Most noticeable is the mega-sized maw at the front. There's a bit of white-painted mesh to break up the front grille, but it's still clear that the opening has expanded all the way down to the front spoiler. That spoiler has been changed as well, featuring points on each side instead of one big arch.
Moving around to the side, the slender vent that extends from the wheel arch on the standard DB11 has been exchanged for something larger. It's shaped very differently as well, looking a bit like a shark's tooth or a Star Fleet badge from Star Trek. At the back is another significant change. The rear bumper now features a clearly functional diffuser for improved aerodynamics. Vents appear around the exhaust tips, too. However, the ducktail spoiler appears unchanged, as does the rest of the rear.
There are a couple of interesting details inside as well. This prototype is fitted with Recaro race seats, which are pretty neat, but will likely be replaced with cushier, leather-wrapped seats developed by Aston. Just behind the seats is something even more fascinating. This DB11S has a roll cage. It's hard to say if this is just a one-off for the prototype, or if it will make it to production. Certainly other companies, such as Porsche, have offered roll cages in production cars. But in the case of Porsche, they've only been included on the most hardcore sports cars. However, we're not sure this Aston is the same type of track-focused car that Porsche's caged examples are.
As a bonus, we also have more photos of the upcoming DB11 Volante, due spring of next year. It's still sporting the '80s-grade shoulder pads to hide its haunches, but the rest of the car is pretty well exposed. Naturally, the little air scoop behind the rear quarter windows was lost with the switch to a soft top, but we expect everything under the fake steel panels will be very similar to the coupe, just like the rest of the car.
