The McLaren MP4/8B
Converting my working drawing of the MP4/8 V8 Ford-engined car to the MP4/8B V12 Lamborghini-engined car.. This is the 'engineering' drawing I do before copying it to the watercolour paper. Note all the changes occur behind the monocoque with a 124mm increase in wheelbase and stretched topbody to cover the longer engine.
It was great to see the McLaren MP4/8B (Chrysler) Lamborghini V12 car at Goodwood last weekend. The car was never raced but intended as a 'device' to keep Ayrton at McLaren for '94 and also have as an alternative engine option in case the future deal with Peugeot didn't materialise.
Under chief designer Neil Oatley, I was the project leader for this car during the summer of '93. The monocoque was a modified MP4/8A, with revised engine mounts. The longer (than the Ford V8) V12 engine required 'stretching' the car by about 4.875" (123mm). This was done by creating a longer floor, topbody and airbox.
We didn't really have any great expectations for the car as it was only a test 'mule'. However, when Ayrton drove it at an Estoril test, he thought it was amazing and phoned Ron Dennis to say he wanted to race it at the last few races!. That was never going to be possible of course due to contract reasons and, not least, the fuel tank wasn't big enough for the car to reach the end of a race.. This didn't deter Ayrton however, who said he would happily run out of fuel if he could compete at the front of the grid again.
Perhaps I should add this car to my Car_Profile_Art 'to do' list? Who would buy a print? Let me know in the comments.. It would be very plain in white but it is an historically interesting car.
