Will Green Cars Always Sound Boring?

There's an ever increasing number of green cars on our roads, with a recent surge in available electric vehicles further emphasising this. Electric vehicles are fast becoming a realistic option for urban drivers, offering improved range and useful performance whilst producing zero emissions from their tailpipes. But it would be hard to argue that these cars sound at all sexy, so are future drivers doomed to a near silent future of whining electric motors?

How would you define the word green? Not the colour, but the treehugging, beard growing environmentalist's word. Well according to a reliable source (ehem..Wikipedia), green is defined as something that inflicts "reduced, minimal, or no harm at all upon ecosystems or the environment". So with this in mind, how about defining a 'green car'? You may say something like a car that produces close to zero emissions, something quiet and maybe something slow? You'd probably steer clear of saying something exciting like a 12 cylinder Pagani Zonda or V10 BMW M5, because they scare sheep and spit fire. Green cars sound a bit boring then, don't they? But surely there exist some fun green cars...

Combustion engines aren't very green, especially when they spit fire

To explore this we'd first have to understand what fun is, in the driving sense of course. There are many components to a fun drive, but I'd be confident in saying that in almost all circumstances said fun car will at least make a nice noise. Something like a Porsche Carrera GT would do, or even the screaming VTEC engine of a Honda S2000. In all of my favourite sounding cars, there's a key component that brings a wry smile to my face, it's called the combustion engine.

Well we're all familiar with hybrid vehicles, which utilise both a combustion engine and an electric motor to provide power. They are often referred to as green due to their reduced emissions and improved efficiency, and they also retain an engine so don't lose touch with conventional car characteristics. So hybrids must be examples of potentially fun, and at least slightly green cars. Case closed...

La Ferrari - a hybrid that's not even trying to be green

Unfortunately it's not so simple, as the prosecution has a new piece of evidence against those 'green' hybrids. Take the latest generation of hypercars from Ferrari, McLaren and Porsche for example. Each come fitted with energy recovery systems and hybrid motors, helping to improve performance without increasing emissions. But since each car still requires the ignition of nature's oil in a dozen or so cylinders, they can hardly be called green. And to remove any strands of green that did remain on the Ferrari, the company's Chairman, Luca De Montezemolo admitted that their hybrid motor was fitted purely to boost performance rather than reduce emissions. Not very environmental of them then!

So that brings us back to the definition of green cars. Those that argue only zero emission cars can be called green, may turn our attention to completely electric vehicles. There are quite a few of these on the market at the moment, a popular example of which is the Nissan Leaf. But the Nissan Leaf, well, isn't exactly exciting. Yes it has some clever electric wizardry, but I doubt the lack of emotive sounds will be able to please the caravan burning Top Gear generation.

The electric Lola-Drayson doesn't look so boring, does it?

Nevertheless, there are now electric cars that are built purely to go racing...and racing cars are fun. The electric powered Lola-Drayson B12/69EV currently being developed by entrepreneur Paul Drayson is a great example of a fast electric vehicle. It produces zero emissions yet is still able to reach 200mph, matching the performance of it's combustion engined rivals in the Le Mans 24hours where it'll be competing this year. Plus with the introduction of a new international electric vehicle racing championship called Formula E, we will soon have a fully fledged series of fast electric cars racing wheel to wheel throughout the year.

Great then, we've found our fun green vehicles. Or have we? There's still that one thing that these electric racers can never bring to driving, and that's of course noise. They do make a noise, but it's closer to that of your washing machine then a brutal GT racer. It seems electric cars will always be fighting a losing battle, as combustion engines tend to our primitive needs. Fire, aggression and a feeling of power are all associated with high performance engines, exciting our inner caveman when behind the wheel.

A hydrogen V12? Why not!

So what does the future hold for fun driving? Are we destined to face country sprints with a noise resembling a kitchen appliance to disappoint our ears? Not necessarily. Electric motors are not the only completely green source of power. Hydrogen, a very real option for the future, is constantly being pushed towards becoming a viable solution to providing power in mass produced vehicles. Plus hydrogen requires a combustion engine, meaning we can have our V8s back. Instead of fire though, these V8s would be more likely to spit bubbles thanks to producing nothing more than H2O at the tailpipes. How very green!

Now this being said, we shouldn't discourage the increase of electric cars on sale today, since they are a fantastic solution to urban transport issues. Although, I think it is also fair to say that many of us will be hoping hydrogen will one day be a practical solution, because as much as I'm all for a sustainable future, one without pops and bangs and bouncing rev limits just doesn't sound fun.
