But then, the Bavarian car company has made its official announcement about its arrival. BMW has recently issued an official statement confirming that the first batch of BMW units that carry the said 2.0-lited turbocharged V4 engine will roll into the US market some time during the latter part of the year.

The turbocharged BMW engine was first presented attached to the X1 compact crossover and is said to replace the brand’s trademark 3.0-liter v6 engine. The carmaker’s American arm has yet to release the actual models that would carry the new 2.0-liter turbocharged V4 engine. However, its European arm has already released the BMW’s 5-Series Range and the Z4 coupe-roadster are included in their lists.

The trademark BMW 3.0-liter V6 engines are attached to the following models: the Z4 sDrive30i with 255HP, the 528i Sedan with 240HP, the X3 xDrive28i with 240HP, the 128i Coupe and Convertible with 230HP, and all the versions of the 328i xDrive with 230HP. It is speculated the same roster of BMW models will also carry the new 2.0-liter turbocharged V4 engine.

The new engine comes with both the power of “high-pressure / direct-injection” system and the VALVETRONIC intake mechanism. The turbocharged X1 model has 240 horsepower and 5,000 rpm with a maximum torque of 260 lb-ft. BMW claims that the new turbocharged V4 engine is 16% better when it comes to fuel efficiency.
