Life with a S5 Cabriolet: Month 3

Staying warm while looking cool in the S5 – 25 October 2017 The arrival of autumn is a reminder of how cold cabrios can get when the weather turns. I’ve been finding this out in the Audi S5[5], and discovering at the same time the usefulness of the rear windbreak, which I was previously rude about.

With it in place, you can cope in cold weather with the top down, so I like it now. Wish it looked better, though. Mileage: 9797

Life with a S5 Cabriolet: Month 2

Healing the S5 Cabriolet’s battle scars – 20 September 2017 The Audi came into sharp contact[7] with a deer a couple of weeks ago, as you might have heard.

Killed the animal, sadly, and mangled the S5’s frontal plastics, but at least the airbags didn’t go off. Audi’s phone recovery service was prompt and immaculate: the car was collected within couple of hours and now its repair is largely complete. We’re looking forward to its return.

It has taken a while, but I’ve finally got to grips with the configurable driving controls essential to full enjoyment of any Audi S5[8], and especially the cabrio, which is unusually satisfying at both extremes of its performance. Often in the cabrio, in the same half day[9], you’ll first need to cruise a motorway, top up to cut wind rush and other people’s tyre noise while the engine pulls fuel-saving low revs in eighth gear. If you’re lucky, your journey will take you to a place where you can glide quietly along country roads with the top down, enjoying rural sights, smells and vistas before maybe finishing the day with a sprint on favourite roads – for which you need full access to the 3.0-litre turbo V6’s 349bhp[10], via a transmission now configured so that it both sharpens throttle responses and isn’t nearly as keen on finding eighth gear for delivering maximum economy.

The transmission part is easy: pull the lever backwards and you’ll get Sport, which will either let you change manually on the shift paddles or give you an auto regime that ensures that the engine is nearly always operating between maximum torque and maximum power, with the smooth bark from the S5’s impressively purposeful quad exhausts[11] curling up to your ears across the car’s rear deck. But it’s how you use the Drive Select control, awkwardly located a stretch away on a little panel just above the centre console, that makes an even bigger difference.

Press it, and you’ll be offered a chance to select Comfort, Auto or Dynamic settings for the engine and gearbox, the suspension (magnetic shocks), the electric power steering, the rear diff (which tames wheelspin and dispenses torque vectoring) and the engine sound. You’ll soon tire of changing these settings all the time, especially since the switch stays live for only four seconds, which is too short a time if (like me) you are not especially dextrous. The solution is to decide your own settings for these five functions and then freeze them under the Individual selection.

If you care about such minutiae – and you will once you get to know the car – it takes time to reach an ideal. Mine is engine set to Dynamic, suspension to Auto (which assesses road surface action and makes its own decision), steering to Dynamic, diff to Auto and engine sound to Dynamic. My result is a sporty but fairly subdued engine, a quickened throttle response, firm steering that suits the system’s quick gearing and a diff that does as much as it can to keep me on line when powering energetically out of corners.

So far, I’m really pleased with the car, which couldn’t be better summer transport. Interestingly, Mr Editor Tisshaw, who has also done quite a few miles in this car, prefers Normal for steering and powertrain, saying that the car feels rather snatchy and ‘digital’ with the settings I prefer. He’s fresh from an M-Sport BMW 3 Series that, he reckons, followed a driver’s desires more naturally.

I’m not arguing: the main thing is that the Audi can accommodate us both[12]. Those who meet the S5 for the first time wonder[13] if it needs to be so big, ignoring the fact that you can buy an S3 cabrio if compactness is your priority[14]. But I’m enjoying our car’s character as a generously proportioned (fast or slow) cruiser.

Hope the summer lasts. Mileage: 6235

Life with a S5 Cabriolet: Month 1

Welcoming the S5 Cabriolet to our fleet – 26 July 2017 I’ve never had an Audi before. Nothing sinister about that; just that other people here got up earlier, which says something about the fundamental desirability of the marque in all its guises.

However, when the idea of being the de facto owner of the Audi S5 Cabriolet came up[16], I have to confess I was excited. Of course, I already knew drop-top S5s were handsome, sporty and powerful[17], but this recently revised, slightly larger model’s combination of an all-new 349bhp 3.0-litre turbo petrol V6[18], a nice, controllable eight-speed ZF paddle shift auto, and Audi’s latest infotainment system[19] was enticing, to say the least. The arrival of decent summer weather at about the same time as our car was a bonus.

Choosing the car’s spec was as challenging as ever for someone configuring a ?50,000 Audi. Any S5 comes well equipped[20], but we paused before we chose the handsome and rich Navarra Blue as the exterior colour (too dark for the summer?) and the grey quilted leather interior (too urban for this country dweller?). But good decisions, as it turns out. The ?1200 quattro system with sports differential chose itself: who’d deny himself class-best traction with a bit of torque vectoring chucked in?

Ditto the ?900 S suspension and adjustable dampers, which, I’m already finding, allow the car to be configured ideally for a wider-than-normal variety of British roads. I have to admit I jibbed a bit at ?1350 for advanced parking assistance. I doubt if I’ll ever use the self-parking, but I do regard front and rear sensors as essentials, and you also get a superbly clear reversing camera.

I love head-up displays, even at ?900, and I knew the ?750 Bang & Olufsen audio system and ?325 phone paraphernalia would help make journeys shorter. Folding mirrors make sense, and I happen to like flat-bottomed steering wheels. Stuff I wish I’d left out?

The ?50 Smoking Pack is obvious, plus the ?300 wind deflector (which is a dream destroyer to me, much like mudflaps). Besides, I’ve already proved that in open guise the cabin is largely free from buffeting[21]. I’d also consider losing the ?950 Dynamic steering (systems that go finger light at parking speeds feel horribly imprecise) and could live without the ?425 carbonfibre inlays in the cabin.

Last thing: I feel surprisingly resentful about being stung an extra ?175 for a Storage Pack, especially when you look at what it comprises: nets on the front seat backrests, a compartment under the front seats, a lockable glovebox and a cupholder in the rear centre armrest. Surely, in a car costing ?51,835 basic – and ?60,880 with options – this can be taken for granted, can’t it? I know in today’s PCP deals such things hardly make a quid-a-month difference, but it’s the principle…

And the driving? I’ve put 4000 miles under this car’s wheels in four weeks. In the Autocar environment, cars that accumulate big miles tend to offer the best combination of good times and ease of use – and the S5 Cabriolet delivers on both counts[22].

I have to admit, I paused over our test team’s ‘not quite brilliant’ verdict on a new-spec S5 Coup?[23], but their verdict was delivered against a background of harder-edged Mercedes-AMG[24] and BMW tarmac-chompers[25], whereas this car is definitely a cruiser. It’s a quick cruiser, mind.

Audi claims 5.1sec for the 0-62mph sprint. Plant it, and the car erupts; its acceleration all the better because the permanent four-wheel drive system allows no wheelspin at all in the dry, and only a chirrup in the wet. But you rarely drive it like that.

This is either a brisk or a leisurely cruiser. Pleasures include the smooth rasp of the exhaust, curling up to your ear over the rear deck from the impressive quad exhausts. The engine, which delivers maximum torque (369lb ft) from 1400rpm[26], is the soul of docility – even if it can also produce a decent yowl and plenty of thrust near the 6500rpm redline.

I had two concerns about running a convertible: one, that the motorway cruising noise level would make life hard; two, that the S5 cabrio would lack the body rigidity of space-framed sports cars[27] I’ve owned, and of the admirably stiff Mazda MX-5[28] I have now. I’ve now been far enough, fast enough to know neither issue matters. The multi-skin rag-top Audi is as quiet as a coup? when cruising[29] and also feels comfortably rigid over bumps. Such stiffness might have something to do with a kerb weight nearing two tonnes.

Despite the avoirdupois, the S5 cabrio feels nimble when you lean on it. The steering is nicely weighted, but not exactly special in a class full of superb contenders. But pitch it fast into bends, thinking it’ll understeer, and it just doesn’t, mainly because there’s plenty of 255/35 R19 rubber on the road, and because of the torque vectoring.

It completes the second half of bends neatly indeed, flattering your driving and emerging exactly on line. The ride, depending which of four driving modes you choose, varies from rock-hard jittery to quite soft and pitchy on rough suburban streets – just the kind of spectrum of adjustment you need. I usually choose second softest.

This is a capable and accomplished car, especially for the use we’ve so far put it to. We might find something different when the weather turns bad, but somehow I doubt it.
