The EV fact thread

[Bobby Dazzler]

Proper cars have oil temperature gauges for the engine at least. I remember many years ago in my old 16v W201s that even after the air vents blow warm air, it takes several miles of driving to get the oil fully up to temperature. And that’s just the engine!

I should think many cars don’t get the transmission up to temperature during the winter on the majority of typical journeys - eg 5-10 miles or something.

And the rest. I’m pretty sure that platform/engine we have in common has a transmission oil temperature, in Winter it can be much more. I’ll try to remember when I’m out in a car with transmission oil gauge.

I’ve noticed that engine oil warms up more quickly when driving at higher speeds - which isn’t ideal in itself - whereas it’s much less pronounced for transmission oil, and I’ve never really hook the time to think about why.

What is this "getting up to temperature" that you speak of?

The reality is total annual vehicle registrations in the UK have never recovered to pre 2020 (pre-covid) levels. Makes your EV market growth claims moot.

So does that mean that it’s a car thing rather than an EV thing?

Not a bad thing, mind.

My response to that question would bring politics into this thread and that is verboten (#buildbackbetter#netzeromadness)

How many electric cars are there in the UK?​

As of the end of October 2024, there are just under 1,300,000 fully electric cars in the UK. This means that around 3.83% of the c.34 million cars on UK roads are fully electric.
The graph below shows the growth in the number of electric cars in the UK between 2020 and 2024. At the end of 2020, there were 205,770 electric cars, which represented 0.6% of all cars on the road and since then the number of electric cars has increased more than five-fold.

"Comparing 2023 with 2022, in the UK, there were:

* 2,535,000 vehicles registered for the first time, an increase of 16% (VEH0150)

* 342,000 vehicles registered for the first time that were zero emission, an increase of 17% (VEH1153a)

* 314,000 cars registered for the first time that were zero emission, an increase of 18%


At the end of December 2023, compared to December 2022, in the UK there were:

* 41.2 million licensed vehicles, an increase of 1% (VEH0101a)

* 1,015,000 licensed zero emission vehicles, an increase of 47% (VEH1103a), including 931,000 zero emission cars, an increase of 48%

* At the end of 2023, zero emission vehicles accounted for 2.5% of all road using vehicles, an increase of 0.8 percentage points from the end of 2022."

Marginal anyway and insignificant at A and B-road speeds. Maybe more significant for EV as they seem to struggle at higher speeds. A wet road has more impact - and that can be at any ambient temp.

Ooo careful now, that's gonna touch a nerve or two, lol

Agreed. Adding to this…

Using a CLS 55 AMG travelling at the often cited 85 MPH average cruising speed as an example - and assuming that all fluids are up to target operating temperature, the road is level and straight, and there is no wind - aerodynamic resistance increases by 10.2% at 0 deg C compared to 25 deg C, whereas the overall running resistance (and therefore power to maintain constant speed) only increases by 5.5%.

Ambient Temperature (C) - Aerodynamic Drag (N) - Running (Resistance N) - Running Resitance Power (kW)
25 - 618 - 1071 40.67
0 - 681 - 1134 - 43.0
-25 - 744 - 1196 - 45.5

Not sure where you're getting these daft examples from
Shortly before I sold the CLS I was on the motorway in a 50 zone and at the end I floored it to get back up to the said quoted cruising speed, just for fun, hear the v8, piss off the tailgating Tesla, etc. The washing machine white blobby Tesla behind me stuck on my tail though. It was a sad - if illuminating - day for people who've grown up talking about carburettors, valves, turbos, cylinders, rear v front drive, V8s, straight 6s, snickety gearboxes, torque converters, twin cams and a dab of oppo. [Expensive performance car and city car] EVs are superior in every way, but they don't seem to be... what's the word: romantic? Are they more like any other digital device: Amazing, capable, but ultimately, soulless?

Pretty much.

Digital watches are amazing and the least expensive will be more accurate than pretty much any mechanical watch at any price point. An Apple Watch can be a perfect watch and do a umogeen things too.

People who are really into watches still buy posh watches, despite being inferior. Everyone else buys a digital, quartz or Apple Watch depending upon budget, functional requirements and desire to impress others.

Cars are no different.
