Hi Guys,  I had a wee citroen 2CV....What a wonderful bit of design that was....You did however need a fully functioning brain to drive it

Brains are so yesterday, now you just need a massive wallet.

One of the first cars to advertise central locking - you could reach both doors from the drivers seat!

My younger brother used to get himself, his son and their tandem in his 2CV - not sure how but I think it involved removing seats.  Citroen have always been innovative. I knew someone with (I think) an Ami6 which had a flywheel which stored energy on descents to use later.  You could hear it spinning after he parked.

Bring back the pre selector gearbox and a centrifugal clutch, then if you can't work that your licence is withdrawn! Or you have to drive a Daf 600

 

With the switch on the dashboard that you only ever switch once!

Variomatic transmission

[edit]

The 600 was the first production car, after the 1920s Clyno, to have a continuously variable transmission (CVT) system - the innovative DAF Variomatic.[3] The DAF Variomatic employs engine speed, via centrifugal weights, to shift the transmission and is enhanced by an engine manifold vacuum. It is the only car ever produced which went faster by the simple expedient of gently and gradually releasing the accelerator once top speed had been reached – this increased manifold vacuum which helped the variable pulleys shift to an even higher ratio so even though the engine speed stays the same, the transmission increases the car's speed, in the case of the DAF 600, from 60 miles per hour (97 km/h) to nearly 70 mph (110 km/h) given enough time and level road.

The Variomatic also permitted increased engine braking by operating a switch on the dashboard which reversed the action of the vacuum on the pulley's diaphragm, seeking a lower ratio with increased manifold vacuum.

👍I had a Riley Falcon in my youth with pre select gearbox and centrifugal clutch. Great old car. If the selector lever wasnt exactly in the correct position the clutch pedal would, when you raised it come right up and over . Only did that once,  very embarrasing as you had to come to a complete stop and start again .

It also stalled once at a  "T" junction and I had to use the starting handle (remember those) as starter motor  was defunct . I didnt realise that the hand throttle was also above idle and as soon as it starred it came forward pushing me slowly across the road ! Luckily i managed to get out of the way and into the car to stop it. Fortunately in those days roads were far less busy . My girl friend just sat in the passenger seat in total hysterics 🤣.  Imagine nowadays no young girl would even be seen dead in a 1930's classic.

Different world , different values.... often lower.

Yes, they are great - needed even more thanks to the 'brighter than the sun' LEDs that permanently dazzle me........

There maybe hope ahead, having just invested in some yellow overglasses myself!

I've got a modern equivalent of this, a CVT 4wd vehicle. It works well. Only downside is the gearbox oil is horrendously expensive.

Had to get rid of my beloved Audi A6 3.0 TDi Quattro three months or so ago because at 18 years old it developed a warning light which would have been far too expensive to sort out.

Had three Volvos in the past, 164 3l straight 6 auto, 2.3 245 Estate and a 2.1l 240 auto saloon. All pretty simple and reliable but the 2.1 would not get better than 20mpg. The V90 estate was the car with the longest load length that I could find and got hold of a very nice example which even has a Tempra spare wheel!

With all the so called mod cons and driver aids it is very complex to get my head round the touch screen which is not advisable to play with whilst driving.

I found that I could disable the stop/start (for one of the three driving modes) quite easily but it only lasts for one engine start. Operating the Satnav whilst driving is a definite no no and even changing the heater settings on the move is dodgy. Why do they have to make things so difficult now? Volvo should take lessons from Audi regarding driver controls.

  Volvo is currently owned by the Zhejiang Geely Holding Group, a company which owns over 15 other vehicle makers. Even with the wide array of brands that they own, the Zhejiang Geely Holding Group pays close attention to the unique aspects of each vehicle, continually working to make them better for drivers worldwide.

Perhaps they are not interested on the small UK market?

I’ve just ( well 5 months ago) been given a brand new crane lorry for work. DAF, 32t gross, 420hp and auto box. I hate it🤢🤮.

I suppose it is ok for only doing long motorway work but multiple deliveries OMG it’s useless. The full auto mode  keeps trying to change up all the time, even nearly full 1/2 way up a hill. They’ve taken all the low end power and torque from the engine by giving it a more acceptable eco rating. Luckily there is an “eco off” mode and a manual mode.

BTW my old MAN 360 ( manual box, long stroke engine- excellent torque) did 14mpg…..this new eco lorry - 7mpg. I told my boss I didn’t want a new vehicle!

Maybe it has the gearbox out of the A team's van, that is always changing gear.
