The trend over the past decade or so, especially with luxury brands, has been to replace traditional car model names with a mix of letters and numbers (called alphanumerics). Cadillac, for example, went from names likes Seville, Deville, and Catera to STS, DTS, and CTS for their car lineup. BMW has long used a number for the model (3 series, 5 series, 7 series, etc) and the engine displacement (2.8L, 3.5L, 5.0L, etc) to create their 325, 535, and 750 models. Mazda went even simpler in the 2000's, dropping their previous numbers and names (Like 323 Precidia and 626 Cronos) for a single number to denote the class or size of car (Mazda 3, Mazda 5, Mazda 6), with CX used to denote their SUVs (CX5, CX7. CX9).
While some of this might seem a bit random or even lazy, apparently brands have studied the subject of naming their vehicles and found that it has a significant bearing on how people consider them. Acura famously ditched their names (which most car fans will say were pretty impressive) like Legend, Vigor, and Integra, for model letters, like RL, TL, and IL. This was because they discovered that customers would say "I drive a Legend", not "I drive an Acura". In creating a strong brand, companies want consumers to think of the brand name, not just the model name, so it's not surprising that more and more automotive brands are going the alphanumeric route.
Let's just hope that they manage to be a little more creative than the Chinese brands that have adopted rather unwieldy and forgettable names like this DN6460-III. After I took this photo, I saw two similarly-named vans on my walk home:
Hmmm, that actually DOES have a nice ring to it. I'll see if I can throw together a demo tape, you're all invited to my first concert...
