Christmas meant consuming more TV advertising than I’m used to. Some of the adverts were good. Others attempted to sell the services of no-win, no-fee lawyers, payday loans, or an operatic car insurance salesman.

It’s easy to love or hate an advert; that’s so often what makes them memorable. The latter, I suspect, is the reason for that opera singer remaining on our screens. 

Oddly, the advert that struck me most was also the one which left with the most mixed feelings: the Audi A5

The story goes thus: weird-looking old car snakes through a wintery wonderland, parks up and turns into an A5. A kind of modern-day, automotive ugly duckling.

My bone of contention is that to my eyes, the ‘ugly’ duckling is nothing of the sort. It appeals directly to my love of engineering and aero-led design. The Auto Union concept ‘duckling’ was penned by Paul Jaray, one of the most significant designers of the era.

He was among the earliest proponents of automotive aerodynamics and streamlining, a look that defined the futuristic look of many cars in the 1920s and 1930s.

He cut his teeth streamlining airships before turning his hand to cars. The Ley T6, Audi K 14.50 and Dixi 6/24hp came in 1923. Jaray’s design raised the Dixi’s top speed from 49 to 62mph purely by fully understanding aerodynamics. Naturally, they never caught on.

Nevertheless, Jaray pushed on. He set up shop in Switzerland licensing his streamlined designs to manufacturers. Tatra used the concept until 1975. Maybach was another car maker to embrace the style and BMW developed a Jaray-penned concept.

But it was Audi with which he is most closely associated. The 1923 Auto Union streamliner concept sadly no longer exists; a faithful replica was built and is the one used in the A5 adverts. Jaray’s influence can also be seen on Auto Union's ‘Silver Arrows’ race cars.

The ’23 streamliner may be many things, but ugly it is not.
