Are we being forced to go electric?

[Dadam]

As has been mentioned multiple times on this thread, switching to electric is not a panacea. We still need to reduce our overall energy usage, however it’s generated. The emphasis on efficiency will therefore remain and even rise. Aero will be a huge consideration. I’d expect to see minimum drag coefficients per type of vehicle. So boxy designs may well be consigned to history.

RIP Volvo 940!!! ⚰️⚰️

Did I imagine all those glossy ads about wind tunnels and drag coefficient?

I'm guessing the ads weren't about a Rav4 or a landrover?

Yaaaaawn.

Do you ever get bored of repeating the same old rubbish?

But making EV’s creates a bigger “carbon footprint” than an ICE vehicle. Having children creates a giant carbon footprint. EV’s are not the silver bullet.

My ice is only one litre with a turbo strapped to it. Low emissions, it’s not like these SUV’s. I can sleep easy knowing I haven’t got an EV that kids helped make mining crap in sandles for 1 pence a 12 hour shift. Then the large EV will have to be recycled somehow in 10 years.

You do realise that those kids mining crap in sandles are supplying the fuel industry with cobalt to remove sulphur from the refining process.

A 1 litre turbo engine won't last very long, unless babied along, highly stressed design to get performance

I'll come back to you in ten years, unless I cannot find you or forget

It's around 16k miles to offset the C02 build extras. But there is the not so small benefit of zero tailpipe emissions. Which is a huge benefit for suburban/town/cities.

Model 3 has drag coefficient of 0.23. This being one of lowest figures of any modern vehicle

The people currently living in the parts of Europe that are on fire may beg to differ..

Very true and coming our way soon. Sadly.

People are fitting new battery packs in the early hybrids, they are a long way over ten years. Now seen as classic cars !

The emissions are elsewhere, but they are still there. Whatever fuel you use.

With a bit more effort they could make a good looking car out of it, like these.

BMW 5 series has a figure of 0.22, as does the Merc cla!

There's less emissions. Some people run their EV entirely on solar.

A petrol car is always going to be 100% polluting.

But the Government can wipe them out rather than having to rely on individual users.

Same drag coefficient as a Toyota Supra or Lambo Murcielago; not too shabby

or a landrover?

Suggest you do some reading. It's a bit weird to mention a 70+ yr old agricultural offroad vehicle in any discussion about car aerodynamics

Simple fact of the matter is that on the road, air resistance is overwhelmingly the force that limits your speed and range, so there has always been a strong focus to improve the aerodynamics. This has resulted in the drag coefficient of a typical car gradually reducing over the decades.

The Lightspeed 0 launched last year with a drag coefficient of 0.175, but seems to have stopped production within a couple of months. I think that leaves VW with the drag coefficient crown.

Before that was Tesla:

BMW and Audi do pretty well. When I was younger is was the Opal/Vauxhall Calibra.

Before them, lots more.
