All-new S3 is M135i's closest rival in spirit, price and spec ... or is it?
The manual car's slim, flat bottomed wheel and characteristically light-actioned and precise shift are all familiar Audi features, likewise the fierce grab from the brakes and brittle springing at low speeds. The engine pulls strongly from low revs, with little sense of lag and a muscular mid-range but it doesn't feel 10 per cent up on power compared with the Megane 265 or Focus ST. And lacks the M135i's 'OMG' punch. It also seems to headbutt its limiter very hard and about 500rpm sooner than you expect, the traditionally undersquare design happier at low revs than close to the redline. Which, unfortunately, is just where the BMW has a glorious finale to its power band, its revvier oversquare nature and six-cylinder balance really coming through. On a test drive that'd seal it, especially if you've got the Audi in the 'Dynamic' engine noise mode that sounds more like a misfire.
Audi's been listening to complaints about hard ride set-ups though, both the standard dampers and adjustable ones on the Sportback striking an acceptable balance between 'sporting' firmness and bump absorption and poise.
Four-wheel drive does give the Audi an all-weather advantage over the tractionally challenged BMW, which will give you a lot of flashing lights on the dash when it's wet. But while fun to hustle along and effectively fast, there's little thrill factor at the Audi's wheel and it doesn't inspire like the M135i can along the same piece of road.
The 1 Series' looks remain divisive and the fact your colleagues and neighbours won't be able to tell the difference between your M135i and an entry level 114i will rank it hero or zero according to taste.
'Civilian' non car folk will probably be more impressed by the Audi, especially blinged up with a few extras like the red seats of our manual car or the quilted 'Super Sports' ones in the Sportback. But that's not really the PH way - is it?
Meanwhile, in the real world...
No getting away from it, the BMW is a selfish choice based around the driver. Front seat passengers will probably be telling you to slow down, rear seat ones moaning about the lack of leg and head room. And the fact the shopping that should be in the boot is probably in their lap. There are benefits to being based on VW's MQB hatch platform though, with space and practicality definitely on the S3's side. Simply put, it's more likely be the one to get universal household approval.
Do they compare on price?
Yes, spookily so. A three-door manual M135i costs Â£30,570, the comparable S3 Â£29,980. Looking up the range a five-door M135i auto starts at Â£32,595, an S3 Sportback with S Tronic Â£31,920. Both S3 and M135i have standard leather, sports suspension, respective S and M Performance branding ... and expansive options lists. Which brings us to...
Do they REALLY compare on price?
The fact the bottom line on the five-door Sportback we tested starts with a '4' is probably the first shocker in this comparison, though it's fair to concede that this car was a fully laden press car with all the toys. But the fact the S3, already on the back foot for power and punch in the guts performance, can weigh in with a 10 per cent price premium over a generously specced five-door auto M135i is eye opening.
the A45 AMG, again faster and with a standard dual-clutch gearbox, starts at Â£37,000. Have a browse of the full options specs and prices below and make your own decisions about what's necessary and what could be trimmed. But it's hard to escape the fact the S3 quickly blows any price advantage with a few options ticked.
The S3 is a great car by any measure. Well, any but this one sadly. In all but practicality and, to some eyes, pose value it's hard to escape the fact the M135i thumps it comprehensively across the board. If you need a more family orientated premium uber hatch the Sportback will be a much more convincing sell than the more self-centred BMW. But for the kind of feelgood factors we're looking for it's not a hard one to call.
