No Engine, No Brand Identity? Electric Cars And Branding

Let us run a few engines past you. A warbling flat six. A growling V8. The howl of an inline four changing cam profiles. The smooth buzz of a rotary. How about some names now? Hemi. Vortec. Powerstroke. VTEC. Renesis. Ecoboost.

Noticing a pattern? The first list is clearly engine layouts, and the second are trademarked brand names for particular motors. The similarity amongst them all is that you could probably link every single layout and name with a particular car company, or sometimes even with a particular model. Rotaries for example have been synonymous with Mazda for many years now, and Renesis is their brand name for the engine in the recently discontinued RX-8 sports coupe.

Engines and brand identity

Brand identity is an important aspect of any car maker, but as you can see from the examples above, it runs particularly strongly down to the engine powering the vehicles. Nobody would mistake a Hemi for anything but a V8 made by Chrysler, for instance, and the engine even defines particular models, marking them out as something special. What would you call the electric motor in a Tesla Roadster though? Does it even have a name?

And if the motor does have a name, how do you then define it against the electric motor in any other EV? Its application aside, does the motor in a Tesla hold any more brand identity than the one in a Reva G-Wiz does?

Car companies trade heavily on the image, and indeed the characteristics and sounds of the engines they drop into their vehicles. When you take this image away from electric cars, whose powertrains effectively have no distinguishing features beyond their abilities to move you at a different pace from the next EV, what takes their place?

Identity in EV drivetrains?

Some might say the battery packs will come to define the car. Apart from the very obvious defining feature of range and the mixed press range figures can attract, battery packs can actually vary significantly between EVs. Tesla, BMW, GM and Ford all rely on liquid cooling for their packs, reasoning it to be better in a wider variety of driving conditions.

Nissan have gone a different route though with their air-cooled pack, a move that Tesla CEO Elon Musk has criticized. Apart from anything, Nissan state cost and simplicity as a major reason for going down the air-cooled route - not dissimilar to the cost and simplicity reasons for using air-cooling on motorcycle engines. Perhaps for a while we'll see a divide in the cooling method manufacturers choose.

Some manufacturers choose to use different charge usage too - A LEAF will use 90 percent of its battery pack, a Chevy Volt only 50 percent. Mentioning the Volt too, it's hard not to see how the drivetrain itself isn't a defining feature, some EVs being full battery-electric and others using range extending engines - though of course, the debate still rages whether those deserve to be called electric cars...

As for motors themselves, there is already little to define them beyond the power they output and different types of whine they emit - and comparing the whine of electric motors is like comparing the sound of dozens of generic four-cylinder gasoline engines - there isn't enough of a difference to make one more special than another.

At the advent of EVs requiring sounds to warn pedestrians of a vehicle's presence, there's always the option for manufacturers to create their own distinctive sound to mark out a model or a brand.

Finding pastures new

With a lack of brand identity in an EV's drivetrain then, manufacturers will surely have to look to other areas in which to distinguish their vehicle.

The obvious one, of course, is styling. In the automotive world styling carries more identity even than engines. A kidney grille is unique to BMW, and it's an aspect that will no doubt be carried over to the upcoming MegaCity EV, with their "hoffmeister kink" rear window line surely set to make an appearance too. The car is undoubtably going to carry unique styling though, marking it out as something a little special.

Renault are treading the same path, with their proud involvement in EV development. Whilst their Kangoo Z.E. and Fluence Z.E. models will be similar to the existing gasoline and diesel production cars, they've promised distinctive styling for the Zoe Z.E, and the Twizy tandem city car previewed at the Paris Auto Show has crazy styling, unmistakably unique, and unlike anything with a regular internal combustion engine.

It's another possible route for automakers. Some EVs will look fairly similar to regular cars, a trick the 2011 Nissan LEAF pulls off well, looking distinctive yet inoffensive at the same time, not differing too much to regular cars that it'll put off more conservative buyers.

Other makers will be able to make best use of electric vehicles' unique powertrains and the different packaging requirements of motors and batteries to create cars that would be utterly impossible to build as gas or diesel models.
