[quote=howard}...So what we see might be a modern version of the early Porsche Turbo issues - sudden surge of power as it comes on boost??[/quote]
Howard. There is not a sudden surge of power as it comes on boost... early Porsche Turbo's were huge and took a while to 'spin-up'... hence the 'sudden surge of power' that you refer to! But from my drive in December, I recall that it's a very linear power and torque delivery, very predictable. This BMW engine has had huge amounts of R&D behind it to make it feel almost normally aspirated in it's power delivery. However it's a lot of power/torque to put though a light rear end with no traction control, especially on wet roads. A good driver will learn how to respect and master this quickly... but it's not something an inexperienced driver could jump straight into and then firewall the right boot!
