Audi S5


Mercedes-Benz SL-Class

Summary

Audi S5

It's inevitable that Audi's S5 will spend the bulk of its time pouncing between traffic lights in Australia's clogged and cramped CBDs, but it's hard to imagine a better place to enjoy the hard-charging antics of this stunning Coupe than the sublime twists and turns of Tasmania's perfect blacktop.

Based on the also-very-pretty A5 Coupe, the S-stamped version adds a powerful 3.0-litre V6 engine, a quick-shifting eight-speed gearbox and some suspension trickery that glues the sleek Audi to the road surface below.

It's the fastest, most powerful and lightest S5 to date, and it's cheaper than the car it replaces to boot. And better still, we had an entire island neatly wrapped in perfect ribbons of tarmac to put it to the test.

The second-generation version of the S5 Sportback is set to appear in May, while the new S5 Cabriolet will follow later this year. For now, the two-door Coupe will lead the charge.

Mercedes-Benz SL-Class

An SL sports car has been part of the Mercedes-Benz line-up since the early 1950s, and when I think of this model I see that golden years of Hollywood star (with the great hairstyle) Yul Brynner, in the late 1950s cruising the French Riviera in his 300SL roadster. Or Sophia Loren regularly posing with her 300SL Gullwing coupe around the same time.

Over seven iterations and more than seven decades it has stood for performance, glamour and exclusivity. And after a two-year hiatus the Mercedes-AMG SL63 roadster has made a comeback to the Australian market.

Verdict

Audi S58.1/10

The kind of car that pushes back the autonomous argument, the S5 Coupe is a fun and frantic blast from the behind the wheel. Addictively powerful, sharp to steer and with the kind of endless grip that turns a twisting road into your own personal amusement park, the S5 injects a ton of fun into back-country blasts. It might be a touch uncomfortable in the city, but that's a price we're willing to pay.

Does a V6 turbo Audi S5 trump the previous V8 version? Tell us what you think in the comments below.


Mercedes-Benz SL-Class8.4/10

The new Mercedes-AMG SL63 4Matic+ is guaranteed to turn heads for decades to come. But there’s enormous design and engineering substance underpinning this car’s undoubted good looks. Stunning performance, superb dynamics and top-shelf safety make this a powerhouse GT to be reckoned with.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

Design

Audi S59/10

Undoubtedly one of the better looking cars on the road today, the Audi S5 Coupe looks sleek and stunning from every angle.

Viewed front-on, the newly designed single-frame grill (it's now wider and flatter) looks slick and powerful, while a raised bulge in the bonnet (Audi calls it a power dome) hints at the performance lurking beneath it.

Side on, a body crease (so sharp it's like it's been cut with a laser) runs the length of the body, while the 19-inch wheels are perched at the furthest corners. Four burbling exhausts emerging from beneath the boot complete this perfectly painted picture of intent.


Mercedes-Benz SL-Class9/10

Rather than a strict two-seater, this time around the SL adds the flexibility of ‘+2’ rear seating while the previous 'Vario’ folding hardtop has been binned, the new car returning to a traditional, electrically-folding and weight-saving (-21kg) soft top. 

Mercedes-Benz design chief Gorden Wagener started the new model’s development from a ‘clean sheet’ and Mercedes-AMG says “not a single component comes from the predecessor SL, or any other model such as the AMG GT Roadsters”. 

Always a subjective call, but I think this car’s proportions are just about perfect. The lengthy bonnet with its twin longitudinal ‘Power Domes’, raked windscreen and fat haunches create a wide stance and presence that’s almost impossible to ignore.

Aggression, as with the sinister headlights and 21-inch rims, is subtly combined with soft curves along the flanks and around the rear. Note the seamless door handles.

And it’s not all about aesthetics. Active aero has been integrated into the front apron and retractable rear spoiler. Plus the ‘Z-fold’ roof design does away with the need for a separate cover.

The interior is sub-zero cool with slick screens, an 11.9-inch display covering multimedia and a 12.3-inch unit for instrumentation ahead of the driver, being particular highlights.

Turbine-style air-vents at the leading edge of the split-level dash and alloy trim elements are a tip-of-the-hat to SLs past and the deft mix of large flat surfaces with complex curves oozes design confidence.

Practicality

Audi S57/10

Well, the hint is right there in the name. This might be a touch over 4.6m long, but that swooping coupe roofline eats away at your practicality, especially for rear seat passengers.

Up front, though, it's spacious and comfortable and built for purpose, with terrifically bolstered sports seats and a flat-bottomed steering wheel that's among the best in the business.

Shift to the back, and you'll find two seats (the middle one has been replaced by a weird plastic table), but there is plenty of legroom. Headroom, on the other hand, is a less positive story, with anyone who is 183cm (six-foot) or taller are sure to become well accustomed with the S5's roof lining.  

There's a cupholder in each of the rear doors, matching the two for front seat passengers, and two ISOFIX attachment points in the back row. Backseat riders also get their own air-con controls, and a power outlet.

Boot space is what Audi claims is a class-leading 465 litres (up 10 on the outgoing car) and the rear seat is split 40/20/40.


Mercedes-Benz SL-Class8/10

In the context of a high-performance GT, practicality is pretty impressive.

At just over 4.7m long the SL is a sizeable machine and much of its lengthy (2700mm) wheelbase is devoted to making the driver and front passenger comfortable.

There’s plenty of space for that pairing and just enough storage to cope with the ‘things’ they’ll typically bring with them.

Door pockets offer enough room for a few odds and ends, although you’ll struggle with even a medium-size bottle unless you’re willing to lay it down horizontally along the top of the aperture.

A handy lidded bin between the front seats doubles as a centre armrest, there are two cupholders under a sliding lid in the centre console and the glove box is a decent size. 

Power and connectivity options run to four USB-C ports, a 12-volt socket and the wireless device charging pad.

Then there are the rear ‘+2’ seats, and Mercedes makes no bones about the fact they’re intended for occasional use only, even suggesting a 1.5m occupant height limit.

And there’s no doubt they offer a handy emergency seat or a fun kids’ zone. Just ask a Porsche 911 Carrera owner how much this kind of seating arrangement increases a sports car’s flexibility.

At 183cm I gave the back seat a crack, which meant sliding the front (passenger) seat way forward with the backrest close to upright. But I squeezed in, and there was just enough legroom for a person in front at the same time. 

With the roof in place there’s the added pleasure of cranking your head over to around 45 degrees. But it’s do-able! 

No storage, adjustable ventilation, or power back there. But that’s fair enough, especially given there are USBs available in the front centre storage box.

Boot volume is 240 litres with the roof up and 213 litres with it folded, which is enough for some light luggage, and not too shabby when you think a Toyota Corolla hatch offers up just 217 litres (with all seats up).

There’s a 12V socket in there, but don’t bother looking for a spare, in the event of a flat your only option is a repair/inflator kit.

 

Price and features

Audi S58/10

Audi's new S5 Coupe arrives with a sticker price of $105,800, which is a touch over its most obvious competitor - the marginally slower BMW 440i Coupe.

The good news, though, is that you'll want for little, and can easily avoid Audi's infamous options list. Expect 19-inch alloy wheels that display the bright red brake calipers, illuminated door sill trims, nappa leather sports seats that are heated in the front, and offer pneumatic bolster and lumbar support, plus carbon detailing in the interior.

In-cabin technology is taken care of via Audi's awesome 'Virtual Cockpit' (a huge digital screen that replaces the traditional dials in the driver's binnacle - the Google Earth-overlayed navigation is particularly outstanding) along with a second, centred screen that feeds a 10-speaker stereo.


Mercedes-Benz SL-Class8/10

Priced at $373,370, before on-road costs, the new SL63 4Matic+ will be battling top-shelf performance soft tops including (in ascending dollar order) BMW’s M850i xDrive Convertible ($307,100), the Porsche 911 Carrera GTS Cabriolet ($386,900) and even exotics like the Lamborghini Huracan RWD Evo Spyder ($422,606). 

Value for money is a relative concept in this part of the market, although equipment highlights include a head-up display (with augmented reality nav), 11-speaker, 650-watt Burmester surround sound audio, ambient lighting (choice of 64 colours), hectares of Nappa leather trim, dual-zone climate control, an 11.9-inch central multimedia screen (running Merc’s latest ‘MBUX’ software), 12.3-inch configurable digital instrument display and 21-inch forged alloy rims.

There’s also the ‘Digital Light System’ built around three high-power LEDs in each headlight, refracted and directed through 1.3 million ‘micro-mirrors’ to create a combined resolution of 2.6 million pixels.

The ‘Neck Scarf’ function is added to the top of the front seats to keep your neck and the back of your head warm as the temperature drops, the heated, ventilated and massaging front seats feature eight-way electric adjustment and three memories, there’s a heated steering wheel, Android Auto and Apple CarPlay connectivity, wireless device charging and more.

Worth noting the big 21-inch rims in a ‘10-twin-spoke’ design are standard issue with an alternate ‘multi-spoke’ pattern available as a no-cost option. 

But if all that’s not enough you can opt for ‘AMG Performance seats’ ($2490) which grip you even more securely but delete the massage function.

Or there’s the ‘AMG Night Package’ ($6990) which adds wheels in matt black (with “high-sheen finish rim flange”), darkened head- and tail-lights, an aero package, black badging, black radiator fins and interior trim elements in black chrome.

Then you can go the whole hog with the ‘AMG Carbon Fibre Package’ ($11,990) which brings the wheels in matt black, exterior carbon elements, carbon mirrors, carbon interior trim and a steering wheel in a combination carbon-fibre and Dinamica (synthetic microsuede).

Under the bonnet

Audi S59/10

The S5 Coupe's engine is an absolute peach, with a thick and steady flow of power that can make you forget a V8 version ever existed.

The turbocharged, 3.0-litre V6 is good for 260kW at 5400rpm and 500Nm from 1370rpm, channelled through a sensational eight-speed automatic gearbox and on to all four wheels. It's enough for a 4.7sec zero to 100km/h time and a limited top speed of 250km/h. But the sprint is only half the story, with the engine's mid-gear acceleration offering an insanely addictive rush of power when overtaking.


Mercedes-Benz SL-Class10/10

This new ‘4Matic’ all-wheel-drive SL63 features AMG’s (M177) 4.0-litre twin-turbo V8, superseding the previous rear-wheel-drive SL’s similarly configured 5.5-litre unit.

Hand built by one AMG technician from start to finish, it produces 430kW (around 580hp) from 5500-6500rpm and 800Nm across a broad plateau from 2500-5000rpm.

It’s something of a mechanical masterpiece, and the previous seven-speed auto transmission, driving the rear wheels only, has been replaced by a nine-speed dual-clutch auto (with wet multi-disc start-off clutch) sending drive to all four wheels via Merc’s ‘4Matic’ AWD system.

Efficiency

Audi S57/10

Well, Audi puts the number at a claimed/combined 7.5L/100km, but if you drive the S5 anything like you should, then you'll see that number climb skyward like its just been launched into space.

The S5 Coupe's C02 emissions are pegged at 171g/km.


Mercedes-Benz SL-Class7/10

Mercedes-AMG’s official fuel economy number for the SL63 on the combined (WLTP) cycle is 13.9L/100km, the 4.0-litre twin-turbo V8 emitting 319g/km of CO2 in the process.

On the roughly 300km launch program we covered urban, B-road and some freeway running, returning an (indicated) average of 17.5L/100km. And that reflects some enthusiastic driving along the way.

The fuel tank requires 70 litres of 98 RON premium unleaded to fill it which translates to a theoretical range of around 500km, dropping to 400km using our real-world number.

Driving

Audi S59/10

Addictive. The power delivery from that S5's V6 is rich and constant, and there's useable urge lurking all over the rev range. The sprint from 0-100km/h is enticing enough, but it's the way the car climbs from 90km/h, 100km/h or 110km/h when you plant your foot, a surging wave of power kicking you in the base of the spine as the S5 Coupe blasts you into the future.

The steering tune is bespoke to the S5, and it's the only model in the A5 range that arrives with adaptive dampers as standard fit, allowing you to dial firmness into the suspension, as well as tightening up the steering, gearing and throttle response.

As a result, it is an absolute joy to pilot through bends, sitting low and flat throughout before making use of its all-wheel drive to hurtle out the other side. It's the stuff involuntary smiles are made of, and you're unlikely to ever tire of it.

For day-to-day use, however, it sits just on the firm side of comfortable, which might grate on pockmarked city road surfaces, but the engine, exhaust and steering weight are all muted enough to ensure it can double as a quiet and composed commuter.


Mercedes-Benz SL-Class9/10

I recall driving the AMG SL65 around the backroads of Tassie a few years ago and that twin-turbo V12 monster famously packed 1000Nm of torque, while this car ‘only’ has 800.

But there comes a point where enough is enough… and this is enough!

With maximum torque available from 2500-5000rpm and peak power (430kW) on call from 5500-6500rpm there’s always stupendous acceleration available with a squeeze of your right foot.

Claimed 0-100km/h time is supercar fast at 3.6 seconds, while top speed is a toupe-troubling 315 km/h. And that’s electronically limited!

A typically ferocious engine noise and howling exhaust note accompany rapid progress and shifts from the nine-speed dual-clutch transmission are quick and positive, not to mention especially enjoyable using the steering wheel-mounted paddles.

There are six ‘AMG Dynamic Select’ drive programs from Comfort through to Race, the latter including a Drift Mode, which we didn’t experiment with. Nor did we dip into the ‘AMG Track Pace’ system for circuit-focused mapping and timing

However, far from drifting, the grippy Michelin Pilot Sport 4S rubber (275/35 fr - 305/30 rr) plants the car securely with the all-wheel-drive system and electronic locking rear diff playing their part.

I found the perfect set-up was in the ‘Individual’ mode with the engine, transmission and steering in racier settings and the suspension in ‘Comfort’. The adaptive damping in this configuration mixes smooth ride compliance with sharp dynamic response.

The car’s aluminium space frame chassis is part of a body structure mixing aluminium, magnesium, fibre composites and various strength steels.

Torsional rigidity is claimed to have been improved by 18 per cent and despite the lack of a roof the SL feels tight and solid.

Suspension is by alloy double wishbones front and rear with adaptive damping and active hydraulic anti-roll stabilisation standard (so, no physical anti-roll bars).

At the same time the 4Matic AWD system is able to vary torque distribution up to 100 per cent to the front or rear axle depending on where drive can be put to best use.

The speed sensitive, variable ratio, electronically controlled steering is accurate and turns in beautifully with good road feel. No doubt assisted by electric rear steering able to adjust the angle of the rear tyres by up to 2.5 degrees.

All this adds up to a hugely impressive package that, despite its 1970kg kerb weight, feels agile, athletic and able to attack corners like an overgrown hot hatch, putting its power down with unwavering authority.   

While indecently fast the SL63 can also stop rapidly with the AMG high-performance braking system standard. 

Huge composite ventilated and cross-drilled discs (390mm fr - 360mm rr) are clamped by six-piston fixed alloy calipers at the front and single-piston units at the rear. They wash off speed calmly and consistently with perfect pedal feel.

Even at highway speeds, particularly with the windows up, normal conversation is easy with the roof down. But if you need to raise (or lower) it, the operation takes 15 seconds and is possible up to 60km/h. 

Under the heading of miscellaneous observations, the turning circle is a not insubstantial 12.8m, so beware in the car park.

A front axle lift function is a welcome standard feature, raising the car’s nose 30mm with the press of a button. And lift locations are stored in GPS data, so the car will subsequently remember to lift itself at the same place, even if you don’t! 

Heating and cooling for the front seats combined with the heated steering wheel and Air Scarf neck warming makes winter top-down driving a pleasure.

The digital instrument display is not only crystal clear, it can be changed through multiple configurations, including a tunnel-like graphic for engine revs as well as specific readouts for speed, g-force, the lot.

At the same time, the central media screen’s angle can be adjusted to better cope with reflections and the windscreen wiper system Merc calls ‘Magic Vision Control’ channels fluid along the wiper arms onto the rubbers, which isn’t new, but works spectacularly well here.  

Safety

Audi S59/10

Audi has thrown just about everything it's got at the S5 Coupe, and the safety list is extensive. Expect six airbags (dual front, side and curtain), which join a reversing camera, parking sensors, forward collision warning with AEB and pedestrian detection, a rear-impact sensor, cross-path assist and a driver fatigue detection system.

The entire A5 range was awarded the maximum five star ANCAP safety rating.


Mercedes-Benz SL-Class9/10

No independent ANCAP safety assessment at this stage but the SL63 is fitted with the ‘Driving Assistance Package Plus’ which includes a heap of active (crash-avoidance) tech including AEB (with pedestrian detection), active cruise control, lane keeping assist, lane change assist, traffic sign assist, ‘Active Traffic-assist’ and ‘Active Steering Assist’. 

There’s also tyre pressure monitoring and the ‘Active Parking Assist with Parktronic’ self-parking system supported by a 360-degree camera view and multiple sensors. 

If a crash is unavoidable the airbag count runs to eight, including side bags for rear occupants. There are ISOFIX anchor points for child seats or baby capsules in the two rear and front passenger seat positions. And an active bonnet is designed to reduce injuries in the case of a pedestrian impact.

Ownership

Audi S57/10

The Audi S5 Coupe is covered by a three-year, unlimited-kilometre warranty, and requires servicing every 12 months or 15,000kms.

Audi offers the ability to pre-pay your maintenance costs for the first three years at $1,850.


Mercedes-Benz SL-Class7/10

The SL63 4Matic+ will be covered by Mercedes-AMG’s five-year/unlimited km warranty, with roadside and accident assistance included for the duration, both of which are expected in this category. 

Maintenance intervals are 12 months/20,000km, and a fixed-price service plan lists an average of $1583 for each of the first three visits to the workshop. Not exactly small change, but not unheard of in this part of the market.
