Maserati MC20 vs Audi RS5

What's the difference?

With a 320km/h-plus top speed and the ability to get from rest to 100km/h in under three seconds, there’s no doubting the MC20 meets or exceeds its performance brief. But when you’re paying these prices, there must be more than just the measurable stuff going on.

And there is. The MC20 brings a big dollop of purity to the ranks of current supercars, doing away with all-wheel drive and hybrid tech and relying instead on and old-school approach in terms of handling and overall feel.

Anybody who wants to argue that call has plenty of alternatives to the MC20 from other manufacturers, and for some of us, that less-is-more thing will ring true.

It's hard to look past the fact that the RS 5 Sportback is more than $50k more expensive than an S5 Sportback, which itself is hardly cheap. But is it the pick of the RS 4 and RS 5 family? Probably, but I’m personally still a sucker for the RS 4’s wagon shape

I also reckon it’s currently the pick of the three fast German options, and I love that you can get it in this bodystyle.

Perhaps the most striking thing about the MC20’s design is that it’s so restrained. You won’t find wings, vents, fins and diffusers all over the car, but rather an overall shape that creates downforce, rather than that job falling to tacked on additions.

And, like any modern supercar worth its salt, the MC20 is based around a carbon-fibre tub for rigidity and low weight. From that tub structure are hung aluminium front and rear subframes which, in turn, mount the suspension and other mechanical bits.

The wind tunnel still got a huge workout in the car’s development, of course, but the aim was to integrate the downforce-inducing elements rather than having them demanding your optical attention.

As a result, the whole car is an upside-down wing, if you want to simplify it. But a very pretty upside-down wing.

This gives the MC20 a smooth, sleek look that stands it apart from the rent-a-racer crowd and supports the theory that sometimes, less is, indeed, more.

Some of the detailing is lovely, too. The vents cut into the Perspex rear windscreen form Maserati’s trademark trident shape, there’s lots of visible carbon-fibre inside the door jambs, there’s lashings of Alcantara inside and the two-tone body kit breaks up the shape perfectly.

Elements we’re not so sure about include the 'Park' button mounted way down low under the dashboard, and the swing-up, scissor-type doors, which, if your more than about 180cm tall, still require you to duck under them.

On the upside, the carbon-and-leather steering wheel with its integrated controls is gorgeous to hold and gaze at.

From the B-pillar forward, the RS 5 Sportback is identical to the Coupe, with the same deep and aggressive front apron to set it aside from the lesser S5 and A5 models. The same applies at the rear, with a bespoke rear bumper with large oval exhaust outlets on either side.

It also scores the delightfully pumped wheelarches on each corner of its mechanical siblings, along with the same 20-inch wheels.

Like the coupe though, one detail that seems to be missing from the previous RS 5 is a significantly wider track. Compared with the S5 Sportback, the RS 5 Sportback’s track is just 11mm wider at the front and 20mm at the rear, so if you halve those figures per side they’re likely just from additional camber in the wheel alignment settings.

So those wheelarch blisters are largely for aesthetics, rather than a necessary adjustment to allow for a broader stance.

Enough of the comparisons though, the five-door liftback bodystyle gives it a uniquely sleek yet practical appearance, with all of the tasty performance cred of the coupe and wagon.

Also as I alluded before, BMW is unable to build you an M4 Gran Coupe, which would be its BMW equivalent, due to the regular Gran Coupe being built in a different factory to the 3 Series sedan and 4 Series coupe. And Mercedes-AMG’s C 63 bodystyle options are limited to sedan, coupe, wagon and convertible - there just isn’t a five-door liftback on the list.

The RS 5 Sportback’s interior is a continuation of the beautifully detailed coupe and wagon, with real carbon fibre, aluminium and leather tastefully applied leather that has a subtle edginess that really fits the Audi RS brand.

Although the MC20 has a front and rear luggage compartment, they’re both small enough to be pretty much useless. This is a shame, because as a long-weekend getaway car, the Maserati otherwise makes a strong case for itself.

The other area that suffers for the car’s art is the interior practicality. While the driving position is great and the pedals and wheel relationship is spot on, when it comes to storing anything, you’re on your own. Best the MC20 can offer is a single cupholder at the rear of the central tunnel.

The mid-engined layout also means there’s precious little vision through the back window. To counter that, Maserati has fitted the MC20 with an interior rear-view mirror that can act as a conventional mirror (you can still see only the engine) or as a screen for the rear-mounted camera.

The catch is the image projected to the 'mirror' lacks depth of field and forces the driver to refocus on the image rather than simply glance at it.

This is where it’s hard not to make Goldilocks analogies. Where the RS 5 coupe has a decent boot with a small, sedan-like opening and a back seat for two that’s difficult to access via the front doors, the RS 4 has a great wagon boot with a huge opening and a back seat for three that’s easy to access because it has back doors.

The RS 5 Sportback is closer to the latter, but sacrifices the cargo height of the wagon and the sloping roofline will mean that taller passengers may want for more headroom and easier access to the back seat. It does retain the wagon’s third seating position back there though, and neither back seat compromise is an issue for my 172cm height.

Its 480 Litres VDA seats-up boot capacity is a match for the S5 Sportback, which is only 25 litres short of the RS 4. Like the S5, a space saver spare sits beneath the boot floor.

The RS 5 Sportback also ticks important convenience boxes like dual cup holders front and rear, bottle holders in each door, decent oddments storage and auxiliary connections front and rear, plus ISOFIX child seat mounts for both outward rear seat positions.

If you’ve ever found yourself perusing Audi’s mid-size RS line-up and been disappointed by the lack of back doors in anything without a wagon body, the RS 5 Sportback is the solution.

Two door coupes are a pain to live with unless you have no need for the back seat, and I’m led to believe that there are some who aren’t enchanted by the RS 4 Avant’s epic cool factor.

If this is you, and your local freeway onramp isn’t long enough to suit the S5 Sportback’s 4.7s 0-100km/h claim, you’ll also be delighted to know that the RS 5 Sportback is priced at the same $157,700 (before on roads) as the RS 5 Coupe, and $4800 above the RS 4. You won’t be as delighted by the $51,900 premium over the S5 Sportback.

The standard equipment is a match also, with the Quattro sport rear differential, RS sports exhaust and 'Dynamic Ride Control' with adaptive dampers all on the list.

You’ll also find the black 'Fine Nappa' leather sports seats with diamond stitching, Bang & Olufsen 3D audio, LED headlights, gloss black exterior details, panoramic sunroof and red brake calipers.

The Audi virtual cockpit driver display also features, plus RS-specific tyre pressure, torque and g-force readouts and a shift light.

The RS 5 Sportback aligns with the MY19 RS 5 coupe spec upgrade, which brings a head-up display, wireless phone charger and USB outlets for rear passengers.

The RS 5-exclusive 'Sonoma Green' paint seen on the coupe is also now available on the Sportback for the same extra $1950 any colour aside from Nardo grey will add to the sticker price.

One detail you don’t get on the coupe is the auto liftback with gesture control, similar to the RS 4’s tailgate.

Previous generations of Maseratis borrowed Ferrari (both brands were once part of the extended Fiat Chrysler family) technology for their drivelines in a deal that allowed both brands to share the cost of development.

And since having a Ferrari-built engine in your car was never seen as a sale hindrance, it was a sweet deal for Maserati. But when Ferrari was spun off and became a publicly-owned company in 2016, Maserati’s supply of engines dried up.

The solution was to take engine design in-house and the twin-turbocharged 3.0-litre V6 in the MC20 is one of the first fruits of that.

While it’s undoubtedly a high-tech powerplant, in other respects it’s fairly conventional. Maserati, for instance, has a long history with the V6 layout, and there’s no hybrid element to the driveline. Nor is there a hybrid option.

Maserati claims the V6 is the world’s most powerful six-cylinder production-car engine and, with no less than 463kW at 7500rpm and 730Nm between 3000 and 5500rpm, that’s a credible statement.

Technical details that you won’t see on most road cars include a dry-sump lubrication system (where the engine oil lives in a remote tank rather than the hot sump of the engine itself) and a sophisticated fuel injection system with two injectors per cylinder.

The real trick, however, is an ignition system with two spark plugs per cylinder. There are also effectively two combustion chambers, the first ensuring multiple flame fronts to achieve a more complete burn of the fuel in the main combustion chamber.

The rest of the driveline is similarly aimed at the purists out there; the transmission is an eight-speed dual-clutch, driving not all four wheels, but only the rears through a mechanical limited-slip differential.

Selectable drive modes from GT (the default setting) through to 'Wet', 'Sport', 'Corsa' (Track) and 'ESC Off' tailor the shift points, throttle sensitivity and suspension behaviour, but still allow for full engine power.

The RS 5 Sportback is a genuine mechanical match for the coupe and RS 4, which means the same and impressive 331kW/600Nm 2.9-litre twin-turbo V6 and delightfully adaptive eight-speed ZF torque converter auto.

Max power is available from 5700-6700rom, while peak torque is accessible all the way from 1900-5000rpm.

The Quattro all-wheel drive system retains it 60 per cent native torque bias for more of a rear-drive dynamic. 

Fuel economy is probably not going to be top of mind for most MC20 buyers, but the official combined figure of 11.6 litres per 100km is still pretty greedy by 2022 standards.

Balanced against the available performance, however, and an engine making more than 600 old-fashioned horsepower with that combined fuel-economy number is still cause to reflect on modern technology and efficiency.

The MC20 has a 60-litre fuel tank, making it a handy cross-country car for weekends away.

Given the familiarity of the RS 5 Sportback’s mechanical package, there’s also no surprises with its fuel consumption.

The official combined fuel consumption figure is 8.9L/100km, which is 0.1 more than the coupe, and the same as the RS 4.

We managed a rare feat during our 350-plus kilometre drive taking the back way from Canberra to Goulburn, to Oberon, then to Bathurst via Lithgow, where we managed to match the official combined figure on the car’s trip computer.

While it’s a good rule of thumb that you can do this on a steady motorway cruise, it was mighty impressive to do it along the flowing country route with regular climbs and overtaking.

It is worth noting though that like all RS models, the RS 5 Sportback commands expensive 98 RON Premium unleaded as a minimum.

Here’s where your half-a-million bucks has gone.

The MC20’s acceleration is absolutely shattering and is all the more amazing for the fact the car uses neither all-wheel drive grip nor hybrid torque to achieve its sprinting abilities.

While the V6 is not the most sonorous of powerplants, it does manage to sound high-end and pretty sophisticated and it’s never as shouty as some of its opposition which seem to confuse decibels with kiloWatts.

While the sheer thrust confirms the existence of two turbochargers, the lack of lag (or throttle delay) and the ability to charge into the rev limiter in the lower gears does not.

Even though power peaks at 6500rpm (as with many a modern turbo motor) the MC20 will happily smash on to the redline at 8000rpm; sometimes too happily if you don’t have your finger over the upshift paddle. As with other good modern turbocharged units, this one doesn’t actually feel overtly turbocharged.

The transmission shifts relatively smoothly in GT mode, but as you crank up the mode selector to Sport, the shifts become very fast with an accompanying jolt through the backrest as each gear clicks home. The shifting process is fairly foolproof, although you do get full over-ride, so you need to pay attention.

Both the cars we were able to sample at Philip Island were sporting the optional carbon-ceramic braking package, and one was also fitted with the optional 'birdcage' alloy wheels which are lighter.

Each of them needed a firm shove on the pedal to slow things down, but it’s true the lighter wheels seem to be worth their almost-$3000 ask as that car required less leg-pressure for the same result.

The lack of a hybrid element to the driveline, as well as the rear-drive layout, suggests a degree of purity of purpose in the car’s design. And that’s backed up by its behaviour in the first corner.

Fundamentally, instead of just hurling it at an apex and allowing the electronics to sort it all out for you, the Maserati requires a more 'classical' technique if it’s to really shine.

It doesn’t, for instance, reward trail-braking (where you continue to brake once you’ve turned into a corner) and would much prefer you get your braking over and done with before applying any meaningful steering lock.

Ignore this, and the rear weight bias of the mid-engined layout can see the car try to yaw, with the rear end becoming light and the vehicle over-rotating (which is a spin, to you and I).

Similarly, getting on the power before you’ve actually got the MC20 turned, can unload the front end and send the front wheels ploughing (ploughing is an exaggeration, but at the speeds we’re dealing with here, even a small degree is a big deal) towards the outside of the turn.

Ultimately, then, the technique becomes a text-book case of brake, turn and then power out, at which point the MC20 reveals itself to be huge fun and incredibly fast. The only thing to deal with then is the knowledge that whatever happens next is going to happen extremely quickly.

There’s a good chance you’ve skipped straight to this point, and if you've driven the excellent RS 5 Coupe or the RS 4 you won’t find any surprises in the RS 5 Sportback. This is a very good thing.

Compared to its muscular looks, its general refinement around town is still a really nice surprise for a car of this performance calbre. It’s not hard to imagine driving your grandmother around in comfort. In fact, she would have been right at home on our 350-plus kilometre country cruise between Canberra and Bathurst. 

You might miss the V8 growl from an AMG, but the V6 does make a nice bark once you give it some decent throttle, and it delivers those 331kW and 600Nm very effectively through those two turbos. As I often find myself saying these days, this thing is so easy to drive so fast!

Its very impressive 3.9 second 0-100km/h claim feels entirely realistic, which matches the coupe and trumps the RS 4 by two tenths.

You probably won’t be surprised to hear that the ZF eight speed torque converter auto feels right at home with the RS5, being smooth as around town, and as responsive and quick to shift as you’d ever want it to be when you’re getting up it.

Its overall refinement does mean it’s not quite as exciting to drive fast as the AMGs or BMW Ms, even with the controls and mechanicals tightened up in Dynamic mode.

Our best opportunity to put it through its performance paces was via the surprise set of bends hidden between Bathurst and Sofala, where it simply honked its way uphill. You instantly forget that it's a rather large five seater with almost room for a pony in the boot. There’s miles of grip, it steers really nicely and the big brakes do a really good job under pressure. This, is a proper RS.

While not specifically stated, the RS 5 Sportback should be covered by the same five-star ANCAP safety rating as the rest of the fixed-roof A5 family. Note that this rating was awarded based on older 2015 criteria though.

It matches the RS 5’s impressive list of standard safety features, which includes front city AEB with pedestrian detection.

Interestingly, the initial Sportbacks being delivered to Australia match the six airbag count of the coupe, which covers front and side airbags for the driver and passenger, along with curtain airbags covering the front and rear.

The second batch and all future RS 5 Sportback examples will match the eight airbag count of the wagon, which adds rear side airbags to the list above. If you’re about to place an order, I’d strongly recommend insisting on the eight airbag version that this score is based on.

High-end cars often disappoint on the details, and the Maserati is no different here, offering just a three-year factory warranty (albeit with unlimited kilometres).

That trails even the most humble commuter cars these days, and suggests there’s still a degree of indifference from some carmakers. And, possibly, their customers.

There is, however, the option of fixed-price servicing for the MC20 with the first three years’ worth of servicing costing $4000.

Scheduled services are every 15,000km or 12 months, whichever comes first.

Like all Audis, the new RS 5 Sportback is covered by a three year, unlimited kilometre warranty. This is short of the five year-plus periods that now form the status quo among mainstream brands, but equal to the terms offered by BMW and Mercedes-Benz. Lexus differs by offering a four year, 100,000km plan. 

RS 5 Sportback service intervals are a generous 12 month/15,000km though. 

Another detail to be aware of is that RS models are still exempt from Audi’s Service Plan Pricing capped price servicing plan.
