BMW M635 CSi review. With its M-Power engine, was this 158mph Coupe peak BMW in the eighties?

The BMW M635 CSi was powered by the same M-Power straight six used in the BMW M1 and M5, giving it a top speed of 158mph. It was also a highly successful race car, winning several 24hr endurance races between 1983 and 1986 but what's it like to drive today…

I love this car Harry. I used to work at a BMW dealership in the 80's and sold this actual car when new to the original owner....I was very tempted to bid on it at the auction as I don't think you will find a cleaner example...in (imo) the best colour for the shape. The personal connection made it even more tempting. I was very surprised that it didn't sell at Silverstone Auctions as it is a super example AND an earlier chrome bumper car which is purer in shape than the later (though plusher) big bumper cars. These days it is popular for everyone to criticise the TRX tyres for poor grip....I can tell you that the grip from these tyres was faultless...I have covered thousands of miles across Europe in E24's with TRX tyres and they were never found wanting. The bigger (non metric) wheels fitted to many now are easier to source, and probably cheaper, but they don't look correct and can spoil the ride if too low profile. This is a grand tourer...not a car for hustling around country lanes ( a E30 325i of the era is more suited for that task) I am racking my memory bank about the close ratio box...I am not sure it was very 'close ratio'. The C/R gearboxes on BMW's of that era were dogleg boxes and high revving at speed.

[@1983dmd]

I agree...not close ratio at all !!!

[@jackdoe3889]

It was standard ratio as in direct 4th and 0.81 5th. 3.73 final drive with 25% LSD. The dogleg gearbox was the Getrag 265/5 Sport, standard in M3 E30 (except US).

I found the TRXs on my e28 dreadful in the wet, but very good in the dry and surprisingly good in the snow. Completely outdated tech tho and have been for a long time. I switched to 17” Alpina reps - too big - then went down to 15” BBS cross spokes with 205 section tyres. These were ideal, though 16s might have looked and handled better. The 390mm TRXs are somewhere in between. The e28 M5s had 16” BBS which were perfect in my opinion.

The M635CSi was never raced by BMW though. They did race the M30 (12valve) 635CSi but for 1986 it was replaced by the E30 M3. The M1 engine had Kugelfischer mechanical injection, not the Motronic used by these and the M5. TRX's were acceptable on the M5 and M635CSi but not very good on lesser cars - lift-off oversteer in the wet could be scary. The old 528i E28 really did need a set of P7's. Those wheels aren't two piece but one piece BBS 415 style 5's with the black line - they arrived in 1986/7 with the E32 7 Series. A 1985 M635CSi would have had either the 'real' BBS metric split rims with the ring of bolts (recalled because of air leaks) or the one piece sculpted TRX-1 wheels, 165TR390. From an era when BMW's were genuinely prestigious and desirable. * sigh *

[@douglasjames4905]

Excellent review of one of the legacy BMW milestones. Why can I say that? I had the 3.5L manual 635Csi that had been ordered and built for a German doctor. Built by Alpina, they then spent three days on the 'ring dialing it in. When it was 2 years 'old' the good doctor traded it. I purchased it imported to the states. A full Alpina prepped Henna Red beast it was. Dogleg 1st gear, everything else much as the M6. Sunroof delete, 60 in 2nd so up- shift didn't degrade competitive acceleration to 60mph. The car was purchased by a Seattle stock-broker without him ever testing it! Directional stability at 135mph+ was astonishing; Harry did not test this in it element! Six-series and B roads...don't do that, likewise as a go-to-the-shops, no. Sold it on when my '67 AM DB6 Vantage came over the horizon. Oddly, it didn't compare to the best I can of, say 40 vehicles....that Alpina 635 was hands-down the finest continent crossing device man could envision. I built a 1-series M-spec [nat asp!] that beyond doubled the cost of the bugger, just to get it right. Runs circles around a 635, yes, but it's spirit echoes from Alpina 635. That's what to find, gentlemen....

[@grndiesel]

I have a bone stock CSi, so I can't hold a candle to what you describe. But I do agree about directional stability at higher speeds. I can't claim 135+ obviously, but did touch triple digits a couple times and noticed how everything tightens up, the faster you go. I road tripped the car across mountains and freeways for nearly 2000 miles once and it never missed a beat.

This has taken me back. In the early 80s heading out of Calais in my old Triumph I have a clear memory of big BMWs flashing past on the way South with the driver's toe down and the car's tail squatting with massive negative camber . I would take the M5 over this too. The M5 is just right from every angle whereas this is not quite. I do not think the front spoiler fits with the rest of the car and lesser models look all the better without it. Interestingly, the M5 unlike its lesser sister the M535i), managed to do without any skirts or front spoilers so I guess it would be possible. I had a M535i in the Caribbean in the 90s. This was a hybrid model that had the M5 suspension set up and steering but the regular 3.5 litre engine which was quite enough for a postage stamp island) That sensibly had the lower geared dog-leg box which was an option on the M635i and added another element of 'specialness'. I see this car came from Hairpin. I do wonder why they almost never quote the asking price of their stock. That is one thing that potential customers really dislike. A garaghe should not be embarrassed to disclose what it wants to charge....

[@manfredschmalbach9023]

The spoiler is exactly that: spoiling. The 6 series BMWs are best bone stock. I also prefer the steelies with a dog dish over the BBS or Ronal wheels. Had a couple when these were just slightly difficult used cars. As I had two 3.0 CSi and a CSL each of which I today regret having sold ....

[@Beer_Dad1975]

To my eye the 635 looks very 80's (even if it does date back to the 70's) - whereas the M5 definitely looks like it was designed in the 70's with the boxier, simpler lines - as to what is better, that's subjective I guess.

POA should be illegal !

[@ursrudin9964]

The M5 was orderable with or without M Technic at that time. The first models didn‘t have it, I think about 1985 to 1986 it was orderable. With the E24 the early ones only had the M Technic frontspoiler and the wider „plastic wheel arches“. Later on from the year 1985-1986 the M Technic kit was orderable (sideskirts, rearspoiler, rearbumper) giving the E24 a very decent sporty look.

These shims are located below the camshafts.

@@1983dmd - mine needed ALL the shims replaced when I bought it and for piece of mind. After that, you are correct....some not all need replacing.

Absolute dream car for me! Great video Harry, thank you

[@alexmartinez280]

Thank you Soooooo much Harry!!!!! BMW M for life!!!!!!

[@carza355]

Interesting this engine was put in the E23 7 series in South Africa, where it could also be matched with an auto gearbox.

[@monk3yboy69]

Yes, the beautiful 745i What a car.

[@jamespink4202]

Ahhh. When BMW employed talented designers... My favourite BMW shape. I had a '67 E9 2000 CS for years, the first with the famous Hofmeister kink in the bottom line of the rear side windows. Peak BMW in my opinion. Wonderful!

[@jasonblair4057]

Awesome one of my favourite cars of all time. This time I saw one on the road as kid I could not stop smiling. Still puts a smile on my face today. Thanks for the great video.

[@farturinn]

Thanks for that Harry, quality material as always

[@SabretoothBarnacle]

Sreten would like one of these.

5:25 Not many engines post-emissions controls worth taking a look at and this is incredible. I liked my '95 Supra but you needed a bit more imagination to figure out how it worked. I'm sad to see most cars nowadays have a plastic engine cover instead of letting you see anything.

[@JamesGadbury]

Under the ghastly plastic engine cover, nothing spectacular awaits

[@broti]

one of my most favorite 80s car! thank you for showing it!

[@S_Edward_Burns_ArtsEditor]

Proper BMW to experience; mid-80s was the highpoint to me. Thx so much as ever. Carry on!

[@stroopwafel6141]

Prettier than a lot of new BMW's.

[@oliveroshea5765]

prettier than all new BMWs. And Mercedes, Audis etc etc

[@coolquitepowerful]

They don't do like it no more

[@ssb8344]

Harry’s by far the best car KZbinr there is. I wish I had that collection and huge garage like his.

[@area51isreal71]

Absolutely stunning appearance and gorgeous looking dashboard. BMW were really on top of their game with that stunner.

[@mmmmmmmmmmmmmmm420]

I'm in my late fifties. My abiding memory of 6 series of this era was premature rust. They went really scabby when they were relatively young.

[@gaycha6589]

When BMWs were cool looking

[@johntamlyn6383]

Lovely styling. As you say with a big glass area and delightfully slim pillars. Clear simple controls, no confusing and distracting touchscreens!

[@michaelbarlow3686]

Thanks Harry for another great production on an Icon

[@weets69]

That is a sweet BMW. Always luv the looks of these. Can’t touch them even now if you could find one sorted. Great vid yet again Harry

[@ATomRileyA]

Great video, always good to see some cool older cars.

[@MB-uw6eh]

Another favourite. I’ve had 4 BMW’s and my current is the X5. I love the shark nose and bull nose eras of the BM’s. Classic model. Enjoyed revisiting it.

[@JazzSaxUT]

Fun video Harry! I used to own a 1984 633csi. Loved that car.

[@ashleyweston5420]

Great to see such an icon so original and in such good nick. I lusted after a 635CSI for years and when I went to buy one (not an 'M') was so disappointed, the interior wasn't a patch on my V12 XJS and as a family car nowhere near as practical as the hugely underrated SD1 Vitesse with similar performance. You mention touring cars success in the 80's but these cars didn't have it all their own way, the SD1's were all over them like a rash. Great car and video, thanks for showing.

[@lampat.8830]

What a video !!! the sound of the car the camera angle most importantly the way how he present this car to us It's more like a story teller Epic content !!

[@garygrenda632]

Enjoyed the review mate. I'm one of the fortunate owners of the early chrome bumper version of the m635csi, albeit a converted LHD to RHD one. I agree with the GT nature of the car, but a change to modern rubber, and some adjustment built into the suspension geometry has turned it into somewhat of a corner carver, but still retaining the compliant ride characteristics . Unfortunately the factory gearbox has expired but I've replaced it with the very close ratio dogleg 5 spd gearbox from the E30 M3, which really enhances the driving experience , but as the gearbox is not overdrive, it needed the taller 3.23:1 diff (from the original 3.73:1) to keep the revs on the highway reasonable. Keep the reviews of these old cars coming, everyone is great to watch.

[@alanduncan3337]

Love this car, I had posters of it on my wall as a child. It looks far more exotic than many of the so called sports cars of the day. Great video Harry.

[@davidbillberg2203]

Sounds great!! Thanks Harry!

[@jasongriffiths6522]

loved this Harry

[@TouringCar.]

You always know by the smile on Harry’s face just how much he enjoys the car. Can’t wait for the next road trip Harry!

[@geoffjordan1254]

One of my all time favourite cars. Thanks so much for the video. An M635i would really be the perfect garage partner to my E28 M353i

[@NigelMarston]

One of my absolute favourite cars ever. I never found myself in the right place at the right time to buy one but I'd love one for a weekend toy.

[@jameshewitt8828]

Absolutely beautiful, love M Cars and Porsches, especially classic old school ones of each

[@Vogall]

What a glorious sound Harry. What a car.

[@scottjohnson4319]

This car is gorgeous with a cleanliness and delicacy never to be seen again. Personally I could care less if it's as fast as it looks, it's a joy even standing still.

[@starfish370]

This is the the BMW I would like to own. Fabulous styling and well presented. Definitely a dream motor car! Thank you for the video, Harry! 👌👌👌💯%✔️
