F11 Again or move on to a G31?

Recommended Posts

I have to say, I was all set to do a silly cheap deal on a G31 540i, and in all honesty it didn't excite me all that much. 

 

So definitely go and drive one. 

 

I decided to keep my older car and buy something more fun to sit alongside it. No regrets.

My new neighbour is a car dealer, specialises in performance stuff, and he arrived home last week with a 540i. I met him out walking, and asked him what he was doing to me! Anyhow he described the 540i as disappointing - which somehow made me sad, as it's an aspirational car for me. He didn't like the ride, but that might be down to the specification (20's and non-adaptive). He even has to deal with a cracked alloy.

Anyhow, comfort seats and adaptive damping are still a must for me!

I was in this same position just over a year ago and decided on a late F11 after driving both the petrol F11 535i and the petrol G31 540i. The later car did feel more modern and slightly lighter on its feet, however I hated the dash mounted tablet infotainment, 20" wheels and preferred the more BMW'esque look of the earlier car.

 

A well optioned 6 Cylinder F11 is hard to beat as an allrounder.

Yeah it went fine. I just wanted it to be a bit more exciting than my F11 when pressing on, and it wasn't. 

 

It felt more like another diesel with a nicer sound and a bit more rev range. 

 

It reminded me of my 335i touring, absolutely nothing wrong with it at all, but ultimately a bit run of the mill. I ended up swapping that for an older M3 and an A6 3.2fsi Quattro avant. 

 

I'm actually considering swapping the 530d for an F31 320d auto, as a family car the 320d is a peach. I bought one at the start of the last lockdown as it cropped up locally silly cheap, and so thought I would run it for a few weeks while deciding what to do. It was a 320d ED with cloth seats, and it was superb. 

During summer we went from Norfolk down to Dorset, drove round all week and got home again on a single tank. The economy is just incredible, the car is just as comfy, arguably more so as the seats go lower and the cloth is so much nicer than leather. 
 

I think I am just loosing a bit of interest in these sort of cars, I get more pleasure from 700 miles to a tank than I do trying to make a big family car feel sporty. 

 

Much prefer to run that sort of car a bit older and then spend what I would have spent on buying a new/newer one on something fun. 

 

I guess I thought to 540i was going to feel far sportier, the reality was it didn't, at all. 

it was on a silly £429 down and then £429 a month deal, so really wanted to love it.

Hi. Thanks for sharing. I thought that 540i is not going to be something really impressive,but still would like one or audi a6 3.0 petrol 55tfsi one. 

To be honest i was thinking that 535d f10 is fast car,but it is not that quick or much quicker than my previous e60 530d or audi a6 3.0tdi 272hp. Read online from owners that 535d is a beast and is very fast. Maybe it is after 2.0d. 

Thanks again for sharing. I will try and drive 540i to feel how it performs.

I’ve gone from a 530D F11 to 535D F11 to 540i G31, the 535D was a great improvement over the 530D particularly in terms of power delivery, the 540i is faster than the 535D and feels more sure footed but the lower range and the afterthought sat nav display are downsides. Also I find route selection with ID7 in the G31 rather suspect, often taking me down rather slow small lanes, compared with ID4 NBT in the F11’s which were rock solid  and almost always the same as google, both in route and time. Also noticed that DB map updates for ID 7 are about half the size of those for ID4 which may account for poor route selection in ID7.

Well,cannot comment on multimedia,maps etc. Only had car for short time and in lockdown could go anywhere really to try navigation.

I am keeping an eye out for 540i to appear in my local dealers showroom that i can take out for a testdrive.

They are quite rare in the dealer network - In the end I test drove the 520i as despite waiting months the dealer was unable to find a 540i for me to test drive - they had a couple come in second hand but they were sold before they actually arrived with the dealer.

Maybe there are a few more around than 18 months to a year ago when I was looking for a test drive.

They are rare beasts. I am in no rush though.

Thanks everyone for all your inputs on this. After careful consideration I have decided to buy a G31 520d M Sport and I have found a suitable model that will replace my much loved 525d. That car has been truly fantastic and I am going to miss it very much, as it ferried me and my family in great comfort and safety on multiple trips to France and Italy. I do hope that I won't miss the extra 20bhp that my old steed has, but I favoured in the end a more modern and newer car with less miles on the clock... As I plan to keep the new car for 4 years (like my 525d) time will soon tell if this was the right choice. Once the new car is in my custody, I'll post a few pics...

 

Thanks again all!

I doubt very much if you’ll regret that choice, my last car was a G31 520d and whilst not a race machine it had ample power and acceleration and a pretty good mileage. IMHO the G series is very noticeably quieter and more comfortable than the F series.

I have both F10 and G31 with 20d engine and usually drive them back2back. You are not going to regret as Boba said. Much quiter even with 19 inch wheel compared to 17 inch on the F10. Also, I don't think you are going to notice the difference in engine output rating if you just daily drive the car. To some degree, I think you will even think the G31 20d feels more powerful than F11 25d. The reason being the difference in calibration of two cars. The F10/F11 feels big lazy car whereas the G30/G31 feels more energetic (lighter, fast response). If you objectively measure the parameters, 20d is slower. However, subjectively, you may feel G31 20d is faster.

 

BTW, which year is the G31 you are looking at? Depending on the manufacturer year, even for the 20d, it may have single turbo, twin turbo, or with/without MHT. They all make the car feels different to the driver.

Not ‘twin’ turbo though.

B47TU1 engine for has twin turbo. Two turbos instead of one. can't remember which date it started production though.

Thanks Boba and q96169we its great to get your perspectives. In answer to which version I am getting it a 67 plate (2017) with the B47 140KW (190PS/188HP). My 525d that is being replaced is the N47 160kW (218 HP) which seemed to offer an excellent blend of performance and MPG. I would have loved to get the G31 in 525d spec as that engine produces an impressive 170kW (231PS/228 HP) but they seem to be even rarer than my one. Curb weight on the G31 seems to be much improved at 1,655kg compared to the F11's  1,785kg which I am sure contributes to your driving impressions too.

The G Series feels lighter than the F Series, I went from an F10 520d, test drove a G30 520d and the G30 does feel that bit quicker, so hopefully that'll offset most of the 20 bhp difference. Good choice.

Thanks for the info, I had always thought that the 520d 'twinpower' was a twin scroll.

If it's 2017 car, then it's single turbo version instead of the B47TU1 engine which has two turbos. Both versions are rated at 140KW and 400NM. The added turbo is for better response instead of better output. I logged the data stream from both B47 in my F10 and B47TU1 in my G31. The B47TU1 engine can buildup boost pressure much faster than B47. If I remember correctly, the B47TU1 engine almost always has positive boost pressure even when the engine is idle whereas the B47 has slightly negative boost pressure when idle. Just to clarify: boost pressure = measured intake manifold pressure - ambient pressure

If I remember correctly, B47 is not even twin scroll. The B47TU1 was introduced in late 2018 or early 2019 which then has two turbos. BMW claimed the reason is to meet the RDE requirements.

This is a link I found that covers the B47TU1 engine: https://www.autoevolution.com/news/bmw-b37-bmw-b47-diesel-engines-get-tu1-twin-turbo-upgrade-121785.html

I 100% agree that g30 feels light and quick compared to big and lazy f10. I was actually surprised how nice 520d g30 with mhd performed,even compared to mine 535d f10.  Also on motorway runs its quiter than my f10. 

Also i read that aerodynimcs of the g30 is really good,much improved from f10/11. Cant remember exact numbers,but i think its in region of some super cars. That should make light on fuel.

If remember correctly, drag coefficient is about 0.28 Cd for F10 and 0.23 Cd for G30. Touring version is slightly worse at 0.3 Cd for F11 and 0.25 Cd for G31. Overall, G3x is about 0.05 Cd better than F1x, which is quite a lot. Also, the LCI verison G31 has improved the drag coefficient by about 0.01 Cd (again, if I remember correctly).
