Audi RS5 vs Aston Martin Vanquish

What's the difference?

Good looking, good to drive, and good to simply sit in, the Audi RS5 range ticks plenty of premium boxes. Whether you can live with the practicality pitfalls of the Coupe is up to you, but if you can't, might I suggest taking a wander over to our RS4 Avant review?

The definition of luxury is having something you want, rather than something you need. And the Vanquish is definitely something you don’t need, but will desperately want once you’ve experienced it. It’s opulence on wheels, the kind of car you buy mostly because you can. Because owning a V8-powered Aston Martin wouldn’t cut it in your circle of friends. Or because you just want the very best things in life, cost be damned.

I defy anyone to describe the RS5, and especially the Coupe, as anything but stunning. Seriously, the near perfect proportions and swept-back styling make it look fast even when it's parked. 

Up front, there's a new-look black-mesh grille that's been given a 3D effect, like it juts out over the road in front it, while the thing headlights have been carved back into the body work like they're been windswept under hard acceleration.

The 20-inch darkened alloys fill the arches, too, with a sharp body crease that runs from the front headlight all the way back to the bulging shoulder lines above the rear tyres accentuating the curves.

Inside, the RS5 is a sea of black Nappa leather and sporty touches, and we particularly like the chunky, flat-bottomed steering wheel, which both looks - and feels - great.

While the engine is the unique heart of the Vanquish, the design is the first element that grabs your attention. Even for a brand renowned for its GT cars with imposingly long bonnets, the Vanquish stands out.

That’s because the designers deliberately added 80mm of space between the front axle and the A-pillar (the front windscreen pillar) to elongate the bonnet even more for what it calls a “rakish and indulgent” profile. 

The lines flow across the length of the Vanquish, from its trademark grille to its Kamm Tail, giving it a look that is somehow simultaneously classically Aston Martin - with elements of its multiple generations of GT cars - while also being contemporary. 

Some of the modern touches are derived from Formula One, as the brand looks to leverage its racing team, with bonnet louvres to help cool the engine without unsettling the air-flow too much.

Aston Martin’s Chief Creative Officer Marek Reichman calls the Vanquish “an iconic halo model” and explained the design was deliberately pushing “beyond the expected, rational, and thoughtful.” Which sums up this dramatic piece of automotive art quite nicely.

We only tested the Coupe, and I can tell you that the practicality perks on offer largely depend on where you're sitting.

Up front, you're spoiled for room in the two-door Coupe, with the two spacious seats separated by a sizeable centre console that's also home to two cupholders and a variety of cubbies, with extra bottle storage in each of the front doors. 

The back seat, though, is a little, or a lot, tighter, with come acrobatics required to even climb into it, given the Coupe only has two doors. The Sportback offers two more doors, which will surely make the process a little easier. 

The Coupe measures 4723mm in length, 1866mm in width and 1372mm in height, and will deliver a decent 410 litres in luggage space in the boot. The Sportback measures in at 4783mm, 1866mm and 1399mm, and boosts your luggage space to 465 litres.

Either vehicle has your tech needs sorted, with an abundance of USB and power outlets serving both front and backseat riders.

Despite measuring nearly five metres long, the Vanquish is a surprisingly small car from a practicality perspective. Because the added wheelbase is ahead of the cabin, it remains strictly a two-seater, with no room for rear passengers.

There’s limited small item storage, too, aside from a couple of cupholders and a lidded console box. Although, on the plus side, the lack of rear seats creates room for some small shelves in case you need to store some loose items.  

It also has a surprisingly small 248-litre boot, which means limited storage for anything, including luggage, for a road trip in what would otherwise be a great road trip car.

As for the multimedia system, while not at the cutting edge (although Aston Martin will debut Apple CarPlay Ultra in its DBX model) the system works well for this type of car.

It’s unlikely too many under 25s will be grabbing this $700K luxury GT, so the fact the media system has a touchscreen and an array of physical buttons is a welcome detail.

As for the 1170-watt, 15-speaker Bowers & Wilkins sound system, it performs incredibly well, as you would probably expect. Like the car it has loads of power but excellent attention-to-detail with fantastic clarity, too.

The Vanquish sits at the top of the range for now, at least until the new Valhalla supercar arrives in Australia, and has an eye-watering starting price of $737,000.

Not only does that not include on-road costs, which will likely push the price closer to seven-figures, there’s also the plethora of options and customisation you can choose from that will add to the amount you pay.

Not that the standard specification is bad. For $700K you do get 21-inch alloy wheels, carbon ceramic brakes, 16-way adjustable sports seats, keyless ignition, a 10.2-inch touchscreen multimedia display, Apple CarPlay, Bluetooth, wireless phone charging and a 1170-watt 15-speaker Bowers & Wilkins sound system.

Of course, on top of all that you get a bespoke chassis and a unique twin-turbo V12 engine, that puts the Vanquish in the same class as the Ferrari 12Cilindri, which starts at $803,500 - making the Aston Martin look competitive. 

Its a terrific engine, this - a twin-turbo 2.9-litre six-cylinder TFSI that will deliver 331kW at 5700rpm and 600Nm at 1900rpm, sending it thundering to all four wheels (because quattro) via an eight-speed tiptronic automatic.

That's enough, says Audi, to deliver a 0-100km/h sprint time of 3.9 seconds in the Coupe and the Sportback. Which is very, very quick.

The engine is undoubtedly the star attraction of the Vanquish, with the twin-turbo 5.2-litre V12 being the last of its kind in the British brand’s line-up now that the DB12 has switched to an AMG-sourced twin-turbo V8. 

While that engine is arguably better with its excellent performance, smaller dimensions and lighter weight, the fact remains that for many of Aston Martin’s long-time buyers, it’s V12 or nothing.

It also helps that the V12 produces an extremely potent 614kW and 1000Nm, which is way ahead of the 611kW/678Nm the Ferrari 12Cilindri makes. So you get bragging rights at the golf club with your Ferrari mates.

The engine features a unique titanium exhaust and is paired with an eight-speed automatic transaxle that drives the rear wheels.

That is enough to propel the Vanquish to a top speed of 345km/h, making it the fastest production car the brand has ever produced, with a 3.3 second 0-100km/h time.

The RS5 Coupe will sip a claimed 9.4L/100km on the combined cycle, and emit a claimed 208g/km of Co2. It's fitted with a 58-litre fuel tank. 

The RS5 Coupe will the same 9.4L/100km, but emit 209g/km of Co2.

To say the Vanquish isn’t the most fuel frugal vehicle on the market is an obvious statement, but even its claimed 13.7L/100km is best described as optimistic.

That’s not surprising given its size and performance, but with an 82-litre fuel tank that’s a driving range of less than 600km, at best.

In the real world, during our time in the Vanquish, the car’s trip computer was indicating that we stayed in the high teens; although that featured limited freeway/extra-urban driving.

With our time behind the wheel limited to the RS5 Coupe, we can only really report on how the two-door feels on the road, but given the prodigious power on offer, it's unlikely the addition of two doors is going to make the Sportback any slower. 

In short, the RS5 is thunderously fast, collecting speed with utter nonchalance thanks to this thick and endless-feeling supply of power unleashed whenever you plant your right foot.

It makes even the most ham-fisted attempts at cornering feel fast as lightning, with the power flow able to make up for every slow entry and exit by simply piling on pace between bends. 

But that's what you expect from an RS model, right? So perhaps more impressive is the RS5's ability to transform back into a relatively sedate urban cruiser when the red mist subsides. The suspension is firm, especially over rough road surfaces, and you do need to be a little careful with the accelerator to avoid that lurching feeling at every green light, but driven calmly, it doubles as a everyday car quite nicely.

Like in the RS4, we did find the gearbox felt a little quick to change at pace, shifting up or down at strange moments on the way into or out of corners, but you can reclaim control via the paddle shifters.

As cars go, few can match what the Vanquish offers. Even in my 20+ years of driving every type of car imaginable, the Vanquish stands out as being something distinct, bold and special.

Sitting behind the wheel, the bonnet looks like it stretches out to the horizon and you feel like you’re sitting on the back axle of the car. And yet, when you start driving, the Vanquish feels like it shrinks around you.

At normal speeds it feels like a classic grand tourer, relaxed, refined and easy to drive. Obviously it's a firmer ride than your average luxury car, but that’s a small price to pay for the breadth of capability this car offers. 

Because once you get out of the urban environment, the Vanquish becomes something else entirely. On a winding road this British beast is surprisingly agile for such a big car.

The steering feels direct and the front end responds with much more precision and poise than you should reasonably expect from a car with such an exaggerated bonnet.

No, it doesn’t have the dynamic aggression the more compact Vantage offers, but it manages to take elements of that car and combine it with the GT nature of the DB12 to give you the best of both Aston Martin’s coupes.

Of course, the catch is it’s much too fast for Australian roads and isn’t really designed to be a track day car, so in Australia - without autobahns or more liberal views on speeding - the Vanquish in many respects doesn’t make sense.

But that is arguably its driving essence, you buy it because you know what it’s capable of, even if you’ll rarely use it, and that is an absolute luxury.

There’s no ANCAP rating given the extreme low-volume nature of the Vanquish. However, it does come with complete airbag coverage for both occupants and a laundry list of safety acronyms.

These include autonomous emergency braking (AEB), forward collision warning (FCW), adaptive cruise control (ACC), traffic sign recognition (TSR), lane keep assist (LKA), lane departure warning (LDW), blind spot assist (BSA) and rear cross-traffic assist (RCTA).

In addition there’s driver attention assist, to make sure you stay alert in such an expensive machine, and door exit assist, so you don’t open the long doors into a passing car or cyclist.

Importantly, none of these systems are intrusive or annoying, so credit to Aston Martin for integrating them smoothly.

Audi vehicles are covered by a three-year, unlimited-kilometre warranty, which is feeling more than a little underdone when compared to some competitors.

Services are due every 12 months or 15,000kms, and Audi allows you to pre-pay your service costs for the first five years, at a cost of $3,050.

Despite the extraordinary price tag the Vanquish is covered by a very standard three-year/unlimited kilometre warranty. It’s a surprising, and some might argue disappointing, short period of coverage for a car that is not only expensive but should have a long life.

However, it does redeem itself in some way by including the first five years of servicing into the cost of the car. Ferrari offers seven for its models, so Aston Martin is still behind the market, but included servicing feels right for a car costing nearly $1 million once you put it in traffic.
