Each time I look through the cars and builds that have rolled through our #FeatureThis program, I am more and more amazed. It’s a true global pool of amazing machinery, and after looking at the submissions I always end up with a huge smile on my face. Cars like this 1969 Opel Commodore are very much a reason for that smile.
The project belongs to Heikki Mattila of Finland, and I have to say this is one of the most interesting builds I’ve seen in a while. Considering the high level of the submissions we get, that’s saying quite a bit.
When you hear “Commodore” you might think of the popular Holden model in Australia, but the distantly related Opel Commodore A actually precedes the Aussie version by over a decade.
Heikki got the car with the idea of running it in a local road race series called “Roadsport”.
The regulations for the this class are very loose, so Heikki got to work tearing down and completely rebuilding the Commodore from the ground up. As of now, he already has four years invested in the build.
In order to shave weight, improve aerodynamics, and give the car an aggressive look he ended up dramatically redoing the Commodore’s body work.
Here you can see the handmade front fenders and the beginnings of the front spoiler, all constructed from fiberglass.
Besides the fenders, he also built the hood, trunk lid, doors, and rear panel himself. He also added polycarbonate windows.
To power the car, Heikki swapped in a BMW M20B25 inline six with a dry sump system, Autoverdi rods, a Shcrick cam, and a set of custom-built individual throttle bodies.
The motor is estimated to produce about 230 horsepower. It may not sound like a lot, but it should more than sufficient considering the car only weighs 850 kilograms, or 1,874 lbs.
At the same time, the chassis was also completely re-designed with an end product that looks more DTM than ’69 Opel.
The front suspension features spindles from a Honda S2000 and tubular wishbones that Heikki built himself. He also added a complete steering rack from a Ford Escort Mk.1 that was widened by 26 centimeters.
The rear end is from a Mazda RX-7, with a 4.88 final ratio.
A 1969 Opel Commodore might not be considered an exotic or pricey car, but it’s clear that there was little expense spared in this build. There is Ohlins suspension at each corner.
Along with equally impressive Alcon brakes.
The interior is likewise totally race-ready. Roll cage, pedals, digital cluster, OMP steering wheel – it’s all there.
The transmission is a Getrag from an E30 M3 with a dog ring modification.
Needless to say, Heikki has made some incredible progress with this build. Four years may be a long time, but there’s no doubting it will be worth it once the car is complete.
Perhaps it will make an appearance alongside other equally mental machines at Gatebil?

Thanks for sharing, Heikki!
