Ironic, isn’t it?
We’re in Germany to drive the most recent all-electric area ship from BMW, but ending up with a no-holds-barred drive within the first ever M5.
Certain, it wasn’t the primary full-fat M automobile to return from BMW Motorsport GmbH (dubbed ‘M’): that hall-of-fame standing fell to the gorgeous Giugiaro-designed M1 supercar that debuted in 1978.
However the E28 M5 actually gave true which means to the time period, ‘wolf in sheep’s clothes’.
The truth is, it did much more than that. Many say it was the E28 M5 that laid the very foundations of the sports activities sedan class itself, the place understatement was a part of the important DNA.
In comparison with the common E28 BMW 5 Collection, which itself was the benchmark business-class sedan of the day, the M5 tremendous sedan barely stood out.
The compulsory M5 badges on the radiator grille and rear of the automobile had been small and comparatively unpretentious, and gave nothing away to what lay underneath the bonnet or certainly the beefed-up chassis that made this game-changing BMW so revered.
Even the bodywork was delicate, properly virtually. The entrance and rear bumpers barely registered on the radar, aside from the small rubberised boot-lip spoiler and discrete facet skirts that added a bit extra resolve to the M5’s largely unpretentious look.
Seen solely to a rigorously skilled eye or M aficionado had been delicate wheel-arch extensions and a barely lowered profile – crucial due to the bigger wheel and tyre mixture fitted to the M mannequin.
All the great things was under decks, although. Beneath the bonnet sat a 3.5-litre, four-valve, in-line six-cylinder engine that first noticed service within the M1 highway automobile, solely within the M5 (and M635CSi) the wick was turned as much as develop much more energy.
The motor itself was designated M88/3 and characterised by its crossflow, light-alloy cylinder head, two overhead camshafts, 4 valves per cylinder, centrally situated spark plugs, digital engine electronics and particular person throttle valves.
All of this {hardware} meant the M5 developed an unrivalled 286hp (213kW) at 6500rpm and 340Nm of torque, which was not solely 9PS greater than the M1, but additionally greater than the Ferrari 328 of the identical period.
Consequently, it might go from a standing begin to 0-100km/h in 6.5 seconds with a high pace of 245km/h – incomes it the title of quickest four-door sports activities sedan on the earth.
This, when the M535i put out peak energy and torque of 160kW and 310Nm respectively from its 3.4-litre straight-six motor, or noticeably much less in case you lived in the USA.
It wasn’t simply the M1 engine that was tinkered with both. The chassis additionally bought some particular consideration within the type of monotube gasoline strain dampers, whereas the entrance brake discs had been internally ventilated.
Furthermore, the M5 benefited from a specifically designed anti-lock braking system, a extra sturdy five-speed guide gearbox, and a limited-slip differential given the additional hundreds it needed to take care of over common 5 Collection fashions.
That subtlety continued inside however for a number of key parts that instantly distinguished the M5 from its common stablemates, as luxurious as they had been.
Our impeccably offered check automobile was from BMW Traditional in Munich and was fitted with the non-obligatory sports activities seats that had been conspicuous for his or her thickly padded bolsters and embroidered M emblem on the again rests.
They’re astonishingly snug and electrically adjustable in each route by way of a financial institution of rocker switches both facet of the handbrake.
There’s one other M emblem on the peerlessly clear three-spoke steering wheel. Not a single button or change to be seen.
The dashboard is the standard BMW-style, driver-centric unit emblazoned with an old-school laptop and a stack of buttons for the stereo and air-con. And let’s not neglect the stubby little guide shifter full with full-strength M emblem signifying its high-performance standing and rarity.
Bear in mind, this technology M5 is from an period when real efficiency automobiles featured a guide gearbox – solely – this being a five-speed Getrag unit.
All this efficiency and exclusivity got here at a value. It began from a minimal of DM80,000 however most consumers would find yourself spending as much as DM90,000 at a time when the 328 GTS was just a few thousand extra.
However, whereas Maranello constructed greater than 8000 Ferrari 328s in GTS & GTB guise collectively, BMW solely ever hand-built simply 2241 examples of the E28 M5 – therefore its unmistakable rarity.
Up shut, within the metallic, it’s laborious to inform the M5 other than the common model, it truly is. Thank heavens for these M badges, as small and delicate as they’re as a result of except you are taking a peak underneath the bonnet, this automobile might simply be mistaken for an everyday 5 Collection with a gentle physique equipment utilized. M badges had been simply procured again within the day.
Its situation is solely very good contemplating this very instance will get routine thrashings from all kinds of various drivers – some good, some unhealthy, I think. Their repairs is completely the work of BMW Traditional’s fanatical group, most of them youthful than this M5.
There’s a real simplicity to automobiles of this period, regardless of the actual fact the M5 was thought of extremely subtle and cutting-edge, full with a driver’s journey laptop sitting to the best of the steering wheel.
Twist the correct old-school key on the right-side of the steering column and also you get that high-tempo starter motor whirring noise earlier than the straight-six fires. Devoid of infantile farts, pops and crackles, there’s no mistaking it for a labored engine with its understated burble.
I’m cautious to get the oil strain up and the coolant temperature good and heat earlier than shifting into first and heading out of Munich to some quieter, greener pastures near an airport.
Naturally, you begin out with a little bit of apprehension realizing how a lot effort the parents at BMW Traditional put into the maintenance of those older machines. However apparently, that doesn’t imply it’s important to pussyfoot round.
I’m following one of many Traditional guys in his personal totally labored E36 wagon, and he isn’t hanging about. The truth is, he’s pushing laborious into some fairly severe corners on some not-so-busy B-roads, so I fortunately reply with a downshift and a boot stuffed with throttle.
It’s a motor that likes to rev however by no means sounds prefer it’s underneath an excessive amount of stress even on the high of the rev vary. Not lazy, thoughts, however far more sonorous as soon as the rpm nudges 5000rpm. It truly is a superbly responsive engine.
Because of its naturally aspirated state, throttle response can be deliciously linear, in order to permit minute changes in energy supply, that are completely crucial in my try to stick with the three Collection wagon forward.
He’s not slowing down, both. The truth is, he’s not even trying in his rear-vision mirror. I don’t suppose he cares. My type of lead driver.
The M5 has bought loads of punch in all of the decrease gears, too, however you get the most effective out of it shifting later within the rev vary, simply earlier than the torque curve flattens out. It’s no rocket like so lots of at this time’s automobiles however progress is each satisfyingly swift and massively pleasing all the identical.
The gear stick is understandably old-school and the throws between gears are lengthy, however it nonetheless feels deliberate. The tempo of the lead automobile in entrance calls for fast shifting, however it’s not a field that may be muscled. Finesse works greatest right here.
There’s some apparent lean on sharper turn-ins, however it doesn’t appear to have an effect on the dealing with, so that you are inclined to go even more durable and brake even later. You actually can throw the outdated M5 round, as examined by way of the limitless chicanes round these elements.
The chassis feels properly sorted and offers properly with its modest 1430kg (by at this time’s requirements) heft.
Previous mate forward is clearly having a ball in his wagon and pushing even more durable (I feel he’s making an attempt to lose me) due to his beefed up suspension with the most effective bits M has to supply. There’s zero physique roll in that factor, even at pace.
The sound of the E28 M5 from the mid-to-high vary is simply so good. Correct motorsport-derived engine constructing at play right here and nonetheless sounding just like the enterprise 37 years later, though this specific instance was one of many final constructed, in 1989.
I’m peddling as fast as I’m ready to go in such a uncommon machine which I don’t personal. To suppose it’s 33 years on and may nonetheless be correctly hustled in a no-holds-barred trend is massively spectacular to me.
Journey consolation is suitably comfortable, too, regardless of the M5’s enhanced suspension tune. Actually, I’ve pushed automobiles at this time that don’t deal with or trip in addition to this automobile almost 40 years on from its launch.
A few of that’s right down to the high-walled Micheline tyres (225/55 collection), whereas the remaining is right down to the extra forgiving suspension tune of the day. It makes for a much less frenetic drive expertise except you’re going as laborious because the man in entrance.
The ability steering is weighted accurately, too. Good and meaty however there’s a little bit of play either-side of the straight forward. You get used to it fairly shortly however not with out some shuffling and a little bit of arm-twirling at occasions given the scale of the leather-clad tiller.
It’s nowhere close to as exact as at this time’s EPAS outfitted M automobiles, however I’d argue there’s good suggestions.
Curiously, I additionally jumped in for a fast blatt within the E39 M5, which after all was a demonstrably extra sorted car, however it simply doesn’t supply the sense of engagement the E28 affords.
Because of BMW Traditional for the chance to thrash its E28 M5.
