Chinese cars

the ap 550 comment I posted suggests that the gearing is what is limiting it's take of speed , to the merit of over 40+ oomph and economic lower revs at higher speed,
following smart #5 comments, a video I watched suggested geely have either software or similarly hardware/gearing that has the same effect,
which too, is what I thought bmw have suggested will enable neu-klasse to be competitive with CLA on autobahn.

It’s not gearing. It’s literally software controlling the amount of throttle the car systems sends to the motor. It’s limiting throttle until there’s enough grip. It’s not like it’s lost power for the some autobahn efficiency. No one cars about that. Only drive cycle. Also aero is still the key factor as high speeds

gearing is not the reason they are slow to pick up. They still too short geared for the motors and You can see the power bar build as the speed picks up. This is in real life with my eyes but I’m sure you can find a video. Still does a decent 0-60 considering it’s mechanical sympathy approach

this is Offtopic anyway. I mistakenly replied earlier thinking it was EV thread not Chinese.

that higher gearing is reducing torque from the 550 across the early rev range so it's 550nm is little more than the 310 at the wheels,
but the 550 torque extends higher into rev range because it is more powerful
- I'm not sure whats wrong with that logic it's like the honda vtec's no ?

whats take of speed, cos the AP550 allows higher top speed, thats why its geared longer.

we both used the term take off speed - number of torques you can apply at take-off, which contributes to what your 0-60 will be,

the relevance to the thread was discussion of publicized ev torque from chinese video & following posts,

It’s called acceleration, nice singular word, you should try it.

that was comparing shopping cars to V12 multi speed gearbox Touregs, irrelevant.

The gearing isnt impacting anything, its literally the demand on the motor isnt full until a certain speed to provide mechanical sympathy. The whole point of EV is instant torque from zero, they then hold torque until the motor goes asyncronous and then they hold the power (torque will drop as a function of speed). The AP550 does 124mph, the AP310 does 99mph. So its 45% more torque and only 25% longer geared. And it holds the torque longer hence is 240kW not 150kW. You cant just look at peak numbers. The BMW i3 had a later update to limit low down motor output to save the engine mounts.

TLDR: Car only allows full power at 40mph, despite the driver having pedal mashed. Car is traction limited anyway so longer gearing only helps in this situation... the low 0-30 is nothing to do with longer gearing.

I dont understand why you are reading stuff to try and pass it on as info rather than trying to fundamentally understand the subject?

Take off speed is when a plane takes off really, i guess you are trying to say 0-30mph? Ie launch 'take off' acceleration. Take off speed would be 0mph as thats when you start the launch no?

Here i am again. Fallen into the Jpaul trap, try and help, he then completely miss understands disagrees and starts quoting himself as a point of evidence/ arguing with himself, I get frustrated then end up getting in trouble with mods for only trying to help his understanding in the first place.

why do you say 550 gearing doesn't impact the torque at the wheels at zero speed - it effectively means the torque is limited to 25% less than if it had used 310 gearing,
which would have given the car a faster 0-30mph acceleration, say.

I agree there is software on top of the gearing which for other reasons (traction, battery/invertor reliability...) might limit the torque too, at zero

Because the motor isnt being asked for full torque at zero so gearing isnt doing anything negative, if anything its better . 99mph max speed would be silly on that car.

The Born VZ keeps pulling to 90, the normal was dead at 50.
 
Nexperia chip supply problems only going to help UK sales of chinese cars, and push out stellantis/gm/VAG waiting lists

trump has lost control. - Dutch govt took over domestic factory, because of trump tarif risk, but in retaliation, many of the assembled parts come from chinese factory, which is now on short time working

Nexperia's China factory cuts output as Dutch takeover deepens global chip supply tensions

In a sign of worsening disruption to the global semiconductor supply chain, the main Dongguan assembly plant of Nexperia - the China-owned, Netherlands-based chipmaker - has sharply scaled down production in recent days, reducing working hours and idling one third of the machines in one part of...

It's now effecting JLR todays times
Jaguar Land Rover is racing to avoid fresh disruption to its UK car plants in December after China blocked deliveries of automotive computer chips.

With Britain’s biggest carmaker still reeling from the fallout of a major cyberattack, bosses are bracing for the supply chain to grind to a halt next month.

The German engineering giant Bosch, Hong-Kong-based Johnson Electric, and South Korean automotive firm Hanon Systems are among JLR’s so-called tier two suppliers to have said that they will halt deliveries of vital parts.

The firms have triggered force majeure clauses in their supply contracts with “tier one” suppliers — those that directly provide parts to the JLR production lines — because of a lack of computer chips made by Chinese-owned Nexperia, which is based in the Netherlands

I assume the chips themselves are still from tsmc/taiwan even though sub-system done in china, must be some irony that the nvidia chip's trump restored chinese supply of, also come from there,
but chinese haven't invaded yet.
 
Test drove the Chery at a Carwow event last weekend. I wasn’t looking for myself, as it’s not really my kind of car, but I wanted to see if it might suit my parents.

The pricing was honestly quite surprising given how much equipment you get, but the actual driving experience was pretty disappointing. I understand that modern safety systems have to meet a lot of requirements, but they really didn’t feel refined. Other vehicles I tried would gradually ease off the steering feedback, whereas with the Chery it was completely binary, either on or off. Even a slight movement caused the feedback to drop out entirely; it lacked any sense of transition. It was either there or gone, and because you’re constantly fighting against it, you can see how it could cause some odd swerving when it disengages.

You’re still a spectator mate, don’t confuse yourself with anything else other than a pessimistic guy with attitude that’s barely justified beyond you breathing. Weapons grade troll.
 
strange bedfellows
China’s Chery would use a British plant owned by Jaguar Land Rover to manufacture cars, under proposals backed by the UK government and set to be discussed during Prime Minister Keir Starmer’s visit to Beijing next week.

Under the proposal, the Chinese company would use an existing manufacturing facility owned by JLR to build cars in Britain, according to two people familiar with the discussions. The UK has been actively courting Chery to make its vehicles in the country for the last few years, three people close to the talks added.

While deal negotiations are at an early stage and details are yet to be finalised, Chery and JLR will hold exploratory talks during Starmer’s visit to China, the first by a British premier in eight years. The delegation, which includes key business leaders, will arrive a week after the UK approved a Chinese “super embassy” in London, a scheme that had previously attracted criticism in Washington amid heightened geopolitical tensions.

I think we need to be enticing friendly EU manufacturer investment, not an offshore chinese manufacturing base for assembly of parts imported from china,
that may be then taxed going into europe, how many jobs will there be and where will profits go, without R&D investment too.
