Audi S7 vs RAM 2500

What's the difference?

Audi’s S7 Sportback wraps style, comfort and sportiness in an appealing package that is sure to please onlookers and occupants alike.

The great engine/transmission aside, the S7 Sportback also has cutting-edge technology at a more affordable pricetag, though less-than-comfortable rear-seat space lets it down a little.

We wish the car we sampled didn’t have the all-wheel steering, as we much preferred the more neutral feel of the S6 sedan we also drove but, overall, the S7 Sportback puts forward a strong case for its existence.

If you're a grey nomad with a massive caravan searching for something to do the big lap in, or a big boater seeking an effortless weekend getaway machine, then this sort of ute makes sense. The HD series shows just how much more muscle is available, for those who genuinely need it.

But if towing or hauling to the max isn’t your priority, then the far-more dynamic – and class-leading – Ram 1500 series does everything else with much-greater aplomb.

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

Audi’s second-generation A7 has always been a bit of a looker, but Audi has taken it up another notch in the S7 Sportback.

Differentiating the S7 Sportback is a more aggressive bodykit, complete with larger air intakes up front, blacked out exterior trim, quad-exhaust tips (denoting that it’s an Audi Sport model) and large 21-inch wheels

The S7 doesn’t go too overboard with the aggressive appointments however (that’s what the top-spec RS7 Sportback, due here later this year, is for), but balances its sportiness with a stately aesthetic.

We think the S7 Sportback is stunning, especially the white exterior colour that gives it an almost Stormtrooper-like look, but even our test car, finished in Daytona Grey, while much more subtle, is still easy on the eyes.

We especially like the strong shoulder line, chiselled doors and sloping roofline of the Sportback body style that combine in profile to make the S7 look like a sprinter on the starting blocks ready to pounce.

Inside, the S7 Sportback scores all of Audi’s latest interior technology, including a 12.3-inch Virtual Cockpit instrumentation and dual-screen centre console layout.

The triple screen set-up definitely helps the S7 Sportback feel very cutting-edge from the driver’s seat, especially when you start to play around with the multimedia system that sports haptic feedback when you press the screen.

Everything is laid out in a clear, concise and easy-to-use manner, while the surfaces of the dashboard are covered in soft-touch, premium materials.

If we’re being honest, we'd probably skip the red-leather interior of our test car in favour of something a little more subdued, but to each their own.

We like the integrated air-vents that blend well into the dash, while the sea of black is broken up with some aluminium detailing and different finishes.

You can spot the HD facelift by the bi-LED headlights and bulgier bonnet, while chrome’s been replaced by black trim inside and out, including in the restyled grille, alloy wheels and side steps, for a more-modern appearance.

Both models are identical bar the badging. However, while they share a tri-link solid front axle system, the 2500 HD features coil-spring rear suspension, while the super heavy-duty 3500 HD relies on leaf springs. That’s for it to achieve maximum pulling and hauling capability.

Inside, the already-contemporary dashboard, with its 12-inch Tesla-esque portrait touchscreen, remains much the same as before, except for a few detail updates to accommodate the big new centre console, twin wireless charger housings, extra USB ports and restyled electronic instrument cluster.

Otherwise, it’s as vast as ever.

Measuring 4969mm long, 1908mm wide, 1417mm tall and with a 2928mm wheeblase, the S7 Sportback falls well and truly into the large car class.

Up front, the driver and passenger have plenty of room, while the seats and steering wheel are almost infinitely adjustable to find the perfect position.

As you can imagine though, the sloping roofline does eat into the rear-seat headroom a little.

The outboard seats offer plenty of leg- and shoulder-room, but the slanted roof prevents my six-foot-tall frame from sitting up straight comfortably.

Don’t get me wrong, the space is perfectly useable for children or even some smaller adults, but don’t expect to get any basketball players in those seats.

As for the middle seat, only children will find it comfortable due to the protruding transmission tunnel and higher-set seat.

The S7 Sportback’s boot offers at least 535 litres of space and expands to 1380L with the 40:20:40 split-fold rear seats stowed.

Being a liftback (or Sportback in Audi parlance) means the boot is much more practical than a standard sedan, and with such a large aperture, bigger items such as suitcases or golf clubs won’t be annoying to load and unload.

Bag hooks, storage tie-down points and carbo netting also feature to ensure your goods don’t roll around when the S7 Sportback is in motion.

Storage around the cabin though, could be a little better as the wireless smartphone charger takes up a fair chunk of room in the shallow central storage bin under the front armrest.

The usual storage tray found ahead of the shifter is also absent, due to the dual-screen centre console layout, but two generous cupholders and sizeable door pockets are still available up front.

Second-row passengers get access to a fold-down armrest with shallow storage tray and cupholders, as well as door pockets that can accommodate large bottles.

As with all Walkinshaw Automotive Group utes (that includes the Silverado), the Ram HD’s fit and finish seem exemplary, with an insider suggesting the quality may exceed the North American factory original.

This is no small feat. Ateco Automotive, the instigator and original importer of over 35,000 (and counting) remanufactured left-hand to right-hand-drive DS, DT and DJ full-sized utes in Australia since the first 2500 HD rolled off the Melbourne production line in 2015, says “between 400 and 500” unique engineering pieces are necessary.

Compared to the pre-facelift versions, the DJ Series II sees a switching out of the old front bench seat, which meant the earlier versions were six seaters, to shapelier individual items. Apparently, comfort and convenience are what buyers prefer, since a large centre console with armrest is now included. It’s certainly seems plush and luxurious inside.

Along with greater storage, the Ram’s electronic instrumentation is new and the multimedia system has been updated, with extra USB ports as well as twin phone chargers.

The driving position might be compromised for some by a lack of reach adjustability for the steering column (unlike in the DT 1500), and the foot-operated park brake seems like an anachronistic nowadays, but otherwise everything is easy to reach and operate – despite being scattered all about – after you’ve learned what all the buttons and switches do.

Meanwhile, the now-fixed seats can accommodate a trio of burly occupants no problems due to the sheer width of the cabin.

Included are air vents, extra USB ports, a sliding back window and storage underneath the seat cushions and within a special floor compartment.

Owners can also create a raised floor section, by tilting both cushions up and folding down two corresponding bases for a flat and even load area, with additional hidden storage within the now-covered footwells.

Overall, the Ram’s cabin balances convenience and utility quite well.

Further back, the tub length is 1938mm, width is 1687mm and 1295mm between the wheel arches and height is 511mm. This compares to the Silverado 2500’s superior corresponding figures of 2089mm/1814mm/1317mm/533mm, respectively.

A swing-away step is provided to help tub access, as well as a spray-in bedliner, strut-assisted tailgate-close and 12-pin towbar fitted as standard.

Maximum towing capacities vary from 3.5 tonnes to an unmatched eight tonnes with the correct accessories. The 2500’s payload is 785kg while the 3500 more than doubles that. And standard exhaust brakes help with braking on long descents when fully laden.

Which brings us to the heart of the matter. Muscle.

Coded as the DJ, the 2500 and even heavier-duty 3500 differ significantly compared to the DT-series 1500, and use many of the body, chassis and mechanical components from the previous-gen DS-series 2500/3500 HD. Hence the unique model code.

Only launched in North America earlier this year, the DJ Series II kicks off from $172,950 (all prices are before on-road costs) for the 2500 HD. That’s the same old retail figure as before, despite the newcomer ushering in a minor facelift, major muscle boost and more kit, although the Silverado 2500 HD is still cheaper, at about $5K less, while the old runout versions now start from under $170K driveaway.

It’s also worth keeping in mind that the Ram 3500 HD has no direct rival in Australia.

As you’d expect, many luxury features are standard, such as heated and vented front seats with driver’s side memory, leather upholstery, retractable exterior mirrors, a surround-view monitor and adaptive cruise control. Upgraded driver-assist safety systems have also been added. More on those later on.

The newly-added items include a sunroof, centre console bisecting the front seats, a 12.3-inch instrument display, wireless Apple CarPlay/Android Auto, dual smartphone chargers, eight USB ports and traffic sign recognition.

So, no more three-person front bench. And it seems the reclining rear seat has been binned for a fixed-position item.

Powering the new S7 Sportback is a 2.9-litre twin-turbocharged petrol V6, punching out 331kW/600Nm, which is paired to an eight-speed automatic transmission that sends drive to the road via Audi’s quattro all-wheel-drive system.

The result is a zero-to-100km/h acceleration time of 4.6 seconds.

Keen-eyed Audi fans might note that those are the exact same engine and outputs as the RS5 Sportback, RS5 Coupe and RS4 Avant, and they’d be right, however, Audi has added the 48-volt mild-hybrid and an electric powered compressor (EPC) to reduce turbo lag in the S7 Sportback.

It’s a similar system first employed in the SQ7 large SUV, and basically means that the EPC is spooling up the turbo at low engine speeds for better off-the-line performance.

The mild-hybrid technology no doubt helps shift the S7 Sportback’s 2040kg weight with peak power now available earlier on in the rev range (from 5700rpm), while maximum torque is available from 1900rpm.

Compared to the older car, the new S7 Sportback matches its predecessor in power, but ups torque by 50Nm despite losing the old car’s 4.0-litre twin-turbo V8 engine.

Under the now-bulgier bonnet may be the torquiest engine money can buy, at least in something that does not require a special driving license. Or pilot's licence.

Completely overhauled with a redesigned engine head, larger intake and exhaust valves, a new turbo, heavier-duty pistons, a higher-pressure fuel system and upgraded intake manifold amongst other changes, the Cummins-sourced 6.7-litre in-line six-cylinder turbo-diesel unit now delivers 313kW of power at 2800rpm and 1458Nm at 1800rpm.

Formerly making 276kW and 1152Nm, the new figures are 13 per cent and 26 per cent better than before (respectively), reducing the power gap with the Silverado’s 350kW/1322Nm 6.6L V8 turbo-diesel, while easily leap-frogging it for torque.

At 3710kg (kerb), the HD’s power-to-weight ratio improves significantly despite putting on about 100kg, from 76.5 kW/tonne to 84.4kW/tonne.

Meanwhile, a ZF-supplied eight-speed auto replaces the old six-speed unit. It’s now a second faster to 100 at under 7.3 seconds and the spread of extra gears should improve highway fuel consumption, albeit slightly.

Drive is sent to the rear wheels in two-wheel drive (2WD) mode in most cases. However, 4WD High (4H) is also available via a part-time dual-range transfer case and is selectable on-the-fly, though it is not recommended for operation above 80km/h, while 4WD Low (4L) is for rougher terrain at very low speeds.

Official fuel economy figures for the S7 Sportback are 8.5 litres per 100km, but in our brief time with the car we managed 13.6L/100km, mainly due to the inner-city and country B-road driving.

The 48-volt mild-hybrid system works to reduce fuel usage, by as much as 0.4L/100km according to Audi, and allows the car to coast with the engine off between speeds of 55km/h and 160km/h for up to 40 seconds.

The start/stop system also aids in reducing fuel usage.

Ram says the Australian Government doesn't mandate an official combined fuel consumption figure for full-sized utes like these, so there is no average economy number for us to share.

But the trip meter in two of our test vehicles said it consumed between 15 litres per 100km and 15.6L/100km of diesel fuel, and both had not been towing a trailer or load since being reset.

Despite the new ZF eight-speed auto’s revised final drive ratio (now 3.42:1 instead of 3.73:1) to help improve efficiency, clearly this is no Toyota Prius.

Based on those trip computer numbers, expect the 117-litre fuel tank to provide about 760km between refills. Handily, the 28.4L AdBlue reservoir comes with its own tank display on the dash.

Audi’s formula for a go-fast vehicle has always been simple – quattro all-wheel-drive for grip, potent engine for speed – and the new S7 Sportback remains true to that formula.

We are big fans of the 2.9-lite twin-turbo V6 engine, which is matched wonderfully with a smooth-shifting eight-speed automatic transmission.

The S7 Sportback always seems to have plenty to give no matter where you are in the rev range, and the transmission isn’t bogged down with slow gear changes up or down.

Though it’s hard to tell how much the EPC helps in getting the S7 up to speed, if you have you window down and accelerate hard from a standstill, you can hear the electronics whirring away.

The standard air suspension also does a wonderful job at absorbing road imperfections in comfort, while it can be switched over to dynamic for a more sporting characteristic.

Grip is plentiful thanks to 255/35 tyres and the quattro all-wheel-drive system but, as with other Audis, the S7 Sportback tends towards understeer when pushed hard around a corner.

Being such a long and wide model, you definitely feel the S7 Sportback’s size on the road, especially when navigating through quick direction changes, but this is where the $7700 Dynamic Package comes into play.

It adds a sports differential, variable ratio steering and all-wheel steering, all aimed at sharpening the S7 up in the bends.

Our test car was fitted with the option pack, but it left us a little cold.

The all-wheel steering especially, made the S7 Sportback’s handling feel too artificial for our tastes, and we were never able to gauge where the rear end wanted to go in a corner.

If we were buying one, we’d leave the Dynamic Package option box unticked.

Bringing the S7 Sportback to a stop are big 400/350mm brake rotors front/rear, with six-piston callipers in the front.

Ceramic brakes with grey-painted callipers can be optioned for $18,000, but the standard stoppers do a fine job scrubbing speed in the S7 Sportback.

The Ram HD’s column shifter and foot-operated park brake say it all. This is a big, floaty and, at times, old-fashioned American truck, and that is certainly how it feels from behind the wheel.

2500 HD first.

From the initial burble of the forced-induction in-line six diesel, you can feel the torque simmering restlessly within. Slot the awkward selector into Drive, and – depending on how much heft you’re hauling – the Ram will lurch off the line like a startled bull, and before you know it, you’re bounding along.

If lightly laden, you’ll even momentarily spin the rear wheels in the lower ratios – second (the start-off gear; first’s for lugging only), third and maybe even fourth if the surface is slippery enough, though the traction controls will quell anything more than a bit of a bum wiggle.

From there on in, on a straight piece of highway anyway, the 3.7-tonne ute just strides along effortlessly, picking up the pace with ridiculous ease as required. You’re soon aware that the cruise control is vital if you’re going to keep your licence.

If you’re wondering how different the HD feels compared to the related regular Ram 1500, the first corner will serve up some answers soon enough.

The steering is light and reassuringly measured in response, but also numb and less precise than expected, if not quite vague, meaning you need to feed in inputs carefully. Especially at speed. Rushing it in, or blundering through a tighter turn carelessly, will have the laws of physics reminding you of this truck’s length and girth, and not to mention maybe the long arm of the law on your tail as well before long. Anyway, other road users will soon let you know as well. Take it easy.

Over the varied and at-times tight rural roads of Victoria’s Gippsland region, the endless pitter-patter of the unladen suspension, combined with the constant pitching from the body and trigger-happy brakes, resulted in motion queasiness, if not sickness. We’ve been assured that with a load as intended, everything including our internal sense of balance should settle down. Which makes sense. A boat or caravan out back should provide the anchoring effect required.

Back on straighter and smoother ground, where the 2500 smothers and smooshes most things before it, you’ll be glad for the commanding vision aided by the massive mirrors and surround-view cameras, helping to boost driver confidence, particularly when weaving through traffic or in parking scenarios.

But the compromises demanded for the ability to haul up to eight tonnes means this is a very niche proposition.

Which is why Ram insisted on us testing the sole 3500 HD with a 3.5-tonne caravan hitched out back, on the ex-Holden speed loop at Lang Lang.

This was a test of acceleration and control, and – again – we managed to spin the rear wheels in the lower gears.

Likewise, all that torque was delivered without struggle or strain, and almost immediately the 3500 was sitting steadily at 110km/h. The planted chassis and various electronics seamlessly kept everything in line.

But the track surface was too calm to assess the ride comfort from the leaf-sprung suspension, and we weren’t allowed to venture on to public roads.

Returning back to base, we even forgot all about the caravan quietly shadowing our every move out back, which is a sign of the 3500’s towering towing confidence.

Which is exactly what it says on the tin.

Neither ANCAP nor Euro NCAP have tested any full-sized American utes at this stage.

However, the 2500 HD is alone in its class in having a National Highway Traffic Safety Administration rating for 2025, scoring four out of five stars.

For the Series II upgrade, the autonomous emergency braking system now includes cyclist and pedestrian detection and braking, the traffic-sign recognition tech is new, whilst rear-cross-traffic alert, blind-spot monitoring, a 360-degree view camera and tyre-pressure monitors continue. No operation parameter data for the AEB is provided.

Plus, dual front, front side and curtain airbags are fitted, along with three child-seat restraining top-tether points and a pair of ISOFIX latches in the rear outboard seats.

Like all new Audi models, the S7 Sportback comes with a three-year/unlimited kilometre warranty with three years roadside assist.

Audi’s warranty still lags behind Mercedes-Benz and Genesis, two premium marques that offer a five-year/unlimited kilometre warranty on their models.

Scheduled service intervals are every 15,000km/12 months, whichever comes first.

A three- or five-year service plan is available for the S7 Sportback, priced at $2350 and $4110 respectively.

So, here's where the news may not be so good for potential HD buyers, because the Ram’s warranty is well below its main competitor.

Now it is the sole US full-sized ute with a three-year, 100,000km warranty, instead of the five-year/unlimited-kilometre coverage offered by the others.

And don’t forget, this is the era where (albeit smaller) utes from Kia have seven years while Mitsubishi, Nissan and MG are up to 10 years (conditionally).

Service intervals are at just six months or 12,000km and there are no capped-price servicing options either.

As a result of trailing the competition so badly in these key areas, the Ram HD’s overall rating has been dragged down significantly.

Along with the 75 Ram dealers throughout every state and territory in Australia, there are an additional three garages that will service the vehicles.
