Am I not correct in thinking Audi were really the first to pursue the benefits of aerodynamics.![]()
In the sense, that the Audi 100, (200 and 5000) was the first major production car to do items such as flush windows and the like. Meaning a 136 hp engine was enough to do almost 200 km/h when a w123 with the same power would struggle to top 180. You are correct, but the history of aerodynamic car design dates much longer back.
HowStuffWorks "History of Aerodynamic Car Design"
Everycar even 50 years ago had a certain amount of thought towards how it would crave through the air but what I mean was Audi seem to be the first to hunt out those final few areas to improve to the level we are at today.

Didn't realise the Merc was this low too, it appear that the 0.25-0.26 is the limit at the moment because I can't recall anything better than that for a production saloon.
BMW F10
Aerodynamic efficiency has also taken a backward step. The outgoing car not only had a smaller frontal area but also a lower drag coefficient down to 0.27. The new car starts from 0.28 in the modest models, rising to 0.29 in 535i and 0.30 in 550i. This is a night and day difference from the latest Mercedes E-class, whose drag coefficient ranges from 0.26 to 0.28. Ridiculously, BMW has already applied an innovative automatic flaps to its nose intake, which draws the right amount of air to the radiator depending on cooling demand , thus keep aerodynamic drag to the minimum. It's probably time to head hunt the aerodynamicists from Stuttgart.
Seems like the Beemer engineers needs a lecture from Stuttgart, K-A

One thing I have always admired from Audi's is the very tight/thin shutlines or door and panel gaps![]()
Yeah, the W212 was a Saloon record when it was released. And the E-Coupe is like a .23-.24, which was (and I think still is) a production car worlds-best?
I guess .26-.28 range is where it's capping right now.
The Honda Insight is 0.21, if I recall correctly.
I'd take the E though...![]()
As mentioned earlier, unit sales will be a most substantial measure of the success of these automobiles. BMWs' F10 5 series is set to become the most commercially successful 5 series BMW ever. In its' German home market, almost 5300 F10s' were sold in January (as compared to almost 3700 W212 E-Class M-Bs' and 2400 C6 A6s'). It was Germanys' 5th best selling car in January, following the VW Golf, VW Passat, VW Polo and Opel Astra).
One can see that the introduction of the F10 Touring has initiated a massive boost in 5-series sales. And the long-in-tooth C6 A6 continues to sell in relatively good numbers. A6 sales will increase very substantially when the new C7 model hits Audi showrooms. According to press reports, order flow for the C7 is absolutely overwhelming and Audi is becoming very concerned about its' capacity to deliver cars on a timely basis. And the Avant hasn't even been introduced yet. The novelty of the W212 M-B appears to be waning a bit. Perhaps one factor is the slow but inevitable demise of the classic sedan as the vehicle of choice for taxi fleets. It appears to me that more and more taxis are VW Tourans, M-B B-Class' and Skoda Octavia wagons.
It indeed is the best in the class. To these eyes, both A6 and F10 interior look one class above the E.
Thanks Jimmy. Where do you get your German sales figures. JESMB used to have them years ago, but sadly not anymore. Has the 5 traditionally outsold the E in Germany?
I wonder how they're carving up global market share.
In the U.S, I don't think this A6 will dethrone either the E or 5 just yet, but in Germany, China, and ROW in general, it looks like the A6 could take the sales crown quite quickly.
Was that for the original Insight with the covered in rear wheels or is that for the latest model?
