WHEN the A45 first launched it was packing 265kW and, once the Audi RS3 achieved a touch more, AMG pumped it up to a class-leading 280kW, enhancing the torque by 25Nm to 475Nm for good measure. And that was enough to reinstate as the world’s most powerful 2.0-litre hot hatch, never to be troubled since.
Now there’s this while new generation. Which conceivably could have kept all the good bits of before and still been class king. Except, of course, it hasn’t. AMG was probably bothered, for one, that the old car was just 0.1 seconds faster to 100kmh from a standing start than the Ingolstadt worrier. Also, this is a brand whose credo is based on continual improvement.
Accordingly, with transference to a new platform, they’ve gone and redone all the performance hardware. Comprehensively. Power climbs to 310kW, torque to 500Nm, 0-100kmh falls to 3.9 seconds and … well, life with this wee smasher becomes even more of a blaring blur.
Well, that’s how it looks. In reality, there’s potentially a point where fast is fast, and faster doesn’t really feel it. I’d imagine that were all editions to be brought together, I guess you would have little trouble rating their respective blast values and picking the one that has, on the hot hatch scale, just gone into the equivalent of a thermonuclear zone.
But among A45 constants is that it has always been so much about the thrusting rush. Every predecessor has offered what this one delivers so easily; the kind of heart-jolting accelerative excitement that normally only associates with roller coasters when they free-fall off the ride’s highest point.
So it keeps doing that. Just as it keeps on setting the mark for being a car that seems almost over-qualified for the job it undertakes.
As a rule of thumb, you can generally take it for granted that any carmaker, when heating up any family car – which this still is, being an A-Class by birthright – will approach the process with some extra consideration and enthusiasm. But the AMG is more than that; the processes that involve here are astounding exacting, perhaps not to the point of overkill, but certainly to a level where the word ‘perfection’ seems to translate as ‘borderline acceptable’.
Assuredly, some owners will wonder why it needs as many performance functions or even why it so patently factors in performance abilities that, let’s agree, are well beyond reach in our driving environment, even on some racing circuits, and perhaps even the average level of engagement.
Fair point? Well, maybe, though I think the colleague who reckons it has somehow become so good as to be sanitised is missing the point.
For sure, it is a car that enforces you’d have to be driving like an utter loon – and then some - to reach beyond the point where it cannot cope. There’s a massive zone in which it will behave at a level that is as intoxicating as it is incredible, to the point where it will make you question all you thought you knew about physics.
And yet as much as it does all that, it also gives greater acknowledgement to the probability that some drivers haven’t the skill level to meet its capabilities, and accordingly gives them a better chance when they mess up. Yet on the other hand it also plays to expectations of those who do have the talent.
You imagine it already very devilish in the daily drive modes, which reach to Sport, but turn the dial further into Race and it assuredly so much more evil evidences that you realise PDQ that with this car, there’s extreme and there’s EXTREME.
The throttle sharpness is so much greater, every bit of the grunt is availed, it revs more readily to 6750rpm, which is where peak power occurs, and anything beyond light throttle translates into extremely quick forward motion. The latency is obvious when pegged at a standstill as the car positively quivers.
The exhaust note, too, finally releases the pop-bang, so reminiscent of Group A rally cars of old, that used to avail so easily in the first-gen car. Enforcing the seriousness here are the bonus facilities of launch control and drift modes; each open on presumption you already have a handle on the basics of their technique. Chucking an all-wheel-drive car into a slide is still a tricky business.
As always, it isn’t shy in announcing the insanity. The test car’s special yellow paintwork, which is all part of the Edition 1 treatment, is barely necessary, because so much more about the car’s appearance draws attention anyway.
Those 90mm diameter quad exhaust pipes sitting either side of a diffuser marked out by two vertical twin fins, there to help to suck the rear of the car down – also the job of the big angled spoiler on the top of the boot lid and the dive planes jutting out of the DTM-ready front spoiler - the huge 360mm cross-drilled front discs and accompanying six-piston callipers sitting all too obviously behind the fat tyre-shod 19-inch alloys, plus all the performance shop stuff inside – in this case, including heavily-bolstered front chairs that are a no-cost option to wider, more roadcar-style types, plus the requisite flat-bottomed and flat-sided steering wheel in Alcantara and complete with yellow twelve o'clock marker on the top … all lend very obvious clues to it being intended for rather more than a shopping run.
Those used to the old cars will find easily acquaintance with the new, save that they’ll search in vain for the stubby central gearshifter.
Notwithstanding that the new approach - shifting, when things get busy, by way of the now larger, alloy paddle, one on each side of the steering column, and then fine-tuning adjustment with chubby multifunction switchgear on the wheel hub – presents a more appropriate tie-in with Mercedes’ F1 involvements, and definitely delivers good result from the new AMG Speedshift eight-speed dual-clutch auto, I do miss the shifter, if only because it looks far more ‘pro’ than what we get now: The Mercedes’ 101 of a plastic column wand to engage Drive, Reverse, Park and Neutral.
The dials you’ll play with most are the shortcuts that can be set up for the damper settings and active exhaust, or something else should you prefer and another that lets you toggle through the different drive modes. Elsewhere, the broad double display setup of the MBUX infotainment system stretches across the top of the shallow dashboard and it’ll also impart loads of performance-specific info, in addition to undertaking all the everyday functions dedicated to infotainment and the like.
The active and fully variable 4Matic Plus all-wheel-drive transmission with its AMG Torque Control is a thing of beauty. Power is distributed between the front and rear axles, with torque vectoring by brake on the front axle and a more advanced twin multi-disc clutch setup on the rear. These electronically controlled clutches offer total variability in power distribution across the rear axle.
So it’s good to go. And go, and go. And though it can accommodate drivers who are compelled to keep it in Comfort mode and tootle within the posted limits, to the point of offering a reasonably cosseting ride and even some decent degree of comfort – notwithstanding those sports seats are probably only good for a couple of hours – it’s really designed to drive. Hard.
The most rewarding section of a two-hour final run was the quite country road section that was done and dusted in 20 minutes. On that piece, the reward was intense: The car was all but telepathic.
It’s really hard to see how the A45 could be improved. Except, of course, they’ve already managed to do just that three times already. So, undoubtedly, it will be.
Shame the price has to be so stratospherically high, though the one consolation is that A45s are among those AMGs that seem to hold remarkably good residual value. Surely that’s as much a nod of acknowledgement to their special qualities as anything else?
