BMW to Turbocharge its Entire Lineup of 4-Cylinder Gasoline Engines

Citing inside sources from BMW, British magazine Autocar is reporting that all of the Bavarian automaker's future four-cylinder engines will benefit from turbocharging technology. This includes all four-pots with outputs up to 245 horsepower, with the new straight-six engines taking over from there.

All of BMW's turbocharged four-cylinder engines will be built upon the same 2.0-liter aluminium block, with the difference in performance being made by using two different types of turbochargers and different engine mapping (apparently, BMW learned its lesson well from the VW Group...).

The aluminium block gets a new and very thin cylinder lining of only 0.3 millimeters thanks to the use of sprayed iron technology. That's a massive improvement over the classic 1.5 mm thick cast iron lining and it translates into less weight and more durability.

The most powerful engine, which will be soon available to order in the small X1 SUV under the xDrive28i badging, is a complex unit, having a double-sided twin-scroll turbocharger which works at pressures of up to 200 bar, double-VANOS variable valve timing and direct fuel injection.

Following lower-powered units are expected to get a single conventional turbo instead of the twin-scroll technology. The new turbocharged four-cylinder units will make their debut on the next generation of the 3-Series, expected in 2012.

New BMW Performance Kit Boosts 2.0-liter Diesel's Output to up 200HP

As well setting the stage for the world premiere of the Vision CD roadster concept and the production version of the pure-electric 1-Series ActiveE, the Geneva Motor Show will also see the launch of BMW's new Performance Power Kit for the firm's 2.0-liter turbocharged four-cylinder diesel engine found on numerous models including the 1-,3- and 5-Series range in both rear- and all-wheel drive configurations. The upgrade is available for both the previous 177HP as well as the newer 184HP 2.0L engine.

Thanks to an engine software optimization plus a larger intercooler and a more-efficient fan for the main radiator, output is lifted from 177HP and 350Nm to 197HP and 390Nm, and from 184Hp and 380Nm to 200HP and 420Nm, for each engine respectively. According to BMW, the acceleration from 80 to 120 km/h in 5th gear is up to one second faster after the conversion.

Buyers can also add BMW's Performance Sports Silencer that comes with two round, chrome plated 74mm tail pipes, and which in addition to optimizing exhaust back pressure, also offers a sportier sound.

Classic Ads: Why a Hyundai Excel is as Good as a BMW 325i

If this ad is to be taken seriously, the only difference between a late 1980s E30 BMW 325i and a Hyundai Excel is price and the engine / transmission layout. After all both have, “[A] plush interior, European styling [and] room for five.”

After all, niggling little details like equipment levels, brand image and build quality have never bothered car buyers before, right? Apparently not, as the Excel went on to become one of U.S.’s best selling imports, with 168,000 of the little blighters sold in its first year stateside. That’s a lot of, “Hun-days,” [sic].

So what if it had the looks of a three-year-old Toyota Corolla and was built in a place that wasn’t even a country sixty years ago; it cost just US$5,499 and in salesman speak that’s a damn good deal. There are probably innumerable benefits to owning a 1988 Hyundai Excel. Such as...uh...or maybe...um...and then there’s...oh.

It was cheap, yeah? And cheap is good despite what a certain fictional character may have said to the contrary. That’s true for at least the vast majority of cash-strapped Americans and almost certainly for Hyundai. Yes, it was front wheel drive and sure it had no outstanding qualities other than the price tag. The same could be said for many of the cars sold today, and you don’t see any of them comparing themselves to a German heavyweight.

So watch the ad and reminisce about a simpler time when men wore pinstriped shirts, martini lunches were often followed by cocaine afternoons and a balmy little upstart from the Sea of Japan had the verve to stick its fingers in its ears and stick its tongue out.

Official: BMW 2.0-liter Turbo Coming to the USA in 2011, Replaces 3.0-liter Straight-Six

We knew BMW's brand-new 2.0-liter turbocharged four-cylinder engine was coming to the States but now, the Bavarian automaker has made it official. The German company released a statement saying the first cars to be equipped with the force-fed four-banger will "arrive later this year" in the USA.

The 2.0-liter unit made its debut on the X1 compact crossover and will eventually replace BMW’s trademark normally aspirated 3.0-liter inline six. While BMW's US division has yet to announce which models will get the new engine, in Europe, the automaker has already confirmed the powerplant for the Z4 coupe-roadster and the 5-Series range.

In the U.S., the naturally aspirated 3.0-liter inline-six is currently available on these models:

-128i Coupe / Convertible 230HP

-328i Sedan / Coupe / Convertible / Sports Wagon / xDrive 230HP

-528i Sedan 240HP

-X3 xDrive28i 240HP

-Z4 sDrive30i 255HP

There's a strong possibility that BMW will offer the new 2.0-liter turbo on all of these models in the U.S. but this has yet to be confirmed.

BMW's more for less 2.0-liter unit combines twin-scroll turbocharging with high-pressure direct-injection and the firm's VALVETRONIC intake control. In the X1, the maximum output of 240 horsepower is achieved at 5,000 rpm, or 1,500 rpm lower than in the normally-aspirated 3.0-liter inline six. The peak torque of 260 lb-ft, comes on tap at just 1,250 rpm, which according to BMW, is not only 30% more torque than the aforementioned inline six, it also peaks 1,500 rpm earlier. On top of that, BMW says the four-pot also returns 16 per cent better fuel consumption and lower CO2 emissions.

New Rumors Surface about 4-Cylinder Turbocharged BMW Engine, this time for Z4 Roadster

Last time we reported about BMW's long-rumored family of turbocharged 4-cylinder engines, it was in the summer of 2010. Meanwhile, the German manufacturer hasn't revealed anything on the matter, giving the whole affair an almost mythical status.

However, a new rumor has surfaced, with Automobile Magazine tweeting that the entry level BMW Z4 will soon get a new, 4-cylinder force inducted engine, as a replacement for the naturally aspirated inline-six.

The exact tweet was “BMW new 4-cyl coming this year in Z4 roadster. Replaces nat asp 6, so at least 200 hp” and, seeing that average fuel consumption regulations and emissions standards are getting stricter by the day, it sounds like a logical move for BMW.

The Bavarian company sure knows how to build a fine turbocharged engine and there are many models in its line-up that could benefit from a more frugal, and equally if not more powerful four-pots. The 1-Series and 3-Series are just two that come to mind right, although we’re pretty sure that X3 owners wouldn’t mind better fuel economy as well.

Clearly, the question here is not “why”, but rather “when”, and at the rate things are going, we’d say let's meet up again this summer and we’ll hopefully have some more official info for you.

U-SPY: Carscoop Reader Snags a Fleet of BMW Prototypes in Austria

The BMW Group is quite busy these days as the Bavarian automaker is developing a raft of new models, ranging from the upcoming Megacity electric-vehicle and the MINI Coupe and Roadster, to the next generation of the 3-Series and the production version of the Vision ED concept sports car.

Carscoop reader Andras from Hungary was vacationing in Obertauern, Austria when he spotted this convoy of BMWs comprising of both masked prototypes and normal production cars, including a sedan in full body cladding. Check out Andras' photos and story after the jump.

Andras Deak's Scoop:

"I am currently in Obertauern, Austria for my holidays and discovered a small parking place dedicated to BMW. I walked there to check the cars and took some pictures.

There were 4 "cooling boxes" for cars. At the parking area I recognized a heavily camouflaged next-gen BMW 3-Series (possibly a hybrid version), the brand new X3 with some light camouflage (also possible hybrid version) and several 5-Series... Note that all the cars were plugged into something which looked like an electric charger to me.. Maybe a plug-in hybrid?

The interior of the next-gen 3-Series looks like all the new BMWs these days. It looked like a small 7-Series from the inside. The navigation screen is huge. I could see several fingerprints on the screen (maybe touchscreen?), but also an iDrive controller..."

Köszönöm for the pictures Andras!

G-Power Transfers BMW M5 Hurricane RR Supercharger Tech to the E85 Z4 Roadster

German tuner G-Power has decided to share some of the technology found on the 800-horsepower M5 Hurricane RR and M6 Hurricane RR with the masses by offering a modified version of the supercharger system on the [previous generation] E85 BMW Z4 as well as the E46 Series with the 3.0-liter straight-six engine. On both models, the redesigned SK Plus supercharger system replaces the previous ASA TM3 supercharger.

The geometry of the compressor has been modified as has the housing, resulting in a more efficient build-up of boost in the middle rev-range. With a 0.3 bar pressure boost, the SK Plus kit increases output by 55 ponies, to 286 hp and 345 Nm (255 lb-ft). Thanks to the extra oomph, the tuned Z4 accelerates from standstill to 100 km/h (62 mph) in 5.4 seconds.

To be able to wring out every bit of performance delivered through force induction, the German tuner recommends customers to specify their cars with a 9-way adjustable coil-over sport suspension. 20-inch multi-spoke Silverstone Diamond alloys, wrapped around in 245/30 front and 285/25 rear Michelin tires, can be ordered, too. For a more ferocious roar, G-Power can provide a new, hand-built rear silencer, with matching tail pipes.

Granted, these changes don’t transform the Z4 SK Plus into a Hurricane killer, but the tuner charges only €2.500 (VAT excluded) for the performance upgrade, which as we mentioned previously, is also available for the E46 BMW 3 Series.

Prior Design Releases Widebody Kit for the E92 BMW 3-Series Coupe

German tuning firm Prior Design has unveiled a widebody kit for the E92 3-Series Coupe, which turns the bimmer into an M3 clone with a "hormonal disposition" [whatever that means...], for a base price of €2,999. While we're not sure about those "hormones", the exterior modifications look nice enough, so Prior's kit is definitely worth a look.

The body kit fits all E92 Coupes, except, of course, the genuine M3, and is a new development manufactured from Duraflex, "a very flexible and extremely stable material", according to the company.

Designers scrapped the old front bumper and fitted the car with a new piece featuring larger air intakes. They also changed the bonnet, but didn't go for the stock M3 look. Instead, they emulated the look of the M3 GT2 racecar's hood with integrated air vents.

Lowered side skirts continue the front's muscular look, alongside the widened wheel arches. At the back, you can find a new bumper complete with a diffuser, which can accommodate the M3 exhaust system and all E92 Coupe tailpipes, minus those found on the 335i. The latter can be opted with a specially designed stainless steel exhaust system, also mimicking the M3, priced at €1,499.

Furthermore, the body kit comes with boot-lid and roof spoilers, both of which are also available in carbon fiber.

An adjustable KW coil-over kit that lowers the car's ride height for a more aggressive stance, rounds off the package.
