Another BMW prototype spotted in Spain is the upcoming BMW Z4 Roadster. Slated for a Pebble Beach unveil on August 17th, the Z4 continues its testing trials in high-temperature weather. The Z4 tested on the roads of the south of the Iberian peninsula is equipped with an optional M Sport Package which will clearly bring an extra sporty flair to the roadster.

In this case we find slightly larger tires paired with massive brake discs, an indication of additional power output under the hood. The exhaust tips are located at both ends of the rear bumper under a lower cover that seems to act as a diffuser, instead of the generic bumper we have been able to see so far. In the case of the front bumper the splitter is more evident in the M Sport version, but it is not an element that we have not seen previously in other prototypes.

The successor to the BMW Z4 will be based on the CLAR platform that will underpin all the rear-wheel drive models of the brand, from the new BMW 3 Series to the current 7 Series, this will also be the platform that employs the future Toyota Supra whose development has been carried out in parallel to that of the new Z4. We will therefore find materials such as aluminum, magnesium or carbon fiber in its frame.

The mechanical range will initially be composed by three gasoline versions consisting of two turbocharged 4-cylinder 2.0-liter versions sDrive20i and sDrive30i, and in the sportier version, the M40i we will find a 3.0 liter six-cylinder engine.
