Short, wide, and heavy, with very high CG due to upper crankshaft and other engine mass. Short wheelbase and extreme rearward weight bias make it prone to over-rotating on turn-in and under power. Rearward weight bias gives it good traction and good braking. High CG requires lots of roll resistance; weight requires high wheel rates.

GP engine is very peaky, with a very narrow power band, but it is very powerful, which offsets the weight of the car to some extent. The chassis is very draggy, giving an additional disadvantage to the BRM Trainers.

Owen Racing was clearly a two car/two driver team. While the two car aspect is reflected in the original GPL, Stewart and Spence are not.

Owen Racing Organisation worked very closely with Reg Parnell Racing who's main driver was Chris Irwin. Irwin is included in the original GPL.

BRM cars in GPL:

The team began the 1967 season with the BRM P83 powered by their own 3-litre H-16 engine, which had made is debut at Monza in 1966.

Up to the middle of the season, BRM also made use of the BRM P261, a 1966 model powered either by a 2 litre or 2.1 litre V-8. The P83 was supplemented by the P115, based on the P83, but lighter. It had a larger, squarer radiator air intake, and the external coolant pipes were removed.

The P115 was available from Zandvoort, used in practice at Silverstone, but not raced until Nürburgring. It was driven exclusively by Jackie Stewart in 1967. Some sources indicate that the P115 was not used after Mosport, but the table above is based on careful research.

The BRM modelled in GPL physics is the BRM P115.
