Virtual trial and error

Interesting article, Beth. That's a nice way to increase possibilities in design -- to do it with computers instead of physical prototypes. While the process may not have saved design time in this case, I would imagine it would inevitably save time as this practice becomes part of the standard design process.

Good point, Rob. As CAD and CAE become more of an integrated process as opposed to siloed tools done by different groups within engineering, there are bound to be design efficiencies. The real benefit, here, though was upping the number of prototype designs explored without upping the number of physical prototypes having to be built. Time saver and money saver.

Another interesting thing about this car is its looks. Apparently the company really wanted its vehicle to stand out. It looks like it came from another era, heck, another planet. With so many recent American cars looking alike, the Donkervoort is refreshing.

High value, low volume

To me, this is almost a case of CAD meets kit car. This is a high performance, high cost, low volume automobile. Its design and manufacture would probably be economically unviable without the time/cost/knowledge/ leverage provided by an advanced CAD/CAE program, where you can in effect do virtual design, testing, and prototyping.

Chuck, while we didn't talk specifically about surface modeling work done on the D8 GTO, you just have to look at it and see it's an obvious candidate for that kind of software. 

Rob, to address your points about looks. The whole design challenge with this car was to make it more "muscley" and higher performance, but also take weight out of the car even when adding some more safety functionality in the door frames. While achieving those goals, the team had to keep the car looking like its heritage which is definitely something that heralds from another time and place. Likely not a design for the masses, but for the wealthy driving enthusiasts that are the target audience.

The tightly integrated design team has a lot of advantages.  I'm sure saving on the number of prototypes saved money.

I'm more of a muscle car guy, but I'd try this open wheeler...when I win the lottery.

Always fun to analyze carmaker claims from the comfort of an armchair.  This one has many that raise one's eyebrows.   400 HP at  5400 rpm with no turbo from 2480cc  -  Really?   0 - 100 k/h in 3 seconds with RWD only?   Less than 1500 lbs?   Of course I don't read Dutch so I could have missed the magic ingredient.

But I love those numbers, it's what I'd love to drive.   Now, about those looks....

That's funny, Bill. I like its cartoonish look. Very over-the-top, a modern version of a 1940s roadster. Looks like it weights a ton, but apparently it doesn't.

Carbon fiber really gets around

Interesting that carbon fiber was used in the chassis. This wunderkind material is really getting around, whether in composites or on its own.
