BF Review: BMW Z4 28i (Return of the 4 Cylinder)

MotoringFile Sections: E89 Z4 Roadster, Review Aug 23rd, 2011 5 Comments

If the past 15 years have proven anything, it’s that BMW isn’t afraid of change. While design directions have gotten the most press, it’s BMW’s advances in engines that have excited us most. And no current BMW engine has more on its shoulders over the next few years than the N20 four cylinder under the hood of the Z4 28i.

We had an opportunity to sample the new Z4 28i on a day-long jaunt up the California coast to Speed Week at Monterey. We tested the car through the mountain roads of the Sierra Nevadas and California’s famed Highway 1. To call it the perfect test on the perfect day would almost be an understatement.

BMW’s New Four Cylinder: The Details

MotoringFile Sections: E89 Z4 Roadster, EfficientDynamics, Official News, Technology Apr 26th, 2011 7 Comments

We all know times are a changing; the age of horsepower wars and increasing performance through displacement is a closed chapter in the book of automotive history. Cheap and seemingly endless petroleum based fuels are really not so cheap these days and definitely will be approaching Mad Max like conditions sooner than many had originally thought. Greenhouse gas emissions threaten air quality and whether or not the climate is changing is a debate for another day but as a global society we are trying to get more from less in order to conserve what we do have. All of this has opened the eyes of auto manufactures and consumers, especially BMW through its Efficient Dynamics program and more recently introduced sub brand BMW i. Times have changed so drastically that BMW will now be selling four cylinders in the US again, something that has not occurred since the 1990′s.

The aluminum N20 four cylinder is so advanced and such a marvel it is not even worth comparing it to the previous stateside BMW offering. The N20 will feature a single dual scroll turbo taking gasses from opposing cylinders to force feed the engine air at 10-11 PSI. It produces 240hp and 260 ft/lbs. Staggering, but possible due to a number of key components- direct injection, variable valve timing and lift (VANOS and Valvetronic). It produces a whopping 120 hp per liter! Some of the intricacies that would go unmentioned by most is what we found the most interesting.

BMW NA Debuts the Four Cylinder Z4 28i

MotoringFile Sections: E89 Z4 Roadster Apr 18th, 2011 10 Comments

P90054118

After years of hinting at a four cylinder today BMW North America dropped one into an engine bay. And what a long and sexy engine bay it is. The E89 Z4 will be the first BMW in the US to have a four cylinder than the 318ti we wrote about this weekend. And with 240 hp and 260 ft lbs of torque it should have performance that rivals other 28i models in the BMW NA line-up.

Also tucked away in this release is the fact that this car will also come with BMW’s acclaimed eight speed auto available throughout most of the range. In total the auto and four cylinder combo (yes a manual is available) will give the entry level Z4 20% better efficiency than the Z4 30i.

Official Release: Following the announcement in February of the return of a 4-cylinder engine to the US BMW line-up, BMW today announced that the new 2.0-liter TwinPower Turbo 4-Cylinder will first power the Z4 sDrive28i that will arrive in BMW Centers this fall. Like the company’s latest TwinPower Turbo 3.0-liter turbo inline-6, the new 2.0-liter engine will combine highpressure direct-injection and BMW’s VALVETRONIC intake control (hence the name: TwinPower) with a forced induction system consisting of a single twin-scroll turbocharger. With 240 horsepower and 260 lb-ft of torque, it offers more power and torque than BMW’s normally aspirated 3.0-liter inline-6 that it replaces in the Z4 sDrive30i. (Video after the break)

Four Cylinders Make a Comeback

MotoringFile Sections: E36/E37 Z3 Roadster/Coupe, E89 Z4 Roadster, EfficientDynamics, Opinion Apr 16th, 2011 9 Comments

As BMWNA prepares for Monday’s relaunch of four cylinder motors in the US we wonder how the mainstream press and consumers will react.

You have to go back to mid-nineties ill received 318ti to find a four cylinder that made it across the Atlantic. By the time the 318ti came to market the US was in a state of relative prosperity and consumers wanted more. More refinement, more power and more luxury.

About BimmerFile

BimmerFile is dedicated to bringing you the most interesting news, links and reviews related to the BMW brand and it's vehicles.

We believe in the old school BMW ownership experience. We believe in garage nights with a six pack and some friends. We believe in 2002s, in E30 M3s and E34 540s with the 6 speed. We believe in progress in both design and engineering but we haven't lost sight of what made the brand and its products great all those years ago. And yes, we believe in the manual transmission.

We long for the days of the wave and for the days of roll-up windows. Yet we love the gadgets on the inside and the xenons on the outside.

In short, we can't get enough of BMWs. This is BimmerFile.
