Has anyone driven an M340i and thought there was something strange about the brakes? I went for a test drive in one and had to brake hard at one point and it felt like the brakes were very weak for about 2/3 of the pedal travel and then suddenly they came on. I have an F generation 430d which doesn't even have M Sport brakes and they feel much better in that car than the M340i. The one I drove did have MHT and this makes me think it may be because of the regen braking?

That’s right, it’s the regen braking. https://youtu.be/9fB6-UOnCLY?t=1178
Weird at first but you quickly get used to it. Something that helps is changing the rev counter for the efficient dynamics display. It had a guage showing when and how much regen is going on. Helps modulate your braking while you’re learning (pre LCi).
Another regen tip - if you easy off the throttle gently - the car coasts; if you come off more robustly - regen braking occurs immediately, this happens even with 1mm of pedal travel.
I'm lucky enough to get a new BMW every 6 months through a work scheme (pay monthly but cheaper than a PCP) had a 340d and changed for a facelifted 340i this week ,
thought the diesel was a stunning car , but the petrol is lighter, brakes better , handles better, faster and it's worth it for the noise alone! .
I would have to be doing significant mileage to go back to the diesel.
Funny thing is my Gf hated the 340d but loves driving the petrol!!

I have also found clicking the downshift when off throttle coasting starts regen too. Save a tap of the breaks to start it off if you want to scrub some speed.

I hadn't realised it had made it to the 340Received my 340d yesterday and I’m absolutely blown away by the performance, handling, interior quality and the efficiency - 50-60mpg on a run. The torque is nuts, a gentle tap of the accelerator is all you need and you’re shoved back into your seat. Anyone on the fence about one, I’d say just go for it!
Quick warning for anyone who's car came with Bridgestone Turanza runflats - don't expect to get more than 10k out of the rears.
Had a puncture yesterday, so took the wheel off to get it repaired and found the entire centre section is down to the wear lines after less than 9k miles, and I don't drive it hard. Even my Giulia Quadrifoglio on Goodyear Supersports didn't wear this quickly.
Apparently it's very common, and isn't due to overinflation either - from what I've read they 'distort' slightly during driving, putting pressure on the mid section.
Have a google, there's plenty of annoyed people out there, including myself.
It's the only car I've had in recent years where I didn't swap the runflats out and sell them on delivery of the car. Probably would've been cheaper.

my car came with them and they are a horrible tyre all around. Will be glad to be rid of them by 10k.

I'd probably go for the Michelin PS4S or even PS4/PS5 if you're not bothered about keeping runflats.I didn't mind them too much, and I'm not a huge fan of Bridgestones. They were far better than the Potenzas I've had on previous cars.
I'm putting Turanzas back on the rear as the car may be going shortly, and I thought as it's only 12 months old it'd be better to have matching tyres all round. Got a good price on them so I'm not too upset.
If I end up keeping it until the end of the 4 year term then I'll stick Michelins on all round when the rears or fronts need changing next, which I assume will be after the summer.
