Audi S4 vs Toyota Prius V

What's the difference?

The S4 and S5 range continues to represent a great formula for performance you can live with every day. They're arguably the sweetest balance Audi produces, actually. All come fantastically equipped, with cabins that feel truly special, and we’re lucky they can be had in a choice of five bodystyles.  

No, the Prius V isn’t exciting. But it does what it’s designed to do - move families in decent comfort without using much fuel. And if that’s what gets your (hybrid) motor running, then you really ought to take a closer look.

The S4 sedan and Avant have scored the bulk of design updates, with all new and recontoured side panels including the sedan’s C-pillar matching what was applied to the A4 earlier this year. 

This is paired with new front and rear facias and lighting for a subtle but extensive rework of the fifth-generation S4’s conservative look. 

The S5 Sportback, Coupe and Cabriolet get S5-specific new lighting and facias, but no sheetmetal changes. As before, the Coupe and Cabriolet ride on a 60mm shorter wheelbase than the Sportback, sedan and Avant.

The S5s also get Matrix LED headlights as standard which do a neat animated sequence when you unlock the car. 

Other visual hallmarks include new S4-specific 19-inch wheels, with S5 stepping up to its own unique 20-inch wheel. The six-piston front brake calipers are appropriately painted red, and there’s S-specific adaptive dampers under there too. All variants aside from the Cabriolet get a lip spoiler on the rear.

On the inside, there’s a new centre console and bigger 10.1-inch multimedia screen, while the Audi Virtual Cockpit driver instrument display now offers a hockey stick-style rev counter in additional to traditional dial layouts.

The world was a different place when the Toyota Prius V came out. Back then, the iPhone 4s was at the cutting-edge in phone design, Gangnam Style was smashing it on the charts, and car design was in a very different place.

There are some signature Prius elements, with a swept, aerodynamic looking roofline and sleek front-end styling. The facelift that was applied to the Prius V in 2015 saw sharper lines and more aggression, but it arguably doesn’t have a lot of aesthetic appeal given the way Toyota has evolved its design since then.

It isn’t a traditional people-mover, because it has regular doors at the back rather than sliding doors to allow simple access to the third-row seats. It’s more like a hatchback that’s been stung by a bee, looking a bit bloated. But as one pint-sized tester put it this week, it’s one very big little car.

The inside is a bit of a marvel in terms of space management. This car measures just 25mm longer than a Corolla sedan (4645mm long), and it's only 1775mm wide (the same as a Corolla sedan) and 1590mm tall, because it needs a bit more room to fit seven people in. And it can.

The biggest practicality change among the five S4 and S5 variants is their upgrade to the latest version of Audi’s MMI multimedia system, which steps up to a 10.1-inch touchscreen and drops the scroll wheel from the centre console.

It also boasts ten times the computing power of the version it replaces and uses this and an on-board sim card to access Google Earth maps for navigation and Audi Connect Plus that offers driver information such as fuel prices and parking information as well as point of interest search and weather information, plus the ability to make emergency calls and seek roadside assistance.

There’s also a wireless phone charger, but using Apple CarPlay will still require a cord as per Android Auto.

I only drove the S4 Avant and S5 Sportback at their media launch, which are clearly the most practical of the five, but from our experience with the previous versions, each looks after its occupants well in terms of space and storage. Back seat accommodation is clearly not a priority in the Coupe and Cabriolet, but there’s three other variants if that’s what you’re looking for. 

The Cabriolet can open its automatic folding soft top within 15 seconds, at speeds of up to 50 km/h.

The cabin of the Prius V highlights the notion of versatility. There are two rows of seats at the back, with the middle row sliding and folding to allow easy third-row access. And I mean easy - even me, a 183cm-tall human - can clamber into the back seats without too much in the way of old-man noises.

The space in the back row is limited, though, particularly for knee room and foot space. It is best left for children, then. But the second row has three individually slide-able seats, meaning if you really need to fit seven adults in, you theoretically could.

That second row is nicely useable. The fact the seats are sculpted individually means they feel made for a proper family getaway, and even with them set as far forward as they can go (to allow maximum legroom in the third row) I could sit in the outboard seats without much discomfort. The sun-blinds that are built into the back doors are a really welcome touch for parents and adults alike.

What isn’t so great is the lack of rear air-vents - there aren’t any face-level vents in either the second or third rows, meaning things could get stuffy on a hot day.

But the practicality side of things is reasonably well sorted, with useable cup holders in the rear wheel arch moulds, plus there’s a 12-volt outlet in the third row, too. The middle row has bottle holders in the doors, and there are map pockets in the front seatbacks. 

Up front there is more smart storage; a pair (yep, two) of gloveboxes adorns the dashboard, and there’s a pop-out cupholder on the passenger side, too. Two more cupholders grace the centre console (which itself is very shallow, because the hybrid batteries sit inside it), plus a small storage box - presumably for your keys to sit. A small shelf sits at the bottom of the centre stack, and that’s where you’ll find a USB port to connect to the media screen above.

That 6.1-inch touchscreen is fine, but pretty ancient. It has some small menu buttons, won’t allow you to input phone numbers or connect to Bluetooth when the car is moving, and you (or your fellow front passenger) can’t manually enter sat nav details when you’re driving. There is voice control, but it’s painful. Forget Apple CarPlay and Android Auto, too - neither is available in the Prius V. 

While the boot space is pretty limited with seven seats in place - Toyota claims 180 litres of capacity in that configuration - there’s still enough room for a suitcase or two. 

But with five seats in play it makes quite a bit more sense, more easily fitting family things like prams with its 485L of cargo capacity. And remember, there are no batteries under the boot floor eating into space, and you get a space-saver spare wheel as well.

Not only is the Prius V the most affordable seven-seat hybrid car on the market, it’s also the cheapest Toyota with seven seats. 

It undercuts the Tarago, Kluger and Land Cruiser Prado by a decent margin, with pricing starting at $37,590 for the base grade model and stretching to $45,380 for the top-of-two-tier i-Tech flagship. Should you bother spending up on that version? In short, no.

That’s because the regular Prius V has a pretty strong standard equipment list. Push-button start, keyless entry, sat nav with SUNA live traffic updates, a reversing camera, climate control and a head-up display are all standard. You also get 16-inch alloy wheels, which have a set of plastic wheel covers over the top (great for kerb touch-parkers).

The i-Tech sees the addition of Bi-LED headlights with auto-levelling (as opposed to the halogens with LED daytime running lights you see on the base model), plus fake leather seats (not cloth), heated front seats, a dual-pane panoramic glass roof (which doesn’t open), an auto-dimming rear-view mirror, and a semi-automated parking system. 

Plus, whether you choose the entry grade or the high-spec, you get Toyota’s 'Safety Sense+' system - read the details in the safety section below.

Colour options for the Prius V are quite broad. There are nine rather sedate hues to choose from, with eight of them being 'premium colours' that attract an additional cost ($450). 

And, as with most Toyota models, there is a range of additional factory-backed accessories that you can choose, such as a bonnet protector, boot scuff guard and even door handle protective film (to stop rings from scratching them up), but things like roof racks/roof rails or a roof pod are unavailable.

Audi has taken an ‘if it ain’t broke’ approach with the mechanicals, with all S4 and S5 models unchanged with this update. So the centrepiece continues to be the single-turbocharged 3.0-litre V6 that produces 260kW and 500Nm, with the latter available from a broad 1370-4500rpm.

The rest of the drivetrain is also unchanged, with the venerable but excellent ZF eight-speed torque converter auto paired with the Quattro all-wheel drive system that can send up to 85 per cent of drive to the rear wheels. 

Powering the Prius V is a 1.8-litre four-cylinder engine, which uses a CVT auto and combines with a lithium-ion battery pack and two electric motors. It’s what’s known as a series parallel hybrid set-up.

The system can allow the car to run using both the battery and engine, or just the battery, or have the regenerative braking system feed the battery pack more juice. That tech isn’t necessarily cutting edge today, but it was when the car launched (waaaaay back in 2012).

The engine can produce 100kW of power and 142Nm of torque. The electric motor can produce 73kW on its own, but the maximum combined power output is still 100kW.

Official combined fuel figures range from 8.6L1/00km for the S4 sedan to 8.8L/100km for the Avant, Coupe and Sportback, while the heavier Cabriolet steps up to 9.1L/100km. 

All are pretty good considering their performance potential and the size of these cars, plus the fact that they only require 95 RON Premium Unleaded fuel.

All have a 58-litre fuel tank, which should enable a range of at least 637km between fills based on the Cabriolet’s figure.

Obviously if you are considering a hybrid, you’re looking to take advantage of excellent fuel consumption. And the Prius V doesn’t disappoint.

The claimed consumption is just 4.4 litres per 100km. In the real world, you can expect to use about 5.5L/100km if you’re light on the throttle, and 6.5L/100km if you thrash it. 

You can’t skimp on the fuel when you get to the bowser, though - the Prius V insists on running using 95 RON premium unleaded.

The S4 and S5 range were already an excellent balance between everyday comfort and a genuine sporting edge, and nothing has changed with this update.

I spent time behind the wheel of the S4 Avant and S5 Sportback at their media launch, and both managed to deliver the proper Audi luxury experience over some pretty rough rural roads, while always feeling a bit more sporting than a regular A4 or A5. That’s with the Drive Select left in the default mode, but you can shift that sporting personality up a few notches (while scaling back the comfort), by selecting Dynamic mode. 

My preferred means of adjusting their personality is by simply tugging the transmission selector back to activate S mode, which livens up the engine and transmission without stiffening up the suspension. 

Across the five S4 and S5 bodystyles, there is some variance in performance potential, with the S4 sedan and S5 Coupe topping the performance chart with 0-100km/h boasts of 4.7s, with the S5 Sportback trailing them by 0.1s, the S4 Avant by a further 0.1s and the Cabriolet managing a still-fast 5.1s claim.

Another area I consider the S4 and S5s to get just right is their exhaust note. It is adaptive, but there’s nothing synthetic about it, and the generally muted and distinctly V6 burble is always there to remind you that you’re aboard a proper performance model, but not in such a way that it will annoy you, or your neighbours. Polite performance, if you will.

If you’re a car geek like me, you likely find driving as efficiently as you can fun. If so, you'll love this. You can watch the car switching between EV mode - which it will use for up to about 30km/h, but only for a couple of minutes - and hybrid power. And honestly, if you’ve never driven a hybrid you might think it sounds dumb, but being a fuel miser can be fun!

But the fun factor is pretty much limited to being a cheapskate on fuel. It really isn’t that fun to drive otherwise, but that’s not what it’s designed for.

Still, the drivetrain does a decent enough job for most families - it builds pace pretty easily, and while the refinement and power could be better, if you’re not aiming to break records on the school run, you shouldn’t be too disappointed.

The ride is mostly good, though it can be a little sharp over patchy surfaces, and the steering is decent, if a little lifeless. My biggest issue is the brake pedal response, which takes some getting used to. Sometimes it feels like it won’t stop quick enough. 

That, and the adaptive cruise control doesn’t slow to a stop on the highway - it cuts out at about 30km/h, so you’ve gotta be on your toes if the traffic starts to build up.

If you want the latest and greatest in hybrid family friendliness, you really ought to wait for the new-generation RAV4, which - admittedly - mightn’t have seven seats, but it will have a hybrid drivetrain offered. And it’ll be much more modern inside and out.

Every Prius V still carries the same maximum five-star ANCAP safety rating that it was stamped with in 2015, even though the car was actually tested in 2012.

The range is covered with the safety systems you’d expect, including electronic stability control, ABS, electronic brake distribution, plus there’s a reversing camera, too. Rear parking sensors are a dealer-fit accessory.

There was a bit of back-and-forth between myself and Toyota Australia over airbag coverage. The company stated on its public site that the car had curtain airbag coverage all the way to the third row, but no image to support that. I’ve since had it confirmed by Toyota Australia that it does definitely have third-row airbag coverage, which is a great added piece of mind element for family buyers (plus there are dual front, driver knee and front side airbags, too).

Airbags are one thing, but what about the other safety kit? Well, every Prius V has Toyota’s Safety Sense plus system, with auto emergency braking (AEB), pedestrian detection, adaptive cruise control, auto high beam lights and lane-departure warning.

Audi continues to offer a three year, unlimited kilometre warranty, which is in line with BMW but lags behind the five years offered by Mercedes-Benz these days. This also contrasts with the five year norm among mainstream brands, which is punctuated by the seven year warranties of Kia and SsangYong.  

Service intervals are a convenient 12 months/15,000km though, and the same five year ‘Audi Genuine Care Service Plan’ offers capped price servicing for the same $2950 total over five years applies to all S4 and S5 variants. This is only marginally more than the plans offered for regular petrol A4 and A5 variants, so you’re not being stung for the thoroughbred versions.

It’s cheap to run a Prius V in terms of its fuel use, and it’s cheap to run in terms of its maintenance, too. Toyota lists its charges at just $140 per visit to the dealer under the Service Advantage offer, though you’ll need to take it in every six months or 10,000km.

The warranty cover is three years or 100,000km for the car, but the hybrid battery attracts an eight-year/160,000km cover of its own.
