Automatic cars – does anyone sell one of these in the UK?
Here you go.
Obviously you’ll need to get an orange 5 too.Posted 4 years agogeoffjSubscriber
A friends mum had a green one branded as a DAF, in the late 70s or early 80sPosted 4 years ago
We’ve just come back from the USA and whilst there we did 2100 miles in the hire car, a Nissan Altima, which isn’t for sale in the UK.
Now, obviously, it had an auto box and for a start I thought nothing of it (I like autos) other than noticing how smooooooth it was. Then as I drove more I started trying to see if I could count how many gears it had. Nope. Can’t tell. It was utterly, totally seamless on acceleration, literally no sign of it changing gear at all. Only if you put your foot down did the revs climb and gear changes became noticeable. Seriously impressive.
So I googled the car. Ahhh. That explains it. It wasn’t a conventional auto but a CVT!
Now I’ve only seen CVTs on small cars before but this was some seriously impressive box. Under mild and steady acceleration the revs stayed low and constant giving seamless drive. As soon as you back off the revs dropped to just over tickover and cruising at 80mph was a tad under 2000rpm.
Being a real geek, of course I checked the fuel consumption whilst we had it. That never dropped below 35 (UK) mpg which was during some spirited driving up lots of miles of Rocky Mountains and twice topped 40mpg.
I’m assuming the “gear changes” I could feel when I booted it were electronically selected ratios to give the impression of gears, as such a thing is available on some auto motorbikes.
Now this is a 2.5l 4 cyl petrol engine with 183bhp tugging a pretty big car about (I’d say it was bigger than a Mondeo)
So it was doing pretty much what our 1.6 manual Focus does, fuel wise. I can live with that!
But does anyone make a CAR (not MPV or 4×4) with this box or similar in the UK?Posted 4 years ago
Nissan sell CVTs in the UK on Micras, Notes, Jukes and Qashqais
Yep. But one is too small, one is a box driven by old people (And still to small) one is a 4×4 (stylee, and therefore useless) and one is the second most ugly car in current production (after them fat Minis)Posted 4 years ago
Wouldn’t a Vauxhall Ampera do essentially the same thing, engine at constant RPM, no gear changes in the transmission. Except rather than a gearbox doing the clever stuff there is a battery and some motors?
Yep. Probably. As would a Priuis. Already been there.Posted 4 years ago
But you cant tow a trailer leagally with a Prius in the UK. No type approval see?
Also, are there any used ones around?tor5Subscriber
hmmm, think the Ampera is a bit different, because the engine never actually drives the wheels – it is simply used to provide juice for the motors, a bit like a diesel loco. It’s apparently quite nifty because the engine can be tuned for maximum efficiency at a set RPM, rather than having to perform reasonably across a range.
No idea about towing though, or used examples

This is my understanding, based in part on something I saw on topgear, therefore likely to be bollocks
Audi multitronic/m-tronic is a CVT, available on A4, A6 and no doubt other VAG models. I used to have an A4 estate with a 2.4 petrol engine and the CVT; that transmission was a brilliant piece of engineering and I don’t understand why it’s not more popular. At the time the 2.4 was the largest engine they did with the CVT but I see from their web site they now do a 3L diesel so I guess they’re confident that it will take a shedload of torque.
Have also hired an Altima with the CVT in the US; the VAG implementation is better IMHO.Posted 4 years agotonyg2003Subscriber
I had a Merc A class rental car with a cvt a few years ago. Got to be the future. What’s the point in having defined gears between your highest and lowest ratios?
The Merc A class CVT is known to have lots of issues.
I guess the “always in the right ratio” of CVT is becoming less of an advantage as we head now to 9 speed autosPosted 4 years ago
