Before McLaren was a huge operation based in England and a technological partner with the likes of Mercedes and Porsche, it was a racing car company founded and run by two blokes from New Zealand. Together they built some damn fine racing cars.

The Can-Am cars built and raced by Bruce McLaren and Denny Hulme were so dominant people took to calling the no-limits racing series “The Bruce & Denny Show.” Only combined might of Mark Donohue and Roger Penske with full support from Porsche could unseat the two Kiwis and their mighty McLaren M1C.

Forty years later the M1C remains an amazing car, and now a German outfit is making spot-on replicas and selling them to people like us.

Can-Am (formally known as the Canadian-American Challenge Cup) was big in the late 1960s. It was an anything-goes environment with little in the way of technical regulations or rules. Two seats, enclosed wheels and basic safety equipment were pretty much the only requirements. It wasn’t unusual to see cars with huge wings, sucker motors, semi-automatic gearboxes and even titanium frames. The most unbelievable technology was thrown at the age-old question of “How can we make it go faster,” and the results were amazing.

McLaren was the first, and most dominant, team in Can-Am. The cars were always Kiwi orange — the national racing color of New Zealand — and usually powered by Chevrolet V8 engines (though some had Ford or even Oldsmobile mills). They started with the venerable small block but later pushed big-block engines to power and torque levels so extreme that even the seemingly fearless Hulme was once heard to say of the McLaren M8, “Maybe we got too much.”

The M1C was the last of the McLaren tube-frame cars before the team moved on to monocoques. It had a small-block engine outfitted with four 48 IDA carburetors. It cranked out 500 horsepower — an ungodly amount for a 355 cubic-inch engine in the late 60s. The engine was a stressed stressed member of the chassis. Out of the box the M1C offered jaw-dropping performance thanks to its overall weight of just under 600 kilos. McLaren built 25 M1Cs in 1966 and ‘67 and sold them as the McLaren Elva Mark III.

And now, an outfit in Germany called LMP Engineering is recreating this sweet car to highlight its knowledge of 3D-CAD hybrid modeling software, CAD/CAM production technologies, 3D-Tube laser cutting, 3D-machining, surface scanning. They’ve built one already and will produce others “for interested fans of the Can-Am racing series.”

The LMP replica is a stunning work of art, the kind of car you enjoy looking at as much as driving. We’ll take one. In Kiwi orange, of course.

Uh....did they get the memo that this car was created without all that fancy business? Seems kind of odd to say it that way. That's kind of like saying I replicated a three hole punch pattern in the side of a sheet of paper with a laser to highlight my knowledge of laser hole punching, computerized measurement devices, and paper modeling skills.

Here's a link and pic of the already sold prototype. It appears a bit more than an accurate scale model.

I don't care how they designed and built the thing, if I had a gigantic pile of dough I'd buy one.

Uh...did you see the term "surface scanning", among others? They were pointing out that they scanned the surface to get an accurate shape.

It wouldn't do for me to have money. I'd so buy one of those.

Turns out that a complete race car is slightly more complex then 3 holes in a flat piece of paper...

The original wasn't designed with all that stuff, but then who needs an 3d scanner to design an original? And had that stuff been around when the original was made, it likely would have been used... Why would you draw the car out on paper when you can do it cheaper, more accurately, and faster in cad.

You also seem to have missed the point that the entire idea behind the project was a showcase of these new technologies. It doesn't make much sense to showcase "knowledge of 3D-CAD hybrid modeling software, CAD/CAM production technologies, 3D-Tube laser cutting, 3D-machining, surface scanning." with out actually using any of them.

The 3D laser tube cutting machine is simply amazing. Any tube sizes, any joint angles, any offsets, any combination of tubes; the computer figures out the dimensions and cuts the tube 'fishmouth' and length to within a few thousandths. And each cut takes 2-3 seconds. Certainly would save time on labor, and materials to have every one of the tubes cut exactly before you start. There's a demo video out there somewhere.

If CAD/CAM, 3D-Tube laser cutting, 3D machining and surface scanning can replicate a McLaren M1 with modern build qualities, what's the problem?

Other than I cannot afford it?

With this technology available, I may have to start buying lottery tickets so I can commision a replication for the McLaren M6B.

And I bet the production tolerance variation among the original 25 cars was far greater that it will be for however many copies they make today.

I'd buy one. And I'd have them use that fancy CAD software to make it left-hand drive.

You would or you will? As mentioned above, they are for sale. You guys sure are getting offended at the thought that all this fancy technology that is making the replicas available still keeps it costing several times more than a bunch of dudes in Thailand pumping out hand made replicas. Sure, it's probably higher quality and more consistent, I'll give you that.

If you want to impress me with some fancy new technology, copying race cars isn't the best way about it. Might be flashy, but copying a racecar is actually fairly simple in the world of making digital versions of parts that already exist. Make a copy of a destroyed piston or a mangled wheel....THAT is tough to model and replicate.

There isn't much I wouldn't do for one of those.
