BMW gave us a real treat in the Arctic north today! Sure sure, this is another set of pictures of the F20 1-Series hatch, but look closely, there is something new and different here. BMW had previously removed almost all the masking tape from the hood to give us an advance snapshot of the styling language we should expect to see on the next generation 1-Series and 3-Series. However, before the cars were a bland silver color which hid the true depth to the styling. Now with a sparkling red color, we can see the depth in the lines of the hood.

From the first look, this is the most sculpted hood ever seen on a 1-Series (not hard with only 1 Generation), or even a 3-Series … CONTINUED

As part of BMWs press release on the new X1 xDrive28i was included information on an all new TwinPower Turbo 4-cylinder engine, which Im sure we will be seeing more of across the entire BMW lineup. This engine seems to be strongly based on the 6-cylinder counterpart and we can expect to see it come in a variety of displacements.

Tonight, BMW dropped a bit of a bombshell, very discreetly and buried within a press release about a new edition to the BMW X1 family. BMW has as of now officially launched the new BMW X1 xDrive28i.

The xDrive28i is the familiar X1 we already know and love but now has under its hood a brand new 2.0L gas powered 4-Cylinder engine which uses BMWs TwinPower turbo technology, good for 245HP and 350Nm of torque. You can read all about this bombshell of a new engine in our separate post here.

For now, check out all the photos of the new X1 xDrive28i below.

It’s been nearly 4 months since the all new 2013 M6 convertible was spotted, but it’s appeared yet again, and in the most unlikely time and place possible – Northern Sweden in the dead of winter. Now that the 6-series convertible has been officially debuted, BMW has moved onto the development of the top of the line 6-series cabrio.

The M6 prototype now sports the production M6 bumper underneath heavy front camouflage. Other signature M features already seen are the quad exhausts and huge front brakes. The wheels seen here are winter wheels/tires for testing purposes only.

The F12/F13 M6 will share the same engine as the upcoming F10 M5 – the turbocharged 8 cylinder motor from the X5 and X6 M (the BMW S63 engine, a 4.4L … CONTINUED

German AMS has published an interesting article comparing the BMW 525d sedan with the Jaguar XF 3.0 V6 D.

Unlike the name suggests, the 525d is powered by BMW’s N57 3.0l inline-6 Diesel engine, yet with a lower output of 204hp and 450 NM (530d: 258hp). It’s quite popular in Europe because it’s the entry level inline-6 Diesel. The car tested was matched with the optional 8-speed automatic.

Just like the name suggests, the Jaguar XF 3.0 V6 D is powered by a 275ph 3.0l V6 Diesel engine. The test car was equipped with a six-speed automatic which AMS considers a good match despite lacking the refinement of BMW’s automatic.

The verdicts:

The BMW 525d scored 530 points (out of 650) and wins this comparison. The … CONTINUED

The guys over @ Motor Trend have put up this mega 11 page comparison between the large sedan offerings from all the usual suspects in the large luxury sedan game. But they didn’t just make this a booring old comparison, they threw in all the non-traditional offerings that are available from automakers you wouldn’t have expected 10, 5 or even 1 year ago.

Why all these large luxury sedans in this economic climate anyways? Despite the bad economy, almost every automaker has refreshed their luxo offerings and have pushed the bar foreward even more, blurring the lines between cars meant to be driven by yourself and those meant to be driven by a chauffeur. This isn’t all that surprising– before the big economic collapse, every automotive … CONTINUED
