Just before Christmas I bought an F10 M5. I intended to do a 6 month follow-up post but life got super hectic and I totally forgot - until now. So here it is, a month or two late
Lets start with the car itself - a September 2014 LCI M5 in Monte Carlo Blue with Silverstone Merino leather interior. It was between MCB and Singapore for this car for me and I am still really pleased with my choice. I parked next to a Singapore Grey M5 once and while I still think it is a fantastic colour I still think I made the right choice. I've just taken it past 50k miles, so I've now done a little over 5,000 miles in it. I don't have to drive this car to/from work and I have a Range Rover for shopping trips and hauling things around so that means those 5,000 miles have been driving it because I
want to drive it. I've driven it up and down the country on motorways and I've driven it across the twistiest parts of the North Yorkshire Moors and in all circumstances it has proven itself to be a sublimely capable car. Obviously it is no Lotus Elise in the corners but on actual UK roads it isn't completely embarrassed in the presence of more agile cars either. On more than one occasion I have been able to make significantly more progress than some very special cars indeed owing to how well the M5 is able to soak up bumps in the road without losing its composure (or on some roads, grounding out!).
The engine:
Is it a masterpiece in the same league as the S65 of my old M92 M3 or the S85 in the V10 M5? No, I don't think it is. It is, however, immensely more capable at propelling a car of this sort of mass down the road in ways that sometimes still take me by surprise. Coupled with the magnificent DCT box the drivetrain is always ready to launch you down the road with staggering brutality. Full throttle in 2nd gear is a proper event on a warm dry day, especially for passengers who aren't expecting it
My only criticisms here are that it is a bit on the quiet side from inside the cabin (something they went some way to fixing with this engine in the F90) and that on a cold or wet day the power/torque can and readily will overwhelm the rear wheels. For those who like these sorts of number for performance cars, the MPG returned over my 5,000 miles is a surprisingly high 22.26mpg. Worst tank is 16.1 (47.71L to do 169mi), best tank is 27.61mpg (63.22L to do 384mi). Comparisons to previous V8 cars I have owned look favourably on the M5, with the E92 averaging 20.34 despite it having an "easier" life and it also handily beats the Audi S6 I owned which had a long term average in the late teens. The M2 averaged 27.55mpg over 6,300 miles of relatively similar driving, FWIW.
Drawing comparisons with my previous E92 M3 and LCI M2 I would say that the M5 is faster almost everywhere on the road and leagues more comfortable than either. It isn't as much of an event to drive as the E92 owing to the very special S65 engine in the E92 and razor-sharp steering and it isn't as shouty/doesn't have the same entertaining looks as the M2. On the road, I would say that the M2 has no chance at all of outpacing the M5 on a warm, dry day. They have near-identical 'ring times but on the road your corner speed is limited by how far you can see and not by how fast the car can actually take the corner, so corners are largely a draw unless you're a complete maniac. Punching out of a corner there is simply no comparison, the M5 will just walk away. The straighter the road, the more silly the gap gets. I've not been out for a spirited drive alongside an E92 M3 but I have been out alongside F80s and it is the same story but with a bit less of a difference in a straight line. On track, I have no doubt that the smaller M cars will **** all over the M5 - but that's hardly going to be a surprise now is it
Away from outright performance, you get all of the benefits of the glorious F10 platform. It is a really nice place to be in that traditional utilitarian-but-classy BMW style. Yes the F90 has moved the game on significantly in the interior department, particularly the technology side of things but that doesn't really detract from things for me. I think if this was a commuter car or something I used much more regularly I might be tempted to move to an F90 but that's neither here nor there for me personally.
I've only had two problems with the car since I got it. The first and most worrying is that both rear doors had started to corrode where the window seal sits on the leading edge of the door. Fixed under warranty of course but I wonder if there is more corrosion in store down the road for these cars. The second issue was a puncture after just 3000 miles on these tyres but which revealed that the valve caps have all started to corrode into the valve stems. I had this happen on my 535d as well and it is caused by the fitting of incorrect valve caps. I am having this corrected but I'm having to wait for the correct TPMS valves.
I wanted a single car that I could take out on the UK roads and get enjoyment from whenever I wanted but also be able to get in it and drive for thousands of miles across Europe and this is exactly what my experience has been in the F10 M5. I love it as much 7/8 months in as I did on the day I collected it and I am looking forward to doing many thousands of miles in the months/years ahead
