- Well, the result is pretty clear. But try to watch how capable and competitive the 630 Ci actually is. Of course - thanks to it's manual gearbox :-). Very interesting...

That 645 on start feels sluggish and almost feels like it lacks power . I have owned 630i and currently own 645ci . I can tell that 630i is a fast car no doubt and masterpiece of 3.0 naturally aspirated engine , but 645 is different ball game . This video doesn’t do justice to 645ci as in reality it is noticeably quicker car . 630 is quick in city , but on highway it doesn’t feel that fast on the other hand highway is where 645ci shines , instant torque and acceleration pretty much at any speeds . Plus the sound is music to the ears .
Hi how big different accelerate 630i and 645ci. And is a big different of consumption. I think now about 645ci 635d and 630i but interesting off your opinion to this two.
Hi, I'm planning to buy myself a 645. Are you satified with it? Do you have to spend unnecessarily much money on servicing?
@@benedektoth3905 these engines can be problematic , so my advice is be careful when choosing the right car as if it wasn’t well looked after it can quickly turn from dream car to nightmare . If they are correctly maintained they are great engines , a real powerhouse and gives a lot of joy to own and drive .
@@arturforever2060 There is definitely noticeable difference in acceleration in comparison to 630i to 645ci no doubt , all thought 630i is weary impressive on acceleration from 0-100km/h . The difference is weary noticeable between these two on motorway speeds after 100km/h where 645ci would take the lead . Consumption is definitely better on 630i . 645ci can give some good fuel consumption if driven carefully especially on motorway although I found it extremely hard to manage giving its power and temptation to utilise it 😁
@@piccadillycircus9416 thank you for answer.
I have driven both. A 2005 630i with N52B30 and my own 2004 645ci with N62B44. Both with the ZF6 auto.
The 630i really is a fast car, but you have to use the revs. Unlike the N52, the N62 has the power from down low and makes it a great all rounder for that, but the extra 500rpm makes the 630i sound more like a sports car. If a 630i pulls earlier in a race, you will need suprisingly alot of road to catch it. With muffler delete, it gives you that M3 vibes haha! Alot of car for the money!
The places where the 645ci performance shines is with warm tires. I managed 0-100kph in 5.5sec with on extra passenger and 60% full tank. It also keep pulling alot stronger after 180kmh. To keep the engine happy and alot more reliable, just change thermostat to a colder 90°c one. The OEM 105°c thermostat kills these engines in the long run. For sound, muffler delete makes this car sound alot like the Mercedes-Benz 6.2 AMG engines. That angry muscle car roar!
In the end of the day, both cars will make good daily drivers.
I drove 645ci smg with special exhaust. You are able to hear that beast around 6 km away and its psycho. I fell in love with this one, the sound of V8 is just magnificent.
Agree to you, 630i is an underestimated car although its a beast
@@The_TURK. Google ECS tuning 90c n62😉👍
Very good explanation. I had an 645ci with a valve exhaust, it sounded insanly good and is ideal to cruise as it has more torque in the mid and low range :)
Mine was also always running temperatures between 105 an even 120°C on fast highway passages, but was it wasnt an issue so far.
Now i am having a 650i with standard exhaust, just need to get the crazy valve one back ;)
@@danielgregorius8843 Why would that be an issue anyway? Those are perfectly normal engine oil temps.
nice vid, i was driving around a 640 gran coupe not too long ago, i loved it
Thank You very much. We also! 640 Gran Coupe is also recorder on our channel :)
hello good job . not huge difference between the 2 the 645 flu at the start ?
Acceleration assistant with SMG
The acceleration assistant enables optimized
vehicle acceleration at racing car level on road
surfaces with good adhesion when starting off.
Do not use the acceleration assistant too
often, as otherwise components will wear
prematurely.<
1. Activate the Dynamic Driving Control.
2. Press the DTC button for
longer than three seconds.
3. Press the accelerator pedal down fully:
Kick-down. The ideal starting-off engine
speed is set.
To maintain driving stability, do not deactivate
DSC if at all possible.
Thank you for you comment! Interesting
I have driven 645ci, it dousnt feel that fast but it is, it is because it's a very heavy car
Yes, it feels powerful, not fast. Agree
The 6 series isnt heavy at all, 630i manual weighs 1475 kg and 645i weighs 1690 kg. 630i is almost as fast as 645i due to weight and rpm advantages. The reason why people think its heavy, its because it looks massive but this 6 series uses light weight parts for example the fenders and the trunk are made of fiberglass. This 6 series was way ahead of its time
@@2011Transformersdotm yeah you right, I don’t really get why people hate on the 630. I bet most of the people complaining that it’s too slow haven’t actually driven one
I've owned a 2004 645ci vert for 10 years. It's definitely pleasant to drive and it has decent midrange torque & top end. Especially for only being 325hp/330tq. However, it's by no means a fast vehicle.
It is heavy at 3800 lbs for the coupe or 4,187 for the convertible. Especially for only having 325hp/330trq.
Thnks for vidéo
Np :)
The 645 smg is shifting like my grandma...
he he he he he he
thanks for the video..I am looking forward to buying a 645i, but looks a bit slow no ? 635d remap looks so powerful next to the v8 (even if it is not the same driving, sounding pleasure), what do you think about it ?
Do you have the feeling that the v8 pushes you in the seat ?
645 v8 all the way
635d would have to be re-mapped etc to get on par with a v8
(ridiculous torque Tho)
The v8 only comes alive top end, but by then ur doing stupid speed
(for roads)
It's wierd its more like power & pull that u feel. But no diesel is touching that sound! It purrs beautiful at 2-2.5k revs, & sounds awesome when u accelerate hard (especially in tunnels) v8 all the way..... Nice & smooth too!
@@SCD-BOY thanks my friend
@Sean Davies I do agree with you about the v8 sound and I would go for v8 instead of diesel simply for the driving pleasure alone . I had 630i and in city in sport mode it does put you in seat sou no doubt v8 would . However 635d would be faster then 645 hands down . I love e63 sou much that one day I will buy this car again , but this time I will go for v8 for sure . I was debating wether to take diesel performance over petrol sound and driving pleasure and my simple conclusion is that diesel just doesn’t go together with a sports car , plus you can remap v8 and add few horses to it .
Andrejs Gorjacko facts, 6 series and diesel doesnt fit for that big coupe, definitely a no go
630i is better, cheaper to maintain and more likely to resale.
This is very true!
grigorio allegri everything is not maintenance cost ! 645 ci is roaring on the road 😀 to listen gives person to huge happiness
Wrong! 645 doest have to work as hard as the 630 and barely any fuel difference when both being driven sensibly. I see the 630 as pointless. That's why i got a 645 and it's a beast!
@@pagjake mate, you don't know much about cars.... and even less about present car market ....
@@SLR-722 really???? Ok then! An engine that has to labour more uses more fuel. That's a fact! It's not what you drive it's how it's driven.
Is that normal running temp on the 645? (100-120'c)
It is depends on many factors!
@@Shabbe02
Such as?
@@SCD-BOY outside temperature, engine load etc
Some BMW engines have higher operating temp, like N55 105-110 is normal.
For my 645ci from 2004 it was indeed normal to have temperatures between 105 to even 125 °C (only when pushed hard on longer stretches). I did not have any issue with it though, just checked oil level regulary and changed engine oil, every 10.000 to 15.000km in general.
Small difference for 75 hp
Interesting, isn't it?
@@muldix Then there is the 630i lci with the N53 engine, 272 ps instead of 258 and 320 nm of torque instead of 300. Probably no difference
@@Shabbe02 but much less reliable!
@@muldix not really, the n53 has its problems but most of them are similar issues that the n52 has, the unique problems for each engine is coils, injectors and hpfp for the n53 which is not really a problem any more since updated versions have come out. And for the n52 is valvetronic which the n53 does not have.
@@Shabbe02 Which one to choose for rvery day? Which is more profitable for every day??? Thanks.
If one turbo that 630i and its going to be a reall killer :)
And then biturbo the 645 :)
@@maxdippininmylolo6421 there is one thing though with inline 6 you have one chian tensionner
one chain
and the motor is lighter
645 biturbo would be a beest but tbh a turbo 6 would me as equally a killer and had more space under the hood and lighter front.
id go with the 6cyl turbo :)
Supercharger on 645ci will compete with new camaros mustangs and will gap scatpackslet alone rebuild the whole motor then supercharge it it's competing with helcats
645i is far quicker then a shitty 630, maybe a faulty car or bad driver. believe me, i have one since 4 years
Why do you trashtalk the 630i? Its far more reliable than your 645i, besides its still a 6 series bmw and if you really would own one you wouldnt talk crap like that
@simjusu6385 I'll say this they are both good have pros and cons I own a 645ci 630d gets better gas mileage and fuel conservative tho if you want more torque and power gains 645ci is the way to go but 630d would be easier to work on
The end of the line is the N53/n52 Engine is the biggest trash of the world btw .... yes maybe its not so slow vor 3000cc okey
maybe he have a a nice sound but all other things that realy importet are is TRASH so many mistake in the Engine build are not coincidence.
THE V8 the SAME .. i MEAN HOW THE FU TAKE AN WATER PIPE BY THE OIL Container ?????
You talk trash, n52b30 is the best modern bmw engine bmw has ever made. Indestructible engine and power in one. N53 is trash, I agree, that engine has many flaws but not N52
@@2011Transformersdotm i got an n52 and know what im talking about. This car are 50/50 in parking lot or at repair station.
I agree extreme oil consumption and vanos failure
I have a 325i 2005 e90 n52b25 and it uses about 1litre every 500km, and that’s on a good day. 140k km
@@2011Transformersdotm they common problems the n53 used to have is not relevant anymore since updated parts have come out. They are about the same now when it comes to reliability. Performance wise n53 is better but depends on version.
the 645ci 333bhp, you made a bad start or you hadn't the right tires on the 645, goodyear F1 summer is the right tire for that car.
