The W12 engine found in the W12 mid-engined supercar virtually acts in the form of two VR6s combination. This is easily indicated by the 5.6-litre displacement occurring in it. This engine gets constructed through mating the two 15° VR6 at the inclined angle 72°. It is interesting to note that this is the earliest kind of VR engine comprising of 4-valves head. But, this car never got put for production.

W configuration could have been occurred if the VR6 invention did not happen. Audi researched its W-engines for some time period but it finally pulled out from the plug. Some sources said that it did not get success in solving the difficulties arising in exhaust and ventilation.

You should note that it got basically formed with 3 banks involving 4 cylinders in-line. The difficulty was about the way to run exhaust pipe to meet center bank without leading to overheating of the surrounding as well as without wasting very much space.

It appears that the approach of Volkswagen does not get benefited by the experience Audi as the Volkswagen unit finds its basis from the VR6 that was the under development well during the 80’s. Taking advantage from the VR6’s asymmetric designing, the exhaust at the left VR6 runs out from left side, and exhaust at the right VR6 runs out through right side. As a result the exhaust system acts in the same way as in any kind of Vee engine.

The drawback associated with W-engine is that it needs very thin form of connecting rods. This is because of the fact that the crankshaft remains much shorter in comparison with the V-engines. It is interesting to that the VR6 makes use of con-rods having 20 mm thickness and the W-engines perform with the 13 mm ones. This helps to avoid it from getting racing engines. The tight cylinder heads might also restrict its breathing as well as ventilation.

Latest features and creative design, these are few things which every vehicle buyer loves to have. If you have a different car then people will recognize you easily. And everyone want to show people that he have something that can catch your eyes. Today I am going to share one awesome car with great concept…

Arash AF-8

The founder and owner of the car is Mr. Arash Farboud, he revealed the concept car’s design and this AF-8 sports car has been given the go-ahead for full production.

Mr. Bujar Muharremi and Toby Mellor designed the car while they were on work placement with Arash. At the Geneva Motor show in September AF-8 will be introduced with first deliveries arriving in March 2012.
The car will deliver 550bhp with its V8 engine borrowed from a Corvette ZR-1. Price of the car is expected to start at £60k, and Arash say an ‘R’ version with 700bhp is in the pipeline.
