Tesla Model S vs Audi RS4

What's the difference?

I spoke to a friend who bought a Model S before one had even hit the ground here in Australia. He chuckled when I told him how much this car cost but then said something I'd already suspected. "My mates who own a P100D would never drop that kind of money on a normal car. Buying a Tesla is like buying shares in the company, you're buying into the future."

And that's kind of the point. A $300,000 Audi RS7 (fully-loaded, obviously) is a bit slower in a straight line, looks just as good, is extremely well-built and emits noises that make people like me go as weak at the knees (just as the Model S' acceleration does). And would probably win a 10 lap race with the Tesla around Mount Panorama.

The Tesla is the future of cars. It may still be decades before the internal combustion engine is gone, but Tesla buyers are getting the jump, and today the Model S is the best car in which to make that leap.

What a way to send off this generation of Audi RS4 and RS5. The extra focus courtesy of those trick coil overs and drama from the exhaust plus the sharper gear changes deliver the best Audi has done with these RS products. 

There are some compromises, with the suspension favouring outright control over low-speed comfort. It’s also true that the current BMW’s M3 and M4 are more impressive, but when the products are nearly seven years fresher than Audi’s, what do you expect? 

Plus, those looking for a more restrained and polite fast executive sedan (or wagon) will gel with the Audi’s sophistication. There aren’t many of these Competition Plus RS4 and RS5s coming to Australia and they are impressive visually and from behind the wheel. It’s a fitting way to send off the current generations.

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

The Model S is definitely the looker of the three Tesla models on sale (the Model 3 might be some way from release, but you can reserve one and it's... weird-looking). With a slinky, Jaguar XF/Audi A7 roofline and low-slung stance, it looks the business. Like the X, the detailing of the car's surfacing and panel gaps aren't where other $200,000+ cars are, but it has improved a lot over the last couple of years.

The cabin has improved even more than the exterior.

The styling is quite sparse, really. Teslas look like computer renders in real life, especially in white, with little in the way of jewellery or detailed design elements. And that's probably the idea. It's a cleaner design than when first launched, with a simpler, flatter snout that brings out the headlights better.

The cabin has improved even more than the exterior. It's still the same minimalist design, but it fits together much more tightly than it used to. The 17.0-inch portrait screen is still there in its central but skewed-to-the-driver position and is now up to version 8. It's an impressive interface, covering off the vast majority of functions in the car, and is mostly easy to use. The responsiveness is key to its usability. If it was underpowered, you'd quickly start demanding real buttons.

The RS4 Avant’s 'Progressive Red' metallic helps the black milled 20-inch alloy wheels pop. Its stance is hugely purposeful with wheels tucked right up in the blistered arches courtesy of the lowered ride height — it's how the Avant would have looked in a design sketch.

The visual bulk of the long-roofed RS4 gives it the sort of proportions motoring journalists love to wax lyrical about, even if plenty of buyers still prefer coupes or lifted SUVs. 

The RS5's more flowing, elegant lines match well with the Navarra Blue paint work, silver-accented wheels and conventional leather-appointed seats within. 

Both cars have effectively identical front cabins reflecting Audi’s classy and sleek design language. The integration of technology is pretty good and the RS4’s additional red styling pack really makes it feel sporty within.

The Model S is a rare car in this class in that it has an almost completely flat floor, meaning rear seat passengers don't have to negotiate a transmission tunnel. The two motors run physically independently of each other so there's no crankshaft to get in the way.

The floor is thicker than a normal car, it's like a big skateboard underneath. That means your knees are up higher, which might cause numb bum on a long trip. The rear seats are comfortable enough, but middle seat occupants might feel like the outboard passengers are falling into them.

With all that torque, when you do load it up, the extra kilos barely make a dent on the performance.

The view out isn't too bad given the rising window line, and if you've got the big two piece sunroof (without cover, irritatingly... ), it's quite airy out back. And hot (with the sunroof), but you do get rear air-con vents.

The boot is an eminently sensible 744 litres with the seats up and 1795 with the seats down, although the floor doesn't fold flat. While it's a big boot, it's relatively shallow so your suitcases go in on their sides. Up in the front boot (or froot) there's another 150 litres, so you can pack a lot in to the Model S. And with all that torque, when you do load it up, the extra kilos barely make a dent on the performance.

The RS4's cabin is excellent, with a good mix of physical buttons and responsive touchscreens for control. There’s enough storage space for this kind of vehicle, with good door bins and well-sized cupholders in the centre as well as USB-C and -A charge points. 

Audi’s multimedia system is friendly though the large touch targets and dark background aren’t as crisp as those fitted to the latest rivals. The screen isn't as big, either, measuring 10.1 inches for the multimedia item. The RS4 supports wireless Apple CarPlay and Android Auto.

That said, Audi’s 12.3-inch digital driver’s display with bright and poppy mapping software and generous customisation remains right at the head of the pack. 

There is a panel of switches below the touchscreen for climate control, physical selection of the five-or-so drive modes and a collection of helpful buttons on the perfectly-shaped and sized leather-appointed steering wheel.

It lacks F1 or DTM wow-factor compared to the C63 and M3 with their easy-access driver mode buttons and toggles on the steering wheel but the RS4's restrained looks will resonate with those that prefer a bit more elegance inside. 

Neither the RS4 nor RS5's back seats are designed for those over about 175cm. The RS4’s roof is a little higher so it is good enough for most adults but the RS5’s sloping profile compromises things. It has two individual buckets compared to the RS4’s three-wide bench. 

Rear seat passengers get air vents, an individual climate zone, bottle holders in the doors, USB charge points and ISOFIX attachments for the outboard seats, with matching top tethers in the seat backs.

The Audi RS4’s boot is a generous 505L with under floor storage and a netted area on the driver’s side. Folding the 40/20/40 split-fold bench increases space to 1495L. That said, the RS5’s 465L is still very good, though it is not quite as practical in the real world. 

Being fitted with roof rails makes for sleek integration of roof racks for the RS4 to slip roof pods, bike racks or whatever else you might choose to take on a trip away.

You'd expect the RS5 to be more popular given how uncool wagons are these days but Audi's whole thing is wagons — or Avants, for the initiated — so it makes sense that the RS4 Avant outsells the RS5 Sportback about two-to-one.

For the RS4 Avant’s basic asking price of $165,015, before on-road costs, you get luxury features such as LED headlights, an RS design package, Nappa leather upholstery, power-adjust seats, a Bang & Olufsen 19-speaker sound system and metallic paint on top of the significant changes to the RS4’s chassis and zingy 331kW V6. 

The RS5 is a little dearer, reflecting the addition of Matrix LED headlights that aren’t available on the wagon.

But we have the 'Competition Plus Pack', which is a $13,990 indulgence that swaps adaptive dampers for Audi’s 'RS Sport Suspension' coil over package with manual rebound and compression adjustment and height adjustment.

The cars sit 10mm lower than a normal RS4 but you can go to a dealer to move the ride height up or down from there. 

That’s not it, though. You also get a louder exhaust system with matte black pipes, fixed-ratio steering system, a retuned eight-speed automatic with more aggressive shifts, different rear differential programming, black exterior badging, 2.0kg lighter 20-inch Audi Sport wheels (in silver or black), special LED entrance lights and your speed limiter raised to 290km/h.

The 'Navarra Blue' RS5 pictured is a ‘basic’ Competition Plus. You can go further, as done with the RS4 Avant with its manual-adjust bucket seats ($1300), 'Interior Design Pack' in red ($3400), matte carbon exterior pack ($6300) and carbon trim, bringing its total cost to $191,405, before on-road costs. 

That makes the RS4 and RS5 the most affordable in their competitor set, below a BMW M3 Competition xDrive Touring ($183,500) and Mercedes-AMG C63 S E Performance hybrid, which is $187,900, before on-road costs.

The P100D ships with two electric motors fed by a huge battery pack which triples as the bulk of the chassis and a super-strong crash structure. It's also shared with the Model X SUV.

Combined power output is 568kW with more of it out the back rather than up front. Torque is quoted at 1000Nm, but it's likely more than that. Claimed 0-100km/h time is a mildly unbelievable 2.7 seconds, with a further two-tenths to be shaved off when you press and hold Ludicrous Mode and accept a warning that you'll wear the car out faster if you use it.

With 'Ludicrous Mode' comes not just software but a higher capacity fuse that allows more power to be drawn from the batteries for longer to provide the searing acceleration.

Audi’s 2.9-litre twin-turbo petrol V6 has seen plenty of use across performance products from Audi and Porsche, including the Macan S and Audi S6. 

In the RS4 and RS5 Competition Plus, it develops the same 331kW (at 5700-6700rpm) and 600Nm (at 1900-5000rpm) as the regular car. This makes it an extremely flexible engine that delivers predictable punch anywhere in the power band.

That said, it lacks the explosive character of BMW’s twin-turbo inline six — the figures are only 15kW and 50Nm higher on paper yet the M3’s response is that much more ferocious. 

Audi’s RS division has tried to capture a bit more emotion, retuning the eight-speed torque converter automatic transmission for crisper shifts. This also benefits the RS4’s 0-100km/h sprint time, which falls two tenths to 3.9 seconds in Competition Plus guise. 

The V6 breathes a little easier, too, with a different exhaust. Audi says the extra sound is down to 8.0kg less sound deadening in the car.

There’s more resonance at idle that does feel tiring sitting in traffic idling but the trade-off is a brawny mid-range baritone that develops into a shrill bark approaching the redline.

Zippo. Obviously with the new rules for Tesla Superchargers, it's not as cheap to own and run a Tesla as it was before (from January 2017, all new orders don't get free juice after the first 400kWh), but if you charge it at home (and can get away with it), it'll probably be cheaper than using Tesla's chargers. If you look, there's a company offering $1 per day charging for electric cars.

If I'd charged the car to 100 percent rather than the 80 percent recommended by Tesla for most charges (past that mark, the charge rate drops and the software has to slow to a trickle, doling out the electrons to the different cells), I would have managed just over 400km on the charge.

The Audi RS4 wagon is rated to use 9.5L/100km in ADR combined cycle (urban/extra-urban) consumption testing while the slipperier RS5 returns 9.4L/100km in the same test. 

We weren’t able to run accurate or particularly relevant fuel figures on the event but the trip computers showed around 12L/100km in both RS4 and RS5. 

While these numbers are high compared to your average passenger car, the Audi is more efficient than BMW's rivals, and gets remarkably close to the hybrid C63 in the real world.

The fuel tank is quite small for this kind of vehicle at 58 litres. That limits the RS4’s theoretical driving range to 611km. 

Unsurprisingly, the Audi RS4 and RS5 require 98 RON premium unleaded petrol. 

The first time I drove a Model S, I enjoyed the acceleration and the silence of the electric motor (this was back in the Dark Ages when even the P90 only had one motor). And that has remained, with the air suspension providing a firm but comfortable ride despite the P100D's 21-inch rims and very low profile tyres. Electric motoring in any electric car is addictive.

Much progress has been made (yes, I'm getting to the acceleration, stay with me) in the way it drives. The earlier cars felt too computer gamey, with little feel through the wheel or the seat of your pants. The steering is better, especially in Sport mode, but not a lot gets through the air suspension, so it takes a while to build confidence in the chassis.

One passenger became quite emotional, almost crying. And not just because they were stuck in a car with me.

On the freeway (look, you can read ahead if you must) it's amazingly quiet, with just a bit of a rustling around the mirrors. Well, of course it's quiet, it's electric. For chassis and NVH (noise, vibration and harshness) squashers, not having the marvellous engine noise means much harder work to dull the other noises you just don't hear when there's an internal combustion engine.

And there's the acceleration. As the driver, you obviously know it's quick. Mash the throttle and the response is instant, the horizon closing in on you like you're attached by a very stretched and immensely strong bungee strap that's just been released. The way cars disappear in your rear vision mirror is hilarious.

It's more fun as a passenger, though. The Model X elicited whooping and laughing, but the P100D's extra 0.6s-worth of acceleration over the P90D, delivered with a truckload more G-force, equals silence. One woman said she was glad I'd caught her before dinner rather than after, before bursting forth with a range of expletives. One passenger became quite emotional, almost crying. And not just because they were stuck in a car with me.

The time allocated to driving the RS4 Avant Competition Plus was fairly limited and we were sadly unable to sample how the highly adjustable coil over suspension performed where it makes most sense — on the racetrack. 

Still, winding country roads between Sydney and the Southern Highlands served up some challenges, demonstrating how the Competition Plus pack changes the character of the RS4 and RS5. 

The only real negative is comfort, specifically over those horrible plastic speed bumps that litter shopping centre car parks. With adaptive dampers, carmakers can set programs for these kinds of obstacles to soften and stiffen the clever shocks at just the right time. Not so the Competition Plus pack cars, which ride these bumps harshly.

That about does it, though, and everything thing else is a net benefit. The steering system addresses some criticism of the earlier RS4s. Further than a retune, the Competition Plus gets a new rack, that is non-progressive with a fixed ratio of 15:1 (instead of 13.3:1) and 2.4 turns lock-to-lock. The reactions to each input feel a hint more faithful. 

When above 40km/h the coil overs come into their own. Even though the RS4 rides firmly it doesn’t constantly jiggle over small bumps. Over sharp-edged hits, the suspension rounds the hits off so, while you feel them, there’s a sense of control and sophistication. 

Having speed limits to contend with means it is essentially impossible to find the limits of grip of the 275/30R20 Continental SportContact 6 tyres on the road and there isn’t much body roll, either.

The RS4 is still rewarding, though, getting up on its toes just enough through a series of bends to feel engaging. It gives an impression of being quite light and at 1820kg it is now considered featherweight next to rivals.

The RS4's Quattro all-wheel drive system favours the rear wheels when driving normally (60 per cent rear) and can send up to 85 per cent of the drive to the back axle. 

The tweaked electronically-controlled rear limited-slip differential amplifies the throttle steer-ability of the RS4, giving you the confidence to squeeze the gas on exit. 

It helps that the Competition Plus bucket seats are a little thinner and set closer to the floor giving you more feedback. This is the key differentiator between the RS4 and RS5 we drove — the buckets make the car feel alive. 

Strong brakes are made up of 375mm front rotors clamped by six-piston calipers. Optional carbon ceramic brakes with larger 400mm front rotors help save 6.5kg and, if you plan to use the RS4 on track, are a smart buy along with a set of Pirelli P Zero Corsa semi slick tyres ($850). 

Really, though, neither the RS4 nor RS5 are the perfect car for the track. They are plenty capable and fast on the road with just enough fun, reward and character thrown in to keep you coming back for more.

The Audi A4 range was rated a maximum five stars in ANCAP safety testing in 2021, with the rating now considered expired. The stamp also only applied to four-cylinder models — so not the RS4 we drove. 

It has lots of safety equipment, including eight airbags (dual frontal, side chest, front and rear side head curtains), autonomous emergency braking (AEB) functional up to 250km/h with pedestrian detection, front and rear cross-traffic alert, lane-keep assist, blind-spot monitoring, safe exist warning and tyre pressure monitoring.

Adaptive cruise control with lane-trace assist makes it an easy car to use on the motorway. The systems are well integrated and easy to switch on and off as you like. 

Tesla offers a four-year/80,000km warranty with a parallel eight year/unlimited kilometre warranty for the battery and drive units. Roadside assist applies for the four year warranty period.

Tesla offers two maintenance plans, three and four years in length. The three year plan costs $2100 and the four year $3175. Paying for the services individually over the same period will cost $2300 and $3425 respectively. That includes a wheel alignment (if needed), but it isn't particularly cheap when compared with 'normal' luxury cars.

Your first 400kW/h of recharging is free using Tesla's supercharger network, so that would be four full charges from empty (which you wouldn't do, obviously), or about 1600km worth. After that, it's 35c per kWh or $35 for a full charge.

Audi covers the RS4 and RS5 with a five-year/unlimited kilometre warranty which is now the expected norm across the premium part of the market. 

A five-year service plan can be pre-purchased, costing $3630 for both models with maintenance due annually or every 15,000km. 

After the five-year warranty period, owners can choose to extend the service packaging and warranty for two extra years at a cost of $4260. This can be done twice, extending the warranty up to nine years.
