We have added photos from the latest spotting of the BMW M4 Coupe (F82), together with a short clip from testing on the Nurburgring track.

Have a look at the latest F33 4 Series convertible prototype, revealing more of its defining characteristic - its metal folding roof. Earlier spyshots (reposted below) show the hard top operation and the design is largely similar to the current E93 convertible.

The F33 will share the same engine and transmission options as the F32 coupe, as well as the coupe’s general styling. So, imagine the coupe that you’ve seen revealed, but with this metal folding top.

Production of the 4 Series convertible (both 435i and 428i) begins later this year - in November 2013.

The F10 M5 LCI model with Competition Package shows off its new power, exhaust, and handling at the Nurburgring.

Official details have not yet been released, but the M5 Competition Package is said to be introducing the following upgrades:

• HP increase (approximately 15hp)
• Top speed increase
• M Carbon Ceramic Brakes
• Sport suspension
• Sport exhaust with black tips
• Enhanced steering
• 20″ competition wheels

We’ve given you live action looks of the M235i and 228i during winter testing, now have a look at the M235i coupe undergoing testing at the Nurburgring this week.

The M235i mule is seen in Estoril Blue II and shares its wheels, M Sport brakes, and double black exhaust pipes with the M135i hatchback. A trunk spoiler lip can also be seen clearly.

M235i and 228i coupe production begins in November. There will be no 235i model in the US or elsewhere, as the M235i will take its place in the lineup. The M235i will feature the same powerplant and mechanicals as the highly touted M135i hatchback [reviews].

We’ve also reposted below the first interior photos of the M235i, as well as some up-close photos of the exterior.

We have posted countless spy photos and videos of the upcoming BMW i8 hybrid sports car, but we’ve yet to spy it on an actual track… until now. BMW trotted this i8 mule out to the Nurburgring this week and we managed to capture it on the Nurburgring for the first time.

The i8 is expected to boast 354hp / 500Nm torque, 0-62 mph in approximately 4.6 seconds, top speed of 155mph, 78 MPG (european test cycle), up to 47 MPG average fuel consumption, with just 66kg/km emissions, all from its 1.5L three cylinder turbocharged petrol engine (in rear) with a 128hp electric motor (in front).

The i8 will hit the market next year and is expected to come in well above $100,000.

It’s been a busy test week for BMW at the Nurburgring, which includes some more testing on the F32 435i M Sport. Not much is revealed in these photos, but they provide more looks at how the 4 Series (F32) looks in motion.

This is a 435i M Sport in Estoril Blue II. The M Sport bumpers remain under camouflage. The headlights feature the optional full LED headlights with squared-off corona rings.

The M Sport brakes are fitted, but the M Sport wheels are not. See the wheels 4 Series lineup (from the 4 Series order guide) posted below for what the M Sport wheels will look like (as well as on the blue 4 Series spotted at the airport reposted below).

We give you the first clear look at the interior of the F22 BMW 2 Series (M235i) coupe. As the 2 Series lineup is based off the current F20/F21 1 Series hatchbacks, it comes as no surprise that the interiors are nearly identical.

Interior

As this is the M235i (there will be no regular 235i), we see all the M Sport bits fitted from the M135i hatchback, including alcantara sports seats (with hexagonal pattern and blue contrast stitching), aluminum dash trim and door handles with hexagon texture, and estoril blue accent strips on the dash. The door panel shares the same hexagon pattern as the seats. Also seen is the 6 speed manual transmission.

But, the M235i does feature something the M135i does not - the M Sport … CONTINUED

We have spied a new F10 M5 LCI mule and it showcases some new design elements. Seen for the first time on the M5 are double slatted kidney grilles (a la the M6). Like the M6, the F10 M5 LCI will also feature an M5 badge on the grilles, which is covered under black tape but can be seen on this mule’s grilles.

This M5 wears new style wheels, in black, which look great set off against the gold M carbon ceramic brakes. Also seen are the optional LED headlights with squared off corona rings.

The rest of the exterior look to only receive very minor updates, with the biggest change coming to the area on the front fascia under camouflage tape. That change can be seen … CONTINUED

Will we be seeing the F32 4 Series coupe make its public debut at the 2013 Shanghai auto show in just over a week?

These photos are purported to be production stage 4 Series coupes at the airport waiting to be loaded for a plane to Shanghai. They may look like they are wearing the usual pre-production prototype camouflage, but per insider Scott26, the camouflage is just protective vinyl for the trip.

Although the production 4 Series coupe has recently been spotted completely revealed [pics below], we have not yet seen the M Sport version (which is represented by the Estoril Blue 4 Series seen below).

The 2013 Shanghai auto show begins on April 20th. Keep your fingers crossed
