AdBlue technology by BMW: reduced emissions without additional service appointments
The active tank is connected to a second reservoir, the so-called passive tank. With its additional capacity of approximately 4.5 gallons, this passive tank offers a plentiful supply of the urea solution required within the car. The average range provided on this supply capacity is indeed sufficient to have the tank system replenished as part of normal scheduled maintenance.
From the active tank AdBlue is delivered to the dosing valve and atomized into the exhaust emissions. Consistent distribution of AdBlue within the flow of exhaust emissions is ensured by the SCR mixer. The ammonia generated in this way in the hot emission gas subsequently acts in the SCR catalyst as a reduction agent and converts environmentally harmful nitric oxides into nitrogen and water vapor in a process referred to as selective catalytic reduction.
This process gives the special SCR catalyst its name with the SCR system as such being masterminded by highly efficient engine management. A nitric oxide sensor, finally, provides information on the concentration of NOX in the exhaust emissions.

Most advanced exhaust gas management: SCR catalyst with AdBlue injection
BMW has developed a two-tank system for AdBlue ensuring convenient use of this new technology with all the benefits and ease required by the customer: The amount of AdBlue required in each case is drawn from the active tank comprising approximately 1.6 gallons by means of a dosage pump. And since the urea solution would freeze at a temperature of −11oC, this active tank, as well as the dosage pipes are heated.
The new 335d Sedan: power, torque and remarkable fuel efficiency. All with refinement and sound worthy of a BMW
In Europe, where fuel prices have historically been – and remain – much higher than in the U.S., vehicle manufacturers have achieved dramatic gains in the performance, smoothness, quietness and emission control of diesel engines…while maintaining the diesel’s historic superiority in fuel efficiency. Now, with the new 335d Sedan, BMW brings this progress to the U.S., with brand-new technology that meets the U.S.’ strictest emission standards.
Like all ’09 BMW gasoline engines, the 335d’s new diesel is constructed with a weight-saving aluminum cylinder block – something that’s not taken for granted given the diesel’s much higher compression pressures. (All BMW engines have aluminum cylinder heads.) It is an inline 6-cylinder engine maintaining a defining BMW tradition that means exceptional smoothness and unique sound.
In addition, several diesel-specific technologies of this new engine contribute to its achievement of true high performance, diesel fuel economy and clean exhaust:
Common Rail (CR) means that a single, very high-pressure fuel-delivery pump supplies all cylinders, the fuel traveling along a common “rail” or distributor line. From there, fuel is injected at extremely high pressure (1800 bar/2645 lb./sq in.) directly into the cylinder.
The basic novelty of common-rail injection was to divorce the production of fuel pressure from the actual injection process; this was necessary to give the diesel engine what gasoline engines have long had, namely completely electronically controlled fuel injection. CR also facilitates multiple injections per combustion cycle. In all, this was a breakthrough that made possible dramatic strides in diesel power, efficiency and emission control.
Piezo injectors. A further breakthrough, already applied by BMW in the 335i (and other BMWs) models’ twin-turbo gasoline engines. With direct injection, the injectors – that critical component injecting fuel into each cylinder’s combustion chamber – are subject to especially high temperatures and pressures. Instead of most injectors’ conventional electrical valves, a “stack” of piezo crystals reacts lighting-fast to impulses from the engine electronics governing the injector needle’s opening stroke and duration for ultra-precise control. This, too, facilitates major advances in fuel economy and emission control, in gasoline, as well as diesel engines.
At low engine speeds, intake air does pass through the large turbo, but it’s the smaller, lower-inertia one that does the air compressing (turbocharging). Thanks to its optimum efficiency within this rpm range, it provides effective boost for driving from a standstill up to modest acceleration rates and driving speeds. So it is that this engine develops a good 390 lb-ft. of torque at as low as 1500 rpm – a remarkable achievement that will amaze first-time 335d drivers and continue to thrill those who drive this BMW regularly.
With increasing engine speed, the larger turbocharger begins to take over: first as a pre-compressor for the smaller one, then progressively until it becomes the primary turbo. The engine reaches its maximum of 425 lb-ft. by 1750 rpm, and then maintains this immense torque level until 2250 rpm going on to reach its peak power of 265 hp at 4200 rpm.
Diesel combustion, power and torque characteristics. In its most basic distinction from gasoline engines, a diesel engine achieves its combustion not with a sparkplug, but by much “harder” compression of the fuel-air mixture; the 335d engine, for example, has a compression ratio of 16:5:1, vs. 12.0:1 in today’s ultra-high-performance BMW M gasoline engines and the 10.2:1 of the 335i twin-turbo gasoline unit. For one thing, this requires a significantly stronger engine structure; indeed, the 335d engine weighs more than its 335i counterpart.
Diesel engines also employ a different fuel, the product of a different refining process from that of gasoline. The two fuels are not interchangeable; gasoline cannot be used in a diesel engine, and vice versa. Their prices typically diverge; at any time or in any location, demand may be different for the two, and government taxation policies for gasoline and diesel fuel also diverge.
Stellar pulling moxie, full-bore acceleration – and fuel efficiency. The huge torque output of 425 lb-ft. at relatively low engine speeds speaks for itself; 335d drivers will marvel at this engine’s robust response at low to medium speeds. The peak power output of 265 hp also speaks for itself, as does the resulting 0-60-mph time of 6.0 sec. While official EPA mileage estimates are not yet available, preliminary tests indicate 23 mpg city and 33 highway.
Sporty BMW X4 based on the X3 in the works
According to Autocar, BMW is working on a sporty version of the X3, which will be called the X4. Apparently, the Bavarian car maker wants to repeat the X6 recipe with the X4 (you take a popular SUV, create a sporty version of it and then let money come to you). Scheduled to go on sale in 2014, the X4 will be a four-seater (just like the X6) and BMW even consider an M version of the model.
It looks like the X4 idea isn’t new, BMW designers proposing a sporty X3 back in 2003, but due to capacity concerns at the company’s factory in Magna, Austria the project was postponed. Now, with recent investments at the Spartanburg plant in the US which will extend production from 160,000 to 240,000 units per year, it looks like the X4′s chances of ever seeing daylight are pretty high.
According to Autocar, when asked about the X4, a “high-ranking BMW official” told “With the move into North America, we’re able to take advantage of greater production flexibility,”, which is a pretty affirmative answer.

New Porsche Cayenne Turbo Gemballa tunning
Supporters of the anti-SUV campaign are probably not familiar with this new GEMBALLA conversion, titled simply Tornado GTS and GTR. If they were, they could be converted into SUV activists in an instant. The vehicle is based on the Porsche 957 and the characteristics of power previously reserved to the gates of razor supercars type. In its previous life, conversion GEMBALLA was widely covered.
Meanwhile, new features GTS adjustable seats, a panoramic roof and 4WD. Optional are multimedia and the entire cooling box. As you can probably tell from these pictures, this is a kind of cutting SUV as befits quite some way closer to the ground than normal. The rear seats are adjustable and as the front seats, and offer the same level of good sportsmanship, if you look at the flash or movement of the bar of the beast yourself.

New Sport Lamborghini Gallardo by ZR-Auto
Lamborghini Gallardo by ZR-Auto Okay, so we have no idea who ZR-Auto is, but we do have to give them props for the job they have done on this Lamborghini Gallardo. After taking a look at this project we decided that the Canadian tuning firm was a force to be reckoned with, especially since they share a great love for Lamborghini models.
Starting with a regular 2004 Gallardo, the tuner managed to squeeze an impressive 1176 HP to the wheels. How? By adding a Heffner tuned AEM stand-alone ecu and Heffner complete twin turbo engine build. Add that to the Titanium rods, hi-tensile fasteners, sleeved block, pistons, reworked internals, Heffner spec twin ball-bearing turbos with external billet wastegates, blow-off valves, Heffner intake system with cold air conical filter inlets, and a Heffner custom stainless exhaust system, and you have this killer Lamborghini. What makes it even better is that it produces more than 800hp on regular gas!
And the good news doesn’t stop there as ZR-Auto have also offering an IMSA wide body conversion, IMSA custom painted lightweight multi-piece wheels, IMSA 8 piston big brake kit, IMSA clear glass engine decklid, Moton fully adjustable coilovers designed specially for the IMSA Gallardo, a custom color matched interior, and racing restraint harnesses.

Marketing Director of Alfa Romeo UK, Nicholas Bernard, added: “It’s fabulous to know that this supercar has stirred the emotions and unified car fans across the UK. It is the epitome of the Alfa Romeo Sport Cars marque and will provide the design inspiration for future models.”
The 4.7-liter V8 engine in the car masterpiece is obviously a slightly higher performance using a new engine management software. The engine develops 444 hp at its plant stock and Autodelta incarnation promises to 17 more to offer. Technical refinements to the chassis of the car and the suspension was also promised, but no further details were released by the company.
Few details are known at this point, but a remapped ECU should squeeze out a modest 17 horsepower boost from the stock 444-hp, 4.7-liter Ferrari-developed V8. Alfa Romeo Sport Cars Autodelta Alfa Romeo 8C Competizione is also working on fine-tuning the chassis, taking their 8C around some of the finest tracks in Europe to get it just right.

Interior parts aired to attack Company, Inc. Muelheim an der Ruhr in Germany and leather master artificers run and stick a carefully selected by the player skin bridge. Inducts are exclusive designs coated with the single and double crochet patterns are incorporated in reticular approach. The high consistency of performance grip (suitable for driving racing circuit), a smooth and approve all provided. Nissan also says the parts are hand made in Germany to add a little prestige to the hyper-expensive rocket.
The new car will come with the pumped-up engine that will power next year’s Nissan Sport Cars GT-R. The twin-turbocharged 3.8-liter V-6 will unleash 520 bhp at 6400 rpm to all four wheels, while weighing in about 60 lb. less than the current car, thanks to lighter weight parts throughout the body. Peak torque, estimated at 452 lb.-ft., will be reached from 3200 to 5200 rpm. This means the car will be quicker than the current GT-R. The 2012 Nissan Sport Cars GT-R EGOIST will also have a more compliant suspension (via revised spring rates and slightly different geometry at the rear), while still being able to keep up with cars on the track. The interior will also have numerous key “Egoist” touches.
The car will be delivered to customers in December. The price of the GT-R Egoist is set at about 14,000,000 yen or $150,000, roughly $50,000 more than a stock GT-R and about $10,000 less than a Spec V. The company plans to only sell about 10 cars per month. Nissan U.S.A. has offered no comment about the Egoist and maintains that the only GT-R the company will be selling in the U.S in 2011 is the stock one, so don’t expect the Egoist or Spec V to come this way anytime soon.
