    What is impressive to look at is the time line for developement

    BMW 83 engine timeline from concept to culmination:
    - Concept: November and December 2001
    - Design: January through May 2002
    - Model construction at the BMW foundry in Landshut: March through May 2002
    - Components manufacture: April through July 2002
    - Initial assembly: July 2002
    - First bench test: 31 July 2002
    - Test phase development stage 1: August 2002 through January 2003
    - First deployment in car: 18 September 2002
    - Development to race readiness: October 2002 to mid-February 2003
    In the meantime the test phase for the BMW P84 engine was launched. Following successful bench tests, it was already being tested on the track in its 2004 season specification at Monza on 4 September 2003.

    Shows us how much effort and work goes into development in Formula 1.

    So, powerful engines in F1 something new? What's the point James? Please tell me you're going to throw it in the back of a VW Beatle and attack the vast outlands of your home country, now there's something else...

    Just kidding... I wonder how long before such technology, ( ie: size of gearbox ) makes it into a street car.

    amazing how hot the exhaust pipes get , it's a wonder they don't melt the bodywork during a race.

    They DO melt stuff; a couple of times MS has had to drop out with a carbon-fibre wishbone burnt through - one was at Monaco OTTOMH about three years ago.

    That could be part of the reason for the 'periscope' exhausts, though part of it is also to improve over-car airflow.
