The 2,660cc inline-four was equipped from the factory with a high-lift camshaft and dual SU H6 carburetors. A reproduction air intake box was installed along with an exhaust header. The distributor is for a standard 100 model, and it was re-clocked and the timing was adjusted in 2023. The oil pan and exhaust hangers were also repaired.

Power is sent to the rear wheels through a four-speed manual transmission with overdrive that can be engaged in both 3rd and 4th gear.

The BMIHT certificate indicates that the car is a factory 100M model built for the North American export market and lists factory equipment and identification numbers.
