Why can't AM design a rear defuser?

[//j17]

The old Vantage had a rear defuser that looked like an after-thought that was bodged together in 5 minutes by someone called Dave, using just a hammer and a few bits of spare 3x2. That's fine though, it was built for one set of regulations and had to be modified as those regulations changed so was never going to look as harmonious as the new 911RSR or Ford GT that were designed to those regulations. What exactly is the excuse for the rear defuser on the NEW Vantage looking just as bodged though?!?!

Most successful GTE in WEC history? Aye, they're doing it wrong.

I agree it's fugly though, but since when were proper race cars designed looks first?

If it works well then its a great diffuser. Looks dont matter.

[Storer]

Looks have nothing to do with aerodynamic efficiency!

[RL17]

Blame the regulations that came in 2016? to allow them to protrude beyond the end of the car.

I guessing it's something to do with the back bumper having to look like the homologated road car leaving a high mounting point for the diffuser to be cable-tied on to.

Simple really, Dave still works there and he’s got loads of 3x2.

Aston Martin has close links to Red Bull Racing.

Adrian Newey works for Red Bull Racing and has a bit of experience when it comes to designing diffusers.

If Adrian Newey had any part in designing the diffuser it probably produces a gazillion points of downforce and the car will romp away with class wins every time it races and there will be a queue of owners wanting replica diffusers for their road and race cars.

I guess the question should really be - If you are more of an expert than they are - why can't you spell diffuser? ;-)

1. I've never claimed to be more of an expert than those at AM, just pointed out that the experts at Ford and Porsche seem to be able to integrate the design (or perhaps more correctly styling) of their rear diffusers in to the over-all design of their cars in a way AM can't. I don't doubt the efficiency of the AM diffuser - but nor do I think either Ford or Porsche would have compromised their designs in order to make them look integrated in to the general car design.

2. An over dependence on auto-correct due to dyslexia.

Have you actually looked properly at the Ford Gt40 and Porsche rear diffusers? It Looks like they ditched the lower half of the bumper to make it work!

Also architecture is totally different ... the Astons not got an engine hanging out back!

Neither do the Ford or Porsche? OK, mid-mounted is further rearward than front-mounted but neither's rear-mounted.

[DoubleD]

Why do you care? The team wont. They only care if it works well.

Mid engine is technically referred to as Rear-Mid-Engine (RMR layout). So yes the Ford and the Porsche are rear mounted.
The Aston is Front Mid engine (FMR layout).
