Audi RS7 vs Lexus RC

What's the difference?

The new-generation RS 7 Sportback heralds the further evolution of this large majestic beast, with more features, a beautifully finished cabin and with more grunt with the looks to match. You’d be hard-pressed to find a better combination of power, dynamics and comfort in the Audi range – apart from in the RS 6 Avant of course.

If you’re a buyer that thinks with their head, the RC 350 F Sport is the obvious choice when compared to its direct rivals.

After all, it looks great (at least to these eyes), feels luxurious in more ways than one, and is unrivalled when considering value-for-money.

But, if you think with your heart instead, it’s clear it is isn’t on the same level dynamically and therefore doesn’t feel as sporty to drive as its name suggests.

So, don’t let its sports car classification fool you, the RC 350 F Sport is more of a grand tourer, or a comfortable cruiser, to be precise, and an underrated one at that.

The big news is the RS 7 Sportback now comes with five seats. The previous generation car had just two seats in the second row. I'll talk more on practicality below but for now let's examine the new styling.

This RS 7 Sportback has new broad, black mesh grille, flanked by gigantic side air intakes, narrow headlights, and a thin upper air inlet which is a hat tip to early racing Audis.

While that new angrier, more angular and menacing face is a showstopper, everything about the new RS 7 Sportback seems to be accentuated further.

Look at the wheels. The previous generation came with 21-inch rims, now the new normal for the RS 7 are 22-inches – they're huge. Those wheel guards also flare out 20mm more than a regular A7's and the rear haunches have bulked up massively.

Come to the back of the car and the diffuser and bumper have also been beefed up. Nobody sitting behind you in traffic is going to think this is just a regular A7.

Don't expect the RS 7 Sportback's insides to be just as hardcore as its exterior. The cabin is almost identical to a regular A7's. It's a stunning cockpit dominated by a dash which protrudes back towards the passengers and houses the media screen. Anther display for climate is set into the big centre console which divides the driver and co-pilot into almost cocooned cells.

The cabin isn't without its RS touches though – there's the sports seats with honeycomb stitching, fully digital instrument cluster with RS specific meters, the RS steering wheel, the Nappa leather on the dashboard and the doors, the aluminium inlays. The level of fit and finish is up there with the best that I've seen on any production car.

The RS 7 Avant is 5009mm long, 1424mm tall and 1950mm across for a wide planted stance.

Looking at the RC 350 F Sport, it’s hard to imagine how it became so anonymous on the road, whether you love it or hate it.

Up front, its striking design simply cannot be ignored, with its unique mesh 'Spindle' grille insert demanding attention.

Either side of it are the LED headlights and boomerang-style daytime running lights, which, again, cannot be missed.

Around the side, the RC 350 F Sport has all the hallmarks of a classic coupe, including a swoopy roofline, and looks all the better for it.

The 19-inch alloy wheels wrapped in a mixed set of Bridgestone Potenza tyres are particularly arresting thanks to their sporty 10-spoke design.

That said, the rear end is arguably the RC 350 F Sport’s best angle, at least universally, thanks to its crisp LED tail-lights and chunky bootlid.

The bumper below is also a looker, even with its fake side air intakes, while its diffuser insert is flanked by a pair of chrome exhaust tailpipes.

Inside, the RC 350 F Sport isn’t quite as good, with most of our criticism directed at the 10.3-inch central display, which is powered by an average multimedia system made worse by an incredibly fiddly touchpad controller. The physical shortcut buttons on hand are but small mercies.

Thankfully, Apple CarPlay and Android Auto support is now standard, so a better user interface is literally in your pocket… but you still don’t have a touchscreen to work with.

The RC 350 F Sport’s button-controlled 8.0-inch digital instrument cluster is much better, even if it’s more like a multi-function display due to its limited functionality.

While the centre stack and console designs are undoubtedly showing their age, there’s no doubting this is a premium model thanks to the selection of high-quality materials used throughout the cabin.

In our test vehicle, black leather-accented upholstery with (very cool) 'Tuscan Sun' yellow accents, piping and stitching covers the sports steering wheel, gear selector, sports seats, armrests, door inserts, knee rests and the instrument cluster. So, almost every touch-point.

Pleasingly, soft-touch plastics are used for the upper and middle dashboard as well as the door shoulders, with hard plastics only found on the lower dashboard, door bins and rear seat divider.

As per other Lexus models, the RC 350 F Sport has nice rose-gold accents on its steering wheel, gear selector, front air vents and centre console, while specific Naguri aluminium trim adorns its dashboard and door inserts. And there are also steel pedals.

The previous RS 7 Sportback was a four-seater, now it has five seats. That's right, a middle seat has been added to the second row, but, as you'd expect, it's not the best place be in the RS 7 Sportback, straddling the large driveshaft and ducking under the low roof-line.

That fastback profile does mean headroom in the second row is nowhere near as good as the RS 6 Avant's, but legroom is the same and, at 191cm tall, I can just fit behind my driving position with about 10mm to spare.

Up front it's not as spacious as you might think. That stepped dash protrudes into the passenger's space, the door pockets are thin and the centre console storage under the armrest is small.

Sportbacks are more practical sedans thanks the large opening offered by the hatch. The boot's 535-litre cargo capacity is great and only about 30 litres less than what you have in the RS 6 Avant.

For phones there's a wireless charger and two USB ports in the centre console storage box, while back seat passengers have two USB ports and a 12V outlets. There's also directional air vents and dual-zone climate control in the rear, too.

Hope you’re not expecting the RC350 F Sport to be the first word in practicality, because it’s not.

Measuring 4700mm long (with a 2730mm wheelbase), 1840mm wide and 1395mm tall, the RC350 F Sport is a decently sized coupe, but that doesn’t mean it’s spacious. Hell, it’s hard to get into it the first place, let alone out.

We are of course referencing the token second row, which is cramped at best. In fact, behind my 184cm (6.0ft) driving position, there is no toe-room nor headroom. Yep, if you’re around my height or taller, get used to burying your chin into your chest.

Thankfully, legroom is better but still limited to less than two centimetres, while foot space is compromised by the unusually tall transmission tunnel. And in case you were wondering, even the first row is on the tighter side.

Beyond the central air vents, you’d think rear occupants would be cheered up with cupholders, a fold-down armrest and USB ports at the very least. Well, they don’t get any of that, with a couple of coat hooks the only amenities on offer.

And don’t forget that being a four-seater, there are only two seats in the second row, so this is definitely not a ‘family car.' That said, there are two ISOFIX and two top-tether anchorage points for child seats, so you can theoretically take a couple of younglings with you on a trip.

In-cabin storage options are very limited, with the glove box small in size and mostly taken up by the manual, while the central bin is useable but somewhat occupied by two USB-A ports, a 12V power outlet, and an auxiliary input.

And whatever you do, only bring up to two drinks with you, as beside the pair of cupholders next to the gear selector, there is no other place to officially store extras. Yep, the front door bins are only good for storing very short and narrow items.

The boot is a different story, with a decent 374L of cargo capacity, and it can be expanded by stowing the 60/40 split-fold rear bench, an action that can annoyingly only be performed in-cabin via the manual release latches.

That said, the boot’s tall load lip makes unloading bulkier items a little trickier, while getting them onboard in the first place is complicated by its wide but short aperture. At least there are four tie-down points on hand to secure loose loads?

Priced from $78,636 plus on-road costs, the RC 350 F Sport commands $3000 and $8000 premiums over its lower-output RC300 and lower-spec Luxury siblings.

In terms of rivals, the RC 350 F Sport significantly undercuts the best-selling Mercedes-Benz C 300 Coupe ($89,000) but is about on par with the Audi A5 40 TFSI Sport Coupe ($78,900).

Standard equipment not already mentioned in the RC 350 F Sport includes rain-sensing wipers, power-folding side mirrors, satellite navigation with live traffic, digital radio, an 835W Mark Levinson sound system (with 17 speakers), keyless entry and start, dual-zone climate control, power-adjustable front seats with heating and cooling, a power-adjustable steering column and an auto-dimming rearview mirror.

Yep, it’s loaded, which is very good news. What isn’t, though, is its foot-operated park brake. Sure, the RC is six years old, but electric park brakes were well and truly a thing in 2014, so it’s quite an annoying quirk.

The RC 350 F Sport only has two options: a $2500 power-operated sunroof and $1500 premium paintwork, both of which were fitted to our test vehicle, with the latter taking the form of 'Graphite Black.'

The RS 7 may look like a large, well-mannered business class car, but think of it as a thug in a suit because this thing is a monster with a 441kW/800Nm twin-turbo petrol 4.0-litre V8.

That's almost 600 horsepower and the supercar acceleration that goes with it is brutal: we're talking 0-100km/h coming in 3.6 seconds. That also matches the RS 6 Avant and it's a tenth of a second faster than the Audi R8 V10 RWD supercar, (and also the previous-gen RS 7 Sportback Performance) and this is a large, four-door, five-seater.

Compared to the previous generation RS 7 Sportback Performance the power is down by 4kW, but torque is up by a whopping 100Nm. Give me torque over power any day.

Shifting gears is an eight-speed automatic transmission, sending the drive to all four wheels.

The RC 350 is motivated by a lusty 3.5-litre naturally aspirated V6 petrol engine that produces 232kW of power at 6600rpm and 380Nm of torque from 4800-4900rpm.

For reference, the RC 300 uses a 2.0-litre turbo-petrol four-cylinder unit that develops 180kW at 5800rpm and 350Nm from 1650-4400rpm.

Either way, these outputs are exclusively sent to the rear wheels via a well-sorted eight-speed torque converter automatic transmission with paddle-shifters.

This combination helps the RC350 sprint from a standstill to 100km/h in about 6.1 seconds while on the way to its electronically limited top speed of 230km/h.

This is a large, all-wheel drive car with a 600 horsepower V8, but it also has a mild hybrid system in this new generation, which will switch the engine off at let the car coast down hills or at speeds under 22km/h.

Audi says this can save up to 0.8L/100km in real-life driving. That's great news, but consumption is still fairly high with Audi saying that after a combination of open and urban roads the RS 7 Sportback will have used 11.6L/100km.

The RC350’s fuel consumption on the combined-cycle test (ADR 81/02) is 9.1 litres per 100 kilometres, while its carbon-dioxide emissions are 212 grams per kilometre, but both claims are a little keen.

In our real-world testing, we averaged 12.2L/100km, which is far cry from the above, given our result came from 180km of driving that was heavily skewed towards highway stints over city traffic.

For reference, the RC 350’s 66L fuel tank takes 95 RON premium petrol at minimum.

I've never met an RS model that hasn't been great to drive – these cars are way more than just tough body kits and big wheels. The engineering which separates the RS 7 Sportback from the A7 makes them more distant cousins than siblings.

As I mentioned before the RS 7 Sportback and RS 6 share more than the same twin-turbo V8, there are also the giant brakes in form of 420mm discs at the front with 10 piston calipers and 370mm discs at the rear.

The optional carbon ceramic brakes are the largest ever to be fitted to a production vehicle at 440mm at the front and 370mm at the rear, saving 34kg in mass over the steel brakes.

Now standard for the first time is Audi's Dynamic Package, which adds dynamic steering (a variable ratio) paired with all-wheel steering, a sport differential, and a 280km/h top speed.

Coming standard is adaptive air suspension and for $2850 you can option the Dynamic Ride Control suspension, which is a hydraulically activated adaptive damper system 

At the Australian launch, Audi supplied two RS 7 Sportbacks: one with the air suspension and the other with not only the Dynamic Ride Control system, but also the RS Dynamic Package Plus which adds the ceramic brakes and increases the top speed to 305km/h – this was the car I started off in.

I'm going to say right away that you don't need ceramic brakes for regular road use. Sure it means you can tell people that you have the biggest brakes in the world and they save you almost 35 kilos in weight, and, yes, they're resistant to fading, but they're expensive to replace and the steel ones are incredibly good.

I also feel the Dynamic Ride Control sports suspension isn't necessary in a car like the RS 7 Sportback. This is a Grand Tourer designed to eat up hundreds of miles at lightspeed in comfort.

So, while I found the first RS 7 Sportback with the big brakes and sports suspension sharper and firmer than the standard car, it didn't seem to fit with this vehicle's intent.

The regular RS 7 Sportback still accelerated with the same brutal force and roared at the scenery flashing past. It still handled through the tight corners superbly with excellent turn in, mind-boggling traction and grip, and excellent body control, but all in far more comfort.

This is the point – we covered hundreds of miles at the Australian launch of the RS 7 Sportback in a range of RS models, and sports suspension can go from great to gruelling on Aussie roads with their coarse-chip bitumen and potholes. The RS 7 Sportback, with its air suspension, not only made driving far more comfortable, but easier, too.

The RC350 F Sport is actually pretty good to drive – so long as you understand what it’s about.

Think of it more as a comfortable cruiser than a sports car and you’ll forgive it for some of its shortcomings. Yep, it is that relaxing to drive.

While the F Sport’s suspension (independent double-wishbone front and multi-link rear axles with adaptive dampers) does have a sports tune, it still serves up a comfortable ride on most surfaces.

Naturally you can play with the five drive modes (Eco, Normal, S, S+ and Custom) on hand to increase its stiffness and therefore improve handling, but the difference between soft and ‘hard’ is negligible, so don’t bother.

Either way, the F Sport does have a noticeable habit of picking up sharper road edges, such as nasty potholes, and it's particularly prevalent at the rear. That said, it doesn’t detract from its luxuriousness all that much.

Where the sportiness really comes to the fore, though, is via the F Sport’s electric power steering system, which has a variable ratio.

As well-weighted as this set-up is as standard, you’ll find it hard to forget how sharp it is on turn-in. Among several factors at play, the obvious one is the F Sport’s rear-wheel steering system, which is better executed than most.

This technology turns the front wheels in the opposite direction to the rears at lower speeds but in the same orientation at higher velocities.

The result of the former? A mid-size coupe that feels like it has a short wheelbase, with the improved manoeuvrability especially noticeable in car parks. Conversely, the latter lends itself to greater stability when you need it.

And it’s a good thing it is the way it is, because the RC 350 F Sport has a kerb weight of 1740kg, which is not exactly sports-car light. This heft is a felt when cornering hard, even though body control is pretty strong overall.

Handling performance is also enhanced by the rear Torsen limited-slip differential, which helps improve grip upon corner exit, at which point the RC 350 gets to show off its straight-line abilities.

The V6 engine is buttery-smooth, but you really need to stick the boot in to fully enjoy it, with it only really starting to come alive when engine speeds are above 3000rpm.

That said, it’s easy to appreciate this character trait around town, where the RC 350 is truly unfazed. Take it onto the open road, though, and acceleration is more than pleasing.

The automatic transmission is a great dancing partner here, serving up delightfully smooth gear changes. It’s also surprisingly responsive, perhaps too responsive, as it can be quite fussy in city traffic, shuffling up and down ratios in quick succession.

Biggest gripe, however, is the digitally enhanced sound the RC 350 produces. Sitting inside, the noise being pumped in is satisfying, but you can’t help but acknowledge the aural deception at play.

Neither ANCAP nor Euro NCAP have issued a safety rating for the RC range, although the mechanically related IS line-up received the maximum five stars in 2016.

Advanced driver-assist systems in the RC 350 include autonomous emergency braking (with pedestrian detection), lane-keep assist, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control, a (low-resolution) reversing camera and front and rear parking sensors. Yep, the only major thing missing here is steering assist.

Other standard safety equipment includes eight airbags (dual front, side, curtain and knee), anti-lock brakes (ABS), electronic brakeforce distribution (EBD), brake assist (BA) and the usual electronic stability and traction control systems.

The RS 7 Sportback is covered by Audi's three-year, unlimited kilometre warranty which not only falls behind in duration compared to mainstream brands but also its direct rival Mercedes-Benz which now has five-year, unlimited kilometre coverage. 

Service intervals are every 12 months or 15,000km with a three-year plan costing $2380 and a five-year plan for $3910.

As with all Lexus models in Australia, the RC 350 comes with a four-year/100,000km warranty and four years of roadside assistance. Both offers are a year behind that of fellow premium brands Mercedes-Benz and Genesis.

The RC 350’s service intervals are every 12 months or 15,000km, whichever comes first. A three-year/45,000km capped-price servicing plan is available, costing $495 per visit, which is not too bad at all.
