In the last couple of years, the humble platform has become an unexpected part of many carmakers’ marketing campaigns.
Once only of interest to production engineers and accountants, a car’s underlying architecture has become a star and brand-building opportunity in its own right.
Jaguar’s decision to give the new version of its all-aluminium platform a name (though I’m a bit unsure about its typographical complexity) and to describe it as being key to ‘dramatically expanding Jaguar’s product offering, market potential and customer appeal’ shows how important the iQ[Al] will be to Jaguar’s future image building.
Of course, being able to face down the German premium three when it comes to the use of high-tech materials and construction technology will also be vital for British carmaker, when it attempts to take sales from the 3-series, Audi A4 and Mercedes-Benz C-Class. Why buy an old-tech welded steel BMW when you could buy a baby Jaguar made of aluminium?
In terms of branding architectures, VW led the way a couple of years ago with its MQB platform, which even had its own launch at VW’s Wolfsburg HQ. Mindful of the positive publicity VW managed to extract from MQB, Peugeot-Citroen followed up this year with its EMP2 platform.
iQ[Al], MQB or EMP2, the basic aim of the engineering amounts to the same things: producing a weight-saving architecture (and the accompanying, hugely expensive, production line) that is capable of underpinning as many different types and sizes of vehicle as possible.
Ford can probably be credited with the big breakthrough in common platform technology with the snappily titled EUCD platform. By treating the floor pressing and crash structure as a discrete unit and then having the option of two different-height bulkheads and two different seating heights, it meant that a body production line could create the basis for a low-rise Ford Mondeo or a high-rise Ford S-Max and Ford Galaxy, just by changing a small number of steel pressings.
I once saw an EUCD body construction line in action in Chongqing, China. It was quite amazing to see a floor structure seemingly randomly becoming either a Mondeo or S-Max, as the sides of the body were lifted into place.
