Review: 2012 BMW Z4 sDrive28i

Posted on 14. Jan, 2012 by in Auto News

Now that winter weather has (finally) come to Michigan, it's time to look forward to spring, when roadsters emerge from their long winter frolic along twisty two lanes. Did I not see and feel the urge? More than a midsize sedan or a compact crossover, a roadster is a very personal choice, as a candidate, Audi TT, BMW Z4, Chevrolet Corvette, Mazda Miata, Mercedes SL and SLK, Nissan 370Z, Porsche Boxster-vary in configuration and character much more than in the high-volume segments. If you know what you want in a roadster, the choice is doing himself. So, what could cause someone decided to BMW?

The Z4 is an oddball in the BMW line. While other BMWs are very similar, often styled in a failure, the Roadster is clearly not like the others. No "same sausage, different lengths" here. Yes, it's more of a similarity than with the full-on retro Z3, which originated the model. But while secondary signals now resemble those of the other BMWs, the Z4 remains bulldog proportions of a classic roadster. While stopping well short SLR surplus could cover even induce envy of John Holmes. In comparison, continues to appear the hindquarters disproportionately small. When the roof seems to be undersized, also is little, although the need to have it fit inside the compact trunk have as much of an aesthetic factor.

Inside, the car typically BMW, including an unfathomable audio system, although some indications remain on the Z3. From the low-mounted driver seat long hood actually seems to get up in front of you, greatly impairs the driving experience. SUVs and even ordinary cars tower over you. You know you drive a sports car when stopped. You did not get even remotely in a 3-series, or even in an otherwise similar SLK. Unlike some of the Roadster header is not too low, and not so uncomfortable encounter by looking forward.

There's plenty of headroom. The seats offer good lateral support, but as the series insufficiently cosseting seats in other BMWs are otherwise only marginally comfortable despite four-way lumbar adjustments. Even with the top stowed, there is enough room in the trunk for a Costco run (including a value pack paper towels) or for a few weekender-sized suitcases.

The Z4 habitability in even further progress. Noise level is moderate, and the ride is quite livable (though it can get choppy over tar strips and expansion joints). This roadster is far from raw. If you want your BMW raw, find a Z3, preferably in M Roadster form.

But it's fun? After all, it is for a roadster is fun to drive, then what is the point? (Okay, some people buy these items only for styling and image, but I'd rather not fool me.) Assessment 2012 BMW Z4 is the sDrive28i. If you do not speak BMWese means by it's rear-wheel drive (the Z4 is available with all-wheel drive, at least not yet) and driven the equivalent of a 2.8-liter direct injection engine. Why the italicized bits? As CPU manufacturers, BMW went from a literal representation of important specs when it threatens the revenue by two engines seems hurt either too close together or too far apart in performance potential. For 2012, the 2.8 is actually a new turbocharged 2.0-liter four-cylinder engine instead of the last year 3.0-liter inline six-cylinder. To its 5,000 rpm peak full 2,000 rpm short of redline-deletes the four 240 hp. How many current turbocharged engines, the torque is managed electronically, a not-yield curve flat as Kansas, with 260 pound-feet. All the way from 1250 to 4800 Based on the low-power peak, there is a lot of headroom left in this engine. BMW has tuned it to fill in the workhorse six that previously driven her models' lower trim levels, not to offer high speed thrills. Aftermarket tuner will no doubt do what BMW did not, and boost this motor past, perhaps even earlier 280 hp.

And driving behavior, which was clearly a priority? I often have the feeling that feels even a decent and six sounds better than a very good four. But while the voice of the new BMW four never to one of his trademarks inline sixes be confused, that does not sound like the typical four-banger, either. Instead, perhaps because of the exhaust design for the twin-scroll turbocharger (with two cylinders feeding each "scroll"), it sounds surprisingly like a boxer up to 4,000 revolutions per minute. Not as sophisticated as a six, but sports and decidedly less pedestrian than a conventional four. I enjoyed listening to them. Start at higher revs the engine actually do something like a six sound. The conservative mood, modest amount of boost and twin-scroll design conspire to Boost was minimized, so that apart from the occasional howl of the engine is not obviously enhanced. In casual driving it performs very well, and should even up to the task, the motivation of the quarter-ton heavy 528i (the £ 3,800 I have not tried yet).

Still, you can not fool the early peak and broad plateau of the torque curve. All of the engine torque may (or may not, the BMW may have loose connection with reality given to official figures) to be present at 1,250 revolutions per minute, but it still is not much grunt down there. After all, power is multiplied by engine speed and torque just above idle there is not much of the past. To real power from the engine, wrap it to 4,000 revolutions per minute, beyond which point it pulls hard pleasing. Just not for long. With 6,000 rpm the engine runs out of breath, and you might as well move, even though the engine remains smooth for a different wing.

Actually, you should move the six-speed manual transmission. The shifter throws ended the moderate in every gear with a
