I could be wrong but my read of the differences suggest that the Dynamic is designed to be more suitable for track use. On a track, keeping everything cooler and having more fade-resistant brakes are legitimate issues. For normal driving with occasional episodes of more aggressive, sporty driving, brake fade and engine cooling shouldn't be an issue. I've never had decent pads produce worrisome brake fad on any car I've owned, and most have been sports cars or sporty coupes/sedans. In some cases, heavier-duty and more fade-resistant brake pads can actually perform worse in normal driving because they work best, by design, when they're pretty hot. Casual driving, like on an open highway, may not allow them to get heated up enough to perform optimally. A specific example of this I've seen mention of is the Jaguar F-type with the yellow brake calipers. Those brakes have pads that, in normal driving, don't stop the car as quickly as the lesser red-caliper set. As for cooling, I have had a car or two that had issues but that was in the past and was generally because of a design flaw (as with my three rotary-powered cars that all had trouble circulating coolant to all areas of the engine) . A larger
intercooler or radiator wouldn't have mattered in those cases. I think in general cooling systems seem to have improved over the years and it's been some time since I've had any cooling issues with a car, even when driven fairly aggressively in triple-digit temperatures. But track driving is another matter entirely.
The weight loss that Dynamic offers can be achieved simply by taking out the temporary spare on a Sport model and throwing in a small can of sealant and a compressor. So no biggie there.
That leaves the advanced suspension tuning. I think we'll have to get further reports before we can know what that offers. I'm assuming it's just capable of dialing a stiffer, flatter suspension setup, again as an aid to running on a track. But there might be more to it than that and I guess we'll find out once cars get into people's hands.
If I were planning on occasionally taking the car to the track, I think the Dynamic option would be appealing. But I'm not.
On the other hand, if the dealer had a Dynamic with every quality I desired (color, interior, etc) and I'd have to wait ages before getting a Sport AWD with all those features, I might consider springing for the Dynamic. But I'd probably just wait.
