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.Â

Mercedes-Benz AMG GT
"A racing car with street legal approval". Those are the words Mercedes-AMG uses to describe its GT R Coupe.
And even though I'm a forty-something, professional motoring journalist who's well aware of marketing speak when he reads it, the 15-year old in me was jumping around whooping and shouting: "Key! Gimme key to race car" at the launch of the updated Mercedes-AMG GT coupe which also included time in the more sedate GT C.
Well, that's like calling a Tiger Shark more sedate than a Great White, because the GT C still packs more than 400kW (550hp).
As will be the case with most buyers, my time in the Mercedes-AMG GT was spent entirely on the road, the closest we came to a racetrack was driving through Kilmore, and that one was for horses.
This was perfectly fine because you'll want to know just what these beasts are like to pilot on regular roads... roads where surfaces are far from perfect and the posted limits are hundreds of kilometres below the top speeds of these cars.

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.

Mercedes-Benz AMG GT8.1/10
The AMG GT is better than a race car for the road because it offers all the comfort and luxury that is completely absent in a track car, yet retains superb dynamic ability – particularly the GT R.
As for the sweet spot, that's easy. The C Coupe offers the best of the S and R from a comfort and handling perspective, while being super quick for less money that the top grade R.

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 AMG GT10/10
There is nothing not interesting about the design of the AMG GT with its long bonnet and low, wide stance. The look is not as dramatic as the SLS AMG, which went into retirement five years ago, nor does it have that supercar's 'gullwing' doors. But there's a clear family resemblance to it and also the iconic 300SL beauty from 1954.
If anything, the AMG GT is a meaner and sharper looking beastie, but still dripping in exotic styling with the hungry looking 'Panamericana' grille flanked by hornet eye headlights and enormous wheel guards that push up into the bonnet to form pontoons over which the driver peers.
It's hard to tell from the images if the AMG GT is big or small, but the dimensions don't lie. The AMG GT is 4551mm end-to-end, 2007mm wide for the GT R and GT C but 1939mm for the GT S (and between 1260mm and 1288mm tall depending on the grade, making it fairly long, wide and short in stature.
There are three grades to choose from - the GTS, GT C and GT R – which all come as coupes, while only the GTC is available as a soft-top roadster, as well.
I can't think of a convertible which doesn't look better with the roof down than with it up and the GT C is no exception to this rule. The open top suits this cruiser's look perfectly.
Telling the three grades apart is easy if you know what to look for: the GT S is a 'narrow body', the GT C has wider rear guards and the GT R has wide rear and front guards.
From behind there's a smoother rear treatment to the S with no wide black vent between the tail-lights, while the GT C has vents behind the rear wheels and the GT R has the most aggro look with the giant diffuser and a central tailpipe.
Exterior styling has stayed the same save for the new LED headlights, wheels and paint colours, but it's the cabin where most of the design changes have taken place.
There's the new steering wheel with drive mode dials and a redesigned centre console with buttons configured in a V-shape which according to Mercedes-AMG is a nod to the V8 engine.
I'm not convinced by the restyling of the console, which didn't suit me ergonomically. It seems to centre around the two cupholders, places the shifter awkwardly rearwards of the media controller and puts the traction control button directly under the driver's elbow. The black piano plastic in the GT R also became smudged with fingerprints quickly.
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. Â
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 AMG GT6/10
All AMG GT Coupes and Roadsters have two doors and two seats. If you need seating for more there's the AMG GT 4-door which can fit five adults (well, four comfortably) and competes with the Porsche Panamera.
So, if it's just you and a significant other you'll be happy to know the AMG GT cockpit is spacious and even at 191cm tall and with the same wingspan I had more than enough head, shoulder, elbow and legroom.
Cabin storage is limited to a pair of cupholders, a small centre console bin and door pockets just wide enough for a small bottle of water.
Boot space in the Coupe is 175 litres and 165 litres in the Roadster. That was just enough room for the two airline overhead luggage-sized wheelie bags belonging to myself and co-pilot.
As for charging and power on board there are three USB ports and one 12-volt outlet.
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 AMG GT8/10
The entry point into the three model range is the GT S Coupe with its $311,142 list price.
Stepping up to the GT C will cost $329,843 for the Coupe and $355,242 for the Roadster, while the GT R king of the castle commands a list price of $361,042.
Standard features on the S include nappa leather upholstery, heated and power-adjustable seats, AMG Performance steering wheel, panoramic sunroof, 10-speaker Burmester sound system, a 10.25-inch touchscreen with sat nav, Apple CarPlay and Android Auto, 'Mercedes Me' connect system, a 12.3-inch virtual instrument cluster, LED headlights, plus alloy wheels (staggered 19-inch at the front and 20-inch at the rear) with a matt black finish.
You'll see all these S features on the GT C along with more in the form of AMG Performance seats, AMG Performance steering wheel clad in 'Dinamica' microfibre, heated and ventilated seats and staggered 19-/20-inch alloys in titanium grey.
The GT C Roadster has identical features but adds a neck heater, which works surprisingly well.
The GT R comes with the GT C's features and brings its own in the form of the AMG 'Interior Night' package, a carbon-fibre roof, static rear wing and yellow brake calipers.
Porsche's 911 GT3 is a good rival for the AMG GT R, but undercuts it by about $35K, while a Jaguar F-Type SVR is $297,242 and Audi's R8 tops out at $425,500 for the Spyder.
So, is the AMG GT good value? Sure is, when you consider what you're getting relative to what the competitors are offering.
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 AMG GT9/10
All AMG GTs have a 4.0-litre twin-turbo V8 with three states of tune: in the S it makes 384kW/670Nm; in the C it produces 410kW/680Nm; while the output in R is 430kW/700Nm.
A seven-speed dual-clutch automatic transmission is used in all three grades.
All three grades have top speeds of more than 300km/h (318 in the R Coupe; 317km/h in the C Coupe; 316km/h in the C Roadster and 310km/h in the S Coupe) and 0-100km/h times of less than four seconds (R -3.6s, C - 3.7s, S - 3.8s).
Before you start wondering why the R costs $30K more to go one kilometre per hour faster than the C we need to talk about the hardware under the cars that makes the top-grade AMG GT worth the extra money in the section below.
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 AMG GT7/10
This might surprise you, but the official combined fuel consumption of the AMG GT S is 9.5L/100km, while the GT R's is 11.4L/100km, and the GT C's is 11.5L/100km.
The best combination of driving over motorways and country roads for me on this launch was in the GT R, and after a couple of hundred kilometres the trip computer told me the car was using an average of 12.9L/100km.
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 AMG GT9/10
The only grade missing at the launch of the updated AMG GT was the S Coupe. So, while I'm sure it's darn good, I can really only comment about the driving experience of the R Coupe and the C in Coupe and Roadster forms in which we devoured hundreds of kilometres.
First, the R and C both have unique characters that go beyond just differences in horsepower.
The GT C uses the front axle set-up of the GT S with its aluminium double wishbone suspension, anti-dive, coil springs and stablisier bar offering a more supple and cushioned ride, and combines this with the rear axle of the GT R with its rear-axle steering and more pinned down dynamic focus.
The GT R's front axle is also aluminum double-wishbone but comes with braking torque support, mechanically stepless adjustable coil springs, adaptive dampers and an anti-roll bar.
So, while the GT C and GT R feel different to pilot, it's not night-and-day different... more early summer morning sunrise, and midday sun beating down different, if you know what I mean.
See, while the GT C feels just as quick, it's a far more comfortable and easier car to drive on course-chip bitumen and pock-marked Australian roads. The ride while rolling on 265/35 R19 rubber at the front and 305/30 R 20s at the rear is surprisingly pleasant.
Country road corners beckoned on our journey out of Melbourne and the GT C Roadster I set out in responded superbly. That front end felt light, soft and but pointable. What was immediately apparent was how wide the car is, and it felt like the GT C needed every millimetre of the narrow Aussie lanes.
Top down there was almost zero air turbulence in the cabin and while I kept an eye out for the scuttle shake that can come with a convertible, I barely noticed anything along those lines with those short thick A-Pillars holding firm.
Also holding firm was the GT C's rear end which squatted and held tight in the corners even with getting on the gas the roadster stayed composed.
Roof up, most road noise was shut out, well it was hard to hear anything over the bellow of that V8.
The GT C Coupe would be my pick of the AMG GT family and not just because of that smidge of extra boot space. The hardtop just bolsters the overall rigidity of the car and made it feel tauter.
The GT R is a step up in price, grunt and dynamic ability, but it's asking for a higher level of commitment in terms of livability.
The ride on its firmer suspension and 275/35 R19 rear tyres and 325/30 R 20 front rubber makes the GT R more brutal than most people would be happy to live with, I think.
But in return you are getting close to that "racing car with street legal approval" positioning, because the GT R is astounding in its balance, handling, grip and the connection it offers with the driver.
Truly engaging and almost wasted on a regular road, but why it's not quite a race car is that the cabin is dripping in luxury from the beautiful and supportive standard seats, to the leather upholstery and digital instrument cluster.
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 AMG GT9/10
Coming standard on all AMG GTs is AEB, blind spot warning, lane keeping assistance, traffic sign recognition and adaptive cruise control.
All cars in the line-up come fortified with airbags, including a knee bag for the driver, side bags for the driver and passenger (combined thorax/pelvis bag), front airbags and window bags (Coupe only).
Front and rear cameras and auto parking make life easy, and while there's no spare wheel there is an inflation kit for temporary puncture repair.
A two-seater car the AMG GT doesn't have anchor points for child seats.
The AMG GT has not been assessed by ANCAP or Euro NCAP for its crash safety performance.
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 AMG GT7/10
The AMG GT has a three-year unlimited/kilometre warranty and along with BMW and Audi it's short compared to the coverage offered by more affordable brands.
Servicing is recommended at 20,000km/12-month intervals. Mercedes-AMG offers a three-year plan which costs $3750 up front or you can pay as you go with capped price servicing at $800, $1000 and $2950 for each respective year.
