One of Carscoop's alert readers managed to scoop these two photographs of what we believe to be a prototype of the next generation of the BMW 3-Series sedan out testing in Los Angeles.

This is the sixth generation of BMW's hugely popular sports sedan model. Aside from the evolutionary styling changes, the big news for the F30 3-Series is the introduction of a new range of four-cylinder turbocharged gasoline engines with a displacement of 1.6-liter and 2.0-liter delivering between 135HP and 245-horsepower.

Once upon a time, not too long ago, you could count BMW's model series on one hand. For example, in the 1980s you had the 3-Series, the 5-Series, the 6-Series and the 7-Series.

Nowadays, you need both hands and very soon, that is after the launch of the two i-Series models and the rumored introduction of more nameplates into the range, you'll probably lose track even if you asked a friend to lend a helping hand…

One of the newest and perhaps most controversial projects BMW is working on now is the development of a new front-wheel drive hatchback currently known by the acronym F.A.S.T. which stands for Family Activity Sports Tourer.

The engineering teams over at the BMW Group have their hands full these days as they rush to complete testing of a number of future vehicles.

These include but are not limited to, MINI’s Roadster and BMW’s i3 hatch, i8 hybrid sports car, M6 Coupe, the next generation 3-Series sedan and GT liftback, the 7-Series facelift, the four-door 6-Series GT which we showed you earlier today, and case in point, the convertible version of the M6.

As with the 2012 M6 Coupe, BMW is slowly stripping away the disguise from the rag-top model which will feature the same M Division-tuned drivetrain found in the latest M5 sports sedan.

Here are some fresh spy shots of BMW’s new Mercedes CLS and Audi A7 Sportback adversary, the four-door version of the latest 6-Series, which was spotted testing in Europe.

The third iteration of the 6-Series after the two-door Coupe and Convertible models will most likely be called the 6-Series GT or the 6-Series Gran Coupé and will reach showrooms in the first half of 2012. BMW believes the four door model will overshadow the rest of the range and predicts that it will account for around half of all 6-Series sales.

The new, sixth generation of BMW’s 3-Series sedan, codenamed F30 is almost upon us and as a result, we’re seeing more and more prototype models with less camouflage making their appearance on the road or in this case, testing on the Nürburgring circuit in Germany.

Being that the 3-Series has been the backbone of BMW’s success over the years, it doesn’t come to much of a surprise that the F30 remains close to the current model in terms of design.

In 1975, BMW launched the 3-Series as a successor to the 02 series and essentially established the premium compact car segment. The company went on to produce five generation of the 3-Series selling more than 12 million cars worldwide. Even though it changed considerably from one generation to another, the 3-Series kept its core characteristics: a compact body with a classic design, rear-wheel drive, sporty handling characteristics and potent engines.

Launched initially as a two-door coupe, the 3-Series gained throughout the years new body variants such as the sedan, station wagon, coupe, convertible and even a three-door hatchback model (Compact). Scroll down to read a brief history on each generation.

As BMW is getting closer to launching the second generation of the 1-Series, more and more scantily disguised prototypes are being spotted out testing. These latest scoop pictures afford us our clearest view yet of the five-door hatchback version, not only because BMW has reduced the amount of swirly sheeting but also due to the fact that the cars appear to be final prototypes with production headlamps and tail lights.

As you can see, the Bavarian automaker sticks with the tradition of keeping a design for two generations before radically changing the styling. This means the next 1-Series hatchback takes an evolutionary styling step keeping the basic shape of the current model.

Ever wonder why BMW went from the bulky metal or plastic panels to foam and swirly sheeting on its secret prototype models or what goes on during testing of upcoming vehicles at Death Valley, California? Then follow the jump to watch a pair of official BMW videos that provide us an insight into the world of prototypes at the firm’s Research and Innovation Center called ‘Plant Zero’ as well as a clip from the heat testing team.

As it turns out, the BMW M3 sport pickup truck that has been making the internet rounds recently is nothing more than an expensive hoax being prepared by the Bavarian automaker for April Fools’ Day. Nevertheless, we can’t say we’re not interested in a ute that’s based on one of the most coveted sports cars in the market. If you’ve had your fill of spy shots and want to see the M3 sport ute on the move, all you have to do is hit the break and watch the video.

Leading up to the world premiere of the 2012 M5 that’s believed to take place at the Frankfurt Motor Show this fall, BMW is releasing a series of videos slowly uncovering its high-performance sports saloon.

This time, we get a three-and-a-half-long video clip of the M5 flung around on the snow. There’s also a lot of talk going on, but unfortunately, it’s all in German, so if any of you out there can translate the basic bits, we’d appreciate it. We’ll remind you that the new M5 will be motivated by a twin-turbocharged V8 engine with direct-injection pumping out close to 600 horsepower. Take (another) look at the M5 in the video after the jump.

With BMW having already announced to the world the creation of its new ‘i’ sub-brand, through which the Bavarians intend to market a line of stand-alone hybrid, range-extended and full-electric plug-in vehicles, the company is now concentrating on the development of the first cars to wear the i logo.

In this series of spy videos, we see the test driver sub-brand’s halo car, the i8 hybrid sports coupe, which is based on the 2009’s Vision Efficient Dynamics concept model, undergoing cold weather tests in Northern Europe.

Up until now, it was believed that the i8 would keep the concept model’s mechanical hardware with a 163HP 1.5-liter three-cylinder diesel engine located behind the back seats, and two electric motors, one positioned between the diesel engine and the six-speed double clutch transmission, and the other in the front of the vehicle.

After the first couple of somewhat cryptic teaser films, BMW allowed Evo Magazine’s Chris Harris to sit behind the wheel of its upcoming 2012 M5 sports saloon and share the video with the rest of the world.

The Bavarian company is still keeping mum on the performance details, but officials confirmed that the twin-turbocharged V8 lump that replaces the outgoing M5’s 507HP V10 will have more oomph than on the X5 M / X6 M. “Do you really think we would give it less than an X6M?”, BMW officials told Harris. In the X6 M, the twin-turbo V8 kicks out 555HP and 680Nm or 501-lbs/ft of peak torque.
