In the direction of the top of final 12 months, we pitched the Alpina B3 Touring towards the BMW M340d and Birds B3-40i for a 3 Series wagon face-off. All three have been terrific in their very own approach (we have since welcomed the M340d onto the PH Fleet) however it did not stop the B3 towering above its extra inexpensive rivals within the verdict. It was too quick, too luxurious and too ingratiating to not win. An excessive amount of like an Alpina, in different phrases: construct a watertight case on paper, then carry it residence in the true world in a approach that apparently eludes a lot of the competitors. BMW included.
Now it is the flip of the diesel-powered D3 S within the UK. In contrast to the B3, which preceded the brand new M3 by half a 12 months and due to this fact did not must undergo direct comparability with BMW’s headliner, the D3 may be very a lot based mostly on the M340d – a mannequin that is been constructing a strong case for itself over the previous few months. It shares the identical primary 3.0-litre mild-hybrid straight-six and related AWD drivetrain, and doesn’t promise prodigiously extra from both. Outright energy is up from 340hp to 355hp; peak torque climbs by 28lb ft.
There’s not an unlimited disparity on asking value both. The M340d Touring at present begins at £52,045; the D3 S, £55,950. Clearly there’s in depth ticking potential on each side (our long-termer tops out at £62,615 and Alpina’s check automotive is £70,760) however each vehicles come as customary with a beneficiant quantity of package, together with an electronically managed limited-slip differential for the again axle and the all-important adaptive suspension.
Styling alterations apart, overhauling the chassis supplies the D3 S with its most distinguished level of distinction. Many of the {hardware} modifications spearheaded within the B3 are carried over, which means you get the uprated Eibach springs and bump stops alongside new anti-roll bars. The damper charges have been revised too, and 1 diploma of destructive camber is launched to the entrance axle. The identical tailored ALP-designated Pirelli P-Zeroes characteristic on the 20-inch solid alloy wheels (assuming you’ve got correctly opted to pay the £2,080 premium over the five-spoke 19s).
It’s the accumulative impact of those modifications that ship instantly on the acquainted Alpina promise. By any measure, the M340d supplies its proprietor with a deftly managed compromise between the customarily conflicting calls for of journey and dealing with – but the D3 makes it appear to be a job half finished. Usually it’s a case of noticing what will not be there: the minor palpitations that the BMW succumbs to when M-grade suspension and run-flat tyres meet poor surfacing at pace are nearly completely absent. The suppression of any abruptness from the automotive’s preliminary spring journey is notable not only for the positive aspects in refinement, but in addition for the superior sense of connectedness that comes with it.
Whereas nonchalance within the face of pot-marked tarmac is clearly a bonus within the UK, it is the consistency of the response and its relationship with cannily managed roll charges that mark the D3 out as a terrific steer. There is no float or flounder to the adaptive chassis in ‘Consolation’ mode when urgent on, simply the impression that the automotive will allow you to lean into its refined maintain on the street with abandon. Even when lumbered with BMW’s texture-light variable steering, there’s treasured little sense of aloofness or detachment. The D3 is the type of automotive you savour driving at any pace.
On this respect, the reworked diesel lump is nearly a greater companion for Alpina’s wagon than the 462hp straight-six strapped to the B3. Positive, it is a second slower to 62mph and never almost as good to take heed to – however the tuner has all the time preached some great benefits of heavy-duty torque, and 538lb ft from 1,750rpm is a relative superabundance even accounting for the Touring’s 2,010kg kerbweight. The brand new peak is underwritten by a bigger intercooler and improved cooling system, and whereas it is not considerably faster than the M340d, it appears subtly smoother and faster to reply.
That is useful as a result of it is seemingly you may drive the D3 subtly faster than the BMW. Alpina has fettled the parameters for each the xDrive system and the rear diff, however the M340d already possessed a wholesome desire for its again axle. The distinction is driver mindset. Geared up with a surfeit of flexibility, poise and no little tenacity, it is laborious to dial again an method that seeks to take advantage of all three, on a regular basis. The ‘Sport’ drive mode provides no reduction both: resistance-heavy steering apart, it simply makes the D3 hunker down that bit extra, surge ahead that bit extra brusquely, and slash but extra minutes from predicted arrival occasions.
Once you get to the place you are going, you are likely to look again longingly, too. The Alpina soaks up appreciative glances no much less effectively than it does bumps. The designers haven’t overindulged: there’s the identical gently reworked entrance and rear bumpers as appeared on the B3, with 4 chrome tailpipes exiting the latter. Nevertheless it is sufficient to ship the contentment gland into overdrive. Ditto the inside, which, when you ignore the contemptible dials, is a really nice place to be as soon as you’ve got factored in £1,900 price of Merino leather-based trim.
Factoring in further spend is de facto what the D3 is all about. It’s a class act, no query. However one should actually care about class to understand it. Quick wagons, particularly oil-burning ones, are usually likeable as a result of there’s one thing of the workhorse about them, and the cheaper M340d fills out that position greater than adequately. It goes like stink, sips like a hummingbird, blends in like cornflour and accommodates no finish of muddle. In the event you claimed to see no level in parting with extra for a automotive that implies it’s no faster on paper and but walks the quoted economic system again from 44.1mpg to 37.2mpg, it might be laborious to mount a convincing argument.
However I will attempt. The D3 S is the M340d as it might be in an ideal world. Alpina takes the premium and spends a few of it on meaningfully higher parts. It reorders a few of BMW’s developmental priorities. It genuinely asks itself what a eager driver would respect day-to-day, after which units about reaching it. The strategy has produced some excellent street vehicles, and the newest D3 S is amongst them. As a method to an finish the M340d is already an overachiever. However Alpina’s model is one thing else. It’s the greatest and most fascinating diesel-powered automotive you should buy interval.
