Audi S4 vs Genesis G70

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.  

The updated Genesis G70 3.3T Sport Luxury is beautiful to look at and drive. It features premium features, trims and great power but the cabin is tight on space. Which makes it a little awkward to use, so this will suit a small family best or families where this may not be the primary mover. That said, I love the after-care program and it suited my small family of three, so it gets an 8.0/10 from us. 

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 G70 sedan is absolutely gorgeous to look at and the our test vehicle's 'Kawah Blue' paintwork makes the crisp pleating across the body stand out.

The G70 has a muscular stance, much like its BMW rival, but the rear is softer in its shaping.

The front looks sophisticated with the wide-set LED lights and black air-intake vents. The sporty 19-inch alloy wheels and red calipers behind them hint at what the powerful V6 engine can do.

The interior looks high-end with our test vehicle’s white quilted Nappa leather upholstery and a soft-touch black headliner. The dashboard looks solid and robust but the slick looking 10.25-inch touchscreen multimedia system and digital climate control panel elevate the overall design. 

The only thing I didn’t like about the design was the ambient lighting. It’s limited to two panels on the roof and is a little distracting when you drive at night. I think if it was scattered more throughout the cabin, it would be less intrusive.

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 practicality is hurt a little by the space available for passengers. The front row benefits the most when it comes to head- and legroom but if you’re ferrying passengers in the back seat, you’ll have to scoot your seat forward to accommodate them.

Especially if they’re tall because my knees brush the back of the driver’s seat when it’s in my driving position and I’m only 168cm tall!

The individual storage options throughout the car are okay for the class with the front enjoying a small middle console and glove box, two cupholders and two small drink bottle holders in each door.

The rear gets map pockets, two cupholders in a fold down armrest and two very small storage bins in the doors.

The other amenities are great in both rows and a high-level of comfort will be found for adults with the heat and ventilation functions on the front seats and the heat function on the rear outboard seats.

However, the width of the rear seat and the tall transmission tunnel means the middle seat should be strictly reserved for a kid. Think of the G70 as more of a four-seater if you have adults to carry.

The boot has a 330-litre capacity and it’s not too hard to reach to the very back if items roll that way. The back seat has a 60/40 split and there is a temporary spare tyre underneath the floor. 

In terms of technology, you get a USB-A and USB-C port up front, as well as, a 12-volt socket and wireless charging pad to choose from. Rear passengers get two USB-C ports and the boot features another 12-volt outlet.

The 10.25-inch multimedia system looks great and is easy to use with a responsive touchscreen. It also has built-in satellite navigation, wired Apple CarPlay and Android Auto and the system now features over-the-air updates and Genesis Connected Services functionality.

The digital climate panel is responsive and very simple to operate, which is handy when on the go. The 12.3-inch digital instrument cluster is semi-customisable and it’s handy that the 8.0-inch coloured head-up display pulls through satellite navigation directions and traffic sign information. 

The G70 3.3T Sport Luxury sedan on test here is priced at $88,000, before on-road costs, which is $7000 more expensive than the 2.0T Shooting Brake version. That positions it right in the middle of its nearest competitors and you get some fab features included. 

The premium items include electric front seats with heat and ventilation functions, heated rear outboard seats, Nappa leather upholstery and other leather trims, a sunroof, a heated leather-wrapped steering wheel and a premium 17-speaker Lexicon by Harman sound system.

The update sees the G70 now have an intelligent speed limit assist feature, the 'Genesis Connected Services' app and over the air updates to its software.

Other standard features include keyless entry, keyless start, remote start from the key fob, a powered tailgate, 19-inch alloy wheels, a temporary spare wheel, dual-zone climate control and extendable sun visors.

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. 

The G70 3.3T Sport Luxury sedan has a 3.3-litre V6 turbo-petrol engine with a maximum power output of 274kW and 510Nm of torque. The G70 sedan is a rear-wheel drive and features an eight-speed auto transmission.  

The V6 engine responds eagerly, being able to do a 0-100km/h sprint time in just 4.7-seconds. Suffice it to say it’s fun to drive.

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.

The compromise for getting all of the power is that she’s a thirsty gal and the official combined cycle fuel consumption figure is 10.4L/100km and my real-world usage came to 10.6L/100km.

However, that’s after mostly doing open-roading – expect the fuel usage to be higher in an urban setting.

Based on the combined cycle and the 60L fuel tank, expect a driving range of around 577km on average. Which means you’ll be filling up more on a longer journey than more efficient sedans.

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.

The G70 sedan is a lovely car to drive with graceful handling and a good well of power to dip into.

That oomph is there when you need it and it’s as easy to drive in the city as it is on the open-road.

The responsive steering makes the G70 sedan feel nimble and well-balanced in turns, even when you accelerate out of a hair-pin corner.

The suspension is on the firm side and that can lead to a few grunts when you hit bigger bumps but the ride is not unpleasant, even for back-seaters. 

The cabin is generally quiet but you can get road/wind noise at higher speeds. It’s not enough to intrude on chatting but you don’t forget it’s there, either.

The G70 sedan is easy to park because it has an outstanding 11m turning circle. The 360-degree camera system is clear and the front and rear parking sensors make light work of a tight car park.

The Genesis G70 has a great suite of safety features and it’s almost a case of what doesn’t it have.

But a real highlight is the blind-spot view monitor which pops a video feed of your blind spot onto your instrument cluster. Very handy to have in a city setting!

The G70 has a maximum five-star ANCAP safety rating from testing done in 2018, with the update now featuring 10 airbags, which is fantastic for the class.

Other standard safety features include blind-spot monitoring, blind-spot collision avoidance assist, driver attention warning, forward collision warning, lane keeping aid, lane departure alert, rear cross-traffic alert, rear occupant alert, adaptive cruise control with stop and go function and a tyre pressure monitoring system.  

A clear 360-degree camera system as well as front and rear parking sensors also come standard.

The G70 has AEB (operational from 10–180km/h) with pedestrian and cyclist detection.

There are ISOFIX child seat mounts on the rear outboard seats and three top tether anchor points but only two child seats will fit. Front passenger comfort may be compromised for front occupants when a 0-4 rearward facing child seat is installed.

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.

The Genesis after-purchase program is hard to beat and such a treat because you get five years or up to 50,000km complimentary servicing with the G70. How good is that? 

The G70 also comes with a five-year/unlimited km warranty and the servicing intervals are every at 12-months or 10,000km, whichever occurs first. The interval could be annoying if you travel a lot but any annoyance will be softened by the fact that the services are free.
