As a relatively compact crossover, you might expect the BMW X3 to be available – in this climate even in the United States – with a four-cylinder engine. But that wasn't the case until now, as BMW has announced the availability of its TwinPower Turbo four to replace the 3.0-liter six-cylinder mill in the X3 xDrive28i.

The N20 engine is the same unit that's already available in the Z4, 528i and new 328i, and joins the X3 along with a raft of upgrades for the 2013 model year. Auto Start Stop, Driving Dynamics Control with ECO Pro, and a power tailgate all join the list of standard equipment, while an optional Driver Assistance Package (with Lane Departure Warning) and an M Sport Package join the options list.

Production of the 2013 BMW X3 xDrive28i with the N20 turbo four is scheduled to begin in April, with prices starting at $37,995 (inclusive of destination), with MSRP on the carry-over X3 xDrive35i pegged at $43,595. Follow the jump for full details.

2013 BMW X3: efficiency, power and technology with new 4-Cylinder TwinPower Turbo engine.

Woodcliff Lake, NJ – February 16, 2012...BMW of North America announced today a continuing evolution of efficiency, power and technology with the introduction of the new TwinPower Turbo 4-cylinder engine (N20) to the X3 xDrive28i. The new engine replaces the outgoing normally aspirated inline 6-cylinder engine (N52) as the next step in BMW's EfficientDynamics strategy. It is scheduled for April 2012 production as a 2013 model with delivery to US BMW Centers in May along with the continuing BMW X3 xDrive35i. Manufacturer's Suggested Retail Prices, including $895 destination and handling, are $37,995 and $43,595 respectively.

In addition, the updated X3 xDrive28i and the X3 xDrive35i now in its second year of production will offer new technology never before offered on the X3 by introducing new combinations of package and equipment options - a new Driver Assistance Package option (ZDA) will include Lane Departure Warning; and the optional M Sport Package will add 19" wheels to the X3 xDrive28i. The X3 also has several upgraded standard equipment enhancements as a recipient of 5, 6 and 7 Series technology. The new standard equipment offerings for both models are Auto Start Stop, and Driving Dynamics Control with ECO PRO and the Power Tailgate. The 2013 X3 xDrive28i also receives 18" wheels, and chrome tailpipes tips previously standard only on the X3 xDrive35i.

The BMW X3 significantly extends its impact on the segment by establishing even newer standards created by its predecessor. The X3 xDrive28i and X3 xDrive35i builds on the success of the original X3 by incorporating new technology, options and packages that were previously only available on BMW 5, 6, and 7 Series cars. More technology, options and packages for both X3 models will now be available providing more agility, efficiency and comfort in the class segment that the X3 started and defined back in 2004.


BMW X3 xDrive28i: new 4-cylinder gasoline engine with TwinPower Turbo technology sets a new benchmark for driving dynamics and efficiency.

With the launch of the N20 engine introduced in the Z4, 528i, the all new 328i, the new TwinPower Turbo 4–cylinder engine is now making its first appearance in the BMW X3 xDrive28i. In keeping with the dynamic overall theme of BMW Sports Activity Vehicles, this new-generation turbocharged engine offers plenty of power, responsive acceleration, torque and low weight for exceptional performance. The new 4-cylinder engine, which provides noticeably livelier power for more driving enjoyment, also comes with lower fuel consumption (preliminary) than its predecessor.

The state-of-the-art, lively 2.0-liter engine marks a return to BMW's roots – it was with lightweight, high-performance 4-cylinder engines in a similar vein that the BMW 3 Series Sports Sedan made its debut back in 1975.

The significant upgrade in power and efficiency is chiefly down to the use of BMW TwinPower Turbo technology, which combines High Precision Direct Fuel Injection, Double-Vanos variable camshaft timing and VALVETRONIC variable valve timing along with twin-scroll turbocharging. On the new-generation 4-cylinder engine, this world-exclusive technology package from BMW again provides a very efficient way to extract more power from the engine, rather than taking the route of a much larger displacement and, in the process, adding to the weight and therefore to fuel consumption. This explains why the more dynamic performance and driving enjoyment does not come at the expense of higher fuel consumption and emissions.

The new BMW TwinPower Turbo 4-cylinder's displacement of 1,997 cc delivers maximum power of 240 hp / (180 kW) at 5,000 rpm while thanks to twin-scroll turbocharging, the maximum torque of 260 lb-ft is developed at just 1,250 rpm and remains constant up to 4,800 rpm. These statistics translate to commensurately dynamic performance: the BMW X3 xDrive28i accelerates from 0 to 60 mph in just 6.5 seconds (preliminary), on its way to an electronically governed top speed of 130 mph. The engine responds instantly when the driver demands more throttle and the vigorous and almost linear power delivery from only slightly above idle continues all the way into the higher rpm range.

BMW TwinPower Turbo technology in the new 4-cylinder engine.
This new engine is the most powerful in a new generation of 4-cylinder engines designed in accordance with the BMW EfficientDynamics strategy, which aims to combine increased driving enjoyment with reduced fuel consumption and emissions. In technical terms, this new 4-cylinder engine is modeled on the current multi-award-winning inline 6-cylinder engine with BMW TwinPower Turbo technology (N55), which is the benchmark in its class for dynamic power delivery and efficiency. This world-exclusive technology combines High Precision Direct Fuel Injection, Double-Vanos variable camshaft timing and VALVETRONIC variable valve timing with twin-scroll turbocharging.

These features give the BMW X3 power not expected from a naturally aspirated engine which would require more cylinders and larger displacement. At the same time, with its all-aluminum crankcase, this engine is lighter and more compact than a 6-cylinder engine of equivalent power. This has obvious benefits for driving dynamics: the reduced load on the front axle gives this BMW SAV greater agility and more improved steering and cornering characteristics.

Twin-scroll turbocharging.
The new 4-cylinder engines feature twin-scroll turbocharging. This means that the exhaust stream from cylinders 1 and 4, and the exhaust stream from cylinders 2 and 3, follow separate spiral-shaped paths to the turbine wheel. This reduces exhaust back-pressure at low engine rpm, allowing the energy of the exhaust gas pulses to be utilized as efficiently as possible. The result is instant throttle response and fast-revving performance that BMW drivers can instantly translate into driving pleasure.

VALVETRONIC, Double-Vanos and High Precision Direct Injection.
The combination of a high power output and a simultaneous reduction in emissions is achieved by VALVETRONIC variable valve timing and Double-Vanos variable camshaft timing. Seamlessly variable control of intake valve lift dispenses with the need for a throttle butterfly. Instead, the air mass is controlled inside the engine, resulting in faster response. At the same time, pumping losses have been reduced to a minimum.

The excellent efficiency is also down to the High Precision Direct Injection system. Centrally positioned between the valves, solenoid injectors precisely control the supply of fuel. The fuel is injected very close to the spark plug, with a maximum injection pressure of 200 bar (2900 psi), resulting in clean and homogeneous combustion. The cooling effect of the directly injected fuel also results in higher compression than on port injection engines, bringing further efficiency improvements.

Exceptional performance assisted by innovative design features.
The exceptional performance of the new engine is also due to various innovative features of the core engine. For example, twin balancer shafts positioned at different heights result in optimized vibration absorption, while a centrifugal pendulum absorber integrated in the dual-mass flywheel conveys a reduction in irregular running at low engine rpm. The driver can therefore make full use of the strong low-end torque without sacrificing smoothness. These factors all help to explain why the new 2.0-liter 4-cylinder engine achieves refinement, noise and vibration of a kind that was previously reserved for BMW 6-cylinder engines.

It is estimated that the BMW X3 xDrive28i will provide much improved fuel economy figures with the new TwinPower Turbo 4-cylinder engine over the former 6-cylinder engine it replaces as it has with other BMW models that have transitioned from 6 to 4 cylinder engines like the Z4, 528i and 328i. With the anticipated fuel economy ratings at the end of the EPA test cycle, the new BMW X3 is projected to be the most fuel efficient gasoline powered BMW SAV sold in the US to date.

BMW X3 xDrive35i: Inline 6-cylinder engine with beefy power delivery, strong torque and superb refinement.
Fans of large 6-cylinder engines have a treat in store too. The inline 6-cylinder engine (N55) in the new BMW X3 xDrive35i will impress performance-minded drivers with its effortless power, exceptionally fast-revving temperament and outstanding refinement. The N55 has been setting standards from the start, as the pioneer of a new generation of engines in which BMW TwinPower Turbo technology with High Precision Direct Injection and VALVETRONIC variable valve timing plus a twin scroll turbo made its debut.

Thanks to intensive fine-tuning of the engine, BMW's engineers have now further reduced the fuel consumption and emissions of the predecessor, while at the same time maintaining its high performance. With a maximum power rating of 300 hp/(225 kW) at 5,800 rpm, the 3.0-liter 6-cylinder unit reflects the sporty personality of the BMW X3 xDrive35i and helps deliver brilliant performance. The high peak torque of 300 lb-ft, on stream between 1,200 and 5,000 rpm, ensures that the power is effortlessly and instantly delivered.

The X3 continues to evolve with new Technology.

Auto Start/Stop will now be standard on both the X3 xDrive28i and X3 xDrive35i. Under certain driving conditions, Auto Start/Stop turns off the engine when the vehicle comes to a stop, providing up to a 3% improvement in fuel economy. Once the driver's foot is removed from the brake or the steering wheel is slightly turned, the engine will re-start automatically. This feature can be switched on/off via a button located next to the Start/Stop button.

Driving Dynamics Control with ECO PRO can be accessed by a button on the center console enabling the driver to select a new "ECO PRO" mode. ECO PRO enhances fuel efficiency by:
- Optimizing drive train, heating, air conditioning and electrical functions by dialing those functions back.
- Displaying driving tips on the iDrive screen to help conserve fuel.
- Displaying fuel saved as "bonus" miles added to the vehicle's normal driving range

New Driver Assistance Package includes Lane Departure Warning that warns the driver if unintentionally straying out of their lane.

All BMW X3s are produced in an expansion of BMW's plant in Spartanburg, South Carolina. Technical specifications and EPA mileage ratings for the 2013 BMW X3 Sport Activity Vehicles will be announced closer to the on-sale date.

      People still thinking that Turbo engines are costly to maintain and break often? Maybe in the 80's. The 90's saw a big transition, look at all the Eclipses/Talons running around on stock turbos at the 100k mark, and Supra's doing roughly the same. I know friends (myself included) with WRX/Evos 2000's that have high mileage and they're fine. Just basic maint that all cars need like belts and such. Funny to see Acura bail out of the turbo-4 crossover, and then see BMW jump right in with one.

      This return to 4 cylinders by most automakers will prove to be 1) costly to the consumer as they will be getting less for the same price as what more cost 'last year', 2) horrible performance vs "normal" engines, 3) consumers taking it again in the pants as these 4 bangers will not be as durable and long lived as their larger cousins, 4) perhaps more fuel efficient, but who cares when you're paying more in repair bills (think about all the 4 cylinder variants of the 80s. Can't wait till the 2020s when automakers cycle back to making real cars with real engines!!!!

        Please explain point 1? The N20 makes more power than the outgoing N/A straight 6. Please explain point 2? Again, see improved power, plus lighter weight. Please explain point 3? Got any numbers to back up that the N20 wont be as durable as the straight 6? Just look at what ford did with its Ecoboost 6 and the tear down in the F150. Point 4 is the same as point 3...and explain why you are comparing reliability in the 80's to nearly 30 years later? Pretty sure all manufacturers have become a LOT more durable (Yes, probably even Chrysler.) Have a good day...TROLL!!

        @SoreCylinder
        Regarding #1 and #2, you need to keep in mind that BMW's turbo charged four cylinder vehicles accelerate quicker than the naturally aspirated versions that they replace. Regarding #3, this remains to be seen. It is true that BMW has had issues with their six cylinder turbocharged engines, but their diesel engines for example (which are all turbocharged) are known to have a very long life. Don't count on automakers going back to "real engines" as you call them. If anything, gasoline engines will continue to be more diesel-like (they've already adopted DI and turbocharging - HCCI may be next). Also, more and more cars will be hybridized as time goes on, meaning automakers will be able to use smaller, more efficient gasoline engines without compromising on power.

        Dude, what the hell are you blabbing about?!?! What's wrong with the immediate torque availability on a turbo engine? Excellent fuel efficiency? And the tuneability of a turbo engine? You need to get yourself out of the stone age and realize that turbo mills are much more reliable then ever before.

      This makes perfect sense. Ask an Audi dealer what kind of relative demand they're seeing for the A5 2.0T vs. the A5 3.2 -- my local dealer says it's like 9 to 1 in favor of the 2.0T. I will miss BMW's NA inline 6s for sure (especially the lovel 255-260HP N52 variant), but they have no choice but to do this given the continued march towards higher fuel economy requirements for all cars. So, no, the N20 wount sound or feel quite as nice as the N52, but remember this is an SUV, not a sports car, so few X3 buyers will notice or care. They will, however, like the fact that it's significantly quicker in every gear and it gets much improved mileage over the outgoing model. Personal biases aside, it's hard to argue against this move based on the market BMW competes in.

      I hear it sounds like sh*t. Should have been able to refine it since they're about the 5th company to build this engine.

      Even well maintained 80s turbo engines went 150-200K if not more (serviced regularly, properly cooled down, etc). Look at the older Saab 900/9000 and Volvo 740/760 turbos. These new modern powerplants should be much more reliable, plus with the added benefit of the efficiency. 36mpg highway in a 5.9 sec to 60 in a 328i is nothing to sneeze at. That's 335d performance and efficiency figures (although without the 425lb ft of torque, but still...).

      This is the first innovative engine(ie game changer) I've seen come out of BMW since the 90s. As long as they don't muck up the maintenance on it by saying stupid things like lifetime transmission fluid and 15k oil changes people will drive these vehicles for a long time. Every since BMW went to the above maintenance plan they become shop queens after 60k and they are the meat and potatoes of many repair shops.

      If you haven't driven the a BMW with the new N20 engine, then you wouldn't know it acutally is stronger than the old six. I have been driving a 335icp w/ the twin turbo for the past 2 years. The N20 328i pulls nearly as hard from 30mph to 60mph in second gear. A vido by eas with confirmed dyno testing stated the N20 factory hp/tq claim is underated. They are now estimating actual hp/tq to be near 260/270. And the thing has a huge improvement with mpg.

      There seems to be a proliferation of 2L Turbo 4 direct injected engines. GM, Ford, BMW, Mercedes, Audi, Hyundai, Kia all have it. It might be the standard engine for this decade, replacing the old 3L/3.5L V6 engine class all together. The BMW engines are great, but the free maintenance program (no oil change until 24,000Km, or all 5 lights went out) will over tax this small engine. Some posts point to the fact that most owners lease their BWM for 3-4 yrs and they don't care about the long term reliability, but the used BMWs with this engine will certainly be worth a lot less with the predictable expensive engine problems.

      Pretty good torque numbers and range for a mass produced engine. Not sure why "soreguy" thinks 4cyl are less reliable. But that is not true. Some of the best 4 cyls ever have great reliability and very low repair. Toyota 22re, honda b/d-series... When you can get the same power out of a smaller engine that is a good thing.

        A 4 cylinder will be less reliable than a comparable straight 6 because of the engine vibrational dynamics, not to mention turbos wear out and need replacement.

          It's not a generalization to anyone who understands vibrations and damping of a 4 cycle engine and why a straight 6/boxer 6, is an ideal design, it's a fact.

          If 4 bangers are inherently sooo much less reliable than straight sixes, it's a good thing nobody tried to make and sell long lasting 4 cylinder engines. Boy, would they have been disappointed after investing all that design effort.

          It is indeed a generalization to anyone that understands what a generalization is and is willing acknowledge one when it is present. Let's go ahead and associate some data with your reliability claims. How much more reliable is the six cylinder than the four cylinder? How soon will the turbos wear out? You seem like you are both very educated and extremely wise, so I am eager to learn from you.

          Do you really want to get into the unbalanced vibrations that are created in an engine by a 4 cycle 4 cylinder timing? 4 cylinders are only able to run without vibrating to death because of large power robbing fly-wheels to damp vibrational instabilities.

        BMW added the lower powered N20 (with 184hp) as an option for the X3 sold in markets outside of North America for the start of the 2012 model year last fall. You may have been thinking of that. Why they have waited for MY2013 (which starts in April) to add the N20 to the 28i is a mystery. But they in fact do just that. With this move, the 128i coupe/convertible and the 328i coupe/convertible are now the only BMW models in the US with the naturally aspirated N52 I6. The only other model with a naturally aspirated engine is the M3. Once all three of these models are EOL'd next year, BMW will have completed the transition to an all-turbo lineup in the US. And there are only a very few non-turbo models left worldwide (and those won't be around much longer either). Who would have predicted that at the beginning of the milenium?
