Infiniti Q50 vs Renault Megane

What's the difference?

The Q50 Red Sport is a premium sedan that's great value, with a cracker of an engine. While Infiniti has improved the ride and steering, it still feels to me that the engine is too powerful for the wheels and chassis to handle. But if you're looking for something of an untamed beast, this car could be for you. Just don't say we didn't warn you.

If the Renault Megane RS Trophy is your dream car let me say this: there’s no overarching reason that I’d say you shouldn’t go ahead and buy it. 

But with so much amazing competition in this part of the market, it’s hard to put it ahead of its rivals. And it’s going to be even harder for it to stay high on the contenders list as more new metal arrives in the coming years.

The Q50 Red Sport looks cranky from front on, which I like in a car. Yes, the grille is simplistic and gaping, the nose is a bit bulbous, and sure, side on the car looks like a Lexus IS 350, but those rear haunches and the aggro body kit with its front splitter and boot lid spoiler make for an impressive looking four-door sedan.

The update brought restyled front and rear bumpers, those red brake calipers and the dark chrome 20-inch rims and new LED tail-lights.

Inside, the cabin is an asymmetrical paradise (or hell, if you're a bit OCD like me) full of sweeping lines, angles, as well as different textures and materials.

The red stitched quilted leather seats are an addition that came with the update, so is the new steering wheel and the ambient lighting.

The 'Sunstone Red' colour of our test car is also a new hue which looks a bit like Mazda's Soul Red. If red is not you, there are other colours – hope you like blue or white or black or grey because there's 'Iridium Blue', 'Midnight Black', 'Liquid Platinum', 'Graphite Shadow', 'Black Obsidian', 'Majestic White' and 'Pure White'.

The Q50 has similar dimensions to the IS 350: both are 1430mm tall, the Infiniti is 10mm wider at 1820mm,  120mm longer at 4800mm, and has a wheelbase that's 50mm longer at 2850mm.

The Megane RS Trophy’s dimensions don’t really communicate just how chunky it really is. At 4364mm long on a 2670mm wheelbase, 1875mm wide and 1435mm tall, it is pretty conventional in terms of size for the segment.

But it packs a lot of style into that size. I for one love those broad hipped wheel-arches, the signature LED headlights and chequered flag lighting signature at the bottom of the bumper, and the bright, eye-catching colours available really just ram the message home that this isn’t your average Megane.

I could happily leave behind the red flecks on the wheels, which look a bit too blingy and not quite ‘lightweight racing-spec’ to me. But they obviously appeal to a certain buyer - maybe someone who wants a bit more drive-by flair, as opposed to track-day talking points.

The Trophy model builds upon the Cup variant, using the same chassis and hardware under the skin, and therefore running the brand’s 4Control four-wheel steering and a mechanical Torsen limited slip diff. More on that in the driving section below.

Exterior design and styling are one thing - but you probably spend more time sitting inside your car than just admiring it from a distance. How does the interior of the RS Trophy stack up? Check out the interior images to make up your own mind.

The Q50 Red Sport is a five-seat four-door sedan and is vastly more practical than its two-door Q60 Red Sport sister, in that I can actually sit in the back seat. The Q60's coupe styling looks amazing, but the sloping roofline means headroom is so severely limited that it reduces the rear seats to a place to throw your jacket.

True, I'm tall at 191cm, but in the Q50 Red Sport I can sit behind my driving position with legroom to spare and more than enough headroom.

Boot space is good at 500 litres, which is 20 litres more than the luggage capacity of the IS 350.

Storage throughout the cabin is good with two cup holders in the rear centre fold-down armrest, two more up front and bottle holders in all doors. A large centre console storage bin and another big storage area in front of the shifter are great for keeping junk under control and your valuables covered.

The Megane RS Trophy’s cabin carries over some of the design cues from the exterior. It looks and feels like a hot hatch should.

There’s a lovely part-Nappa leather, part-Alcantara steering wheel with paddle shifters and a ‘centre line’ marker - but some may lament the lack of a flat-bottom to the wheel, which is a current trend in the “trust me I’m actually very sporty” breed of cars.

The manually adjustable seats are very supportive though they are a bit firm, so those wishing for ultimate comfort over long distance trips might be left wanting. But there is good adjustment to the seats, and they’re heated, too.

There are some nice elements to the cabin including soft plastics on the dashboard, but the lower plastics - below the eye-line - are quite hard and not very pleasant. However, the inclusion of ambient lighting does distract from that, and add a bit of flair to the cabin.

The portrait-style media screen is fine most of the time, though it does take some learning. The menus aren’t as intuitive as you might hope, with a mix of on-screen buttons and off-screen touchpad-style controls that can be difficult to hit when you’re driving. We also had a couple of instances of glitching while using Apple CarPlay and Android Auto smartphone mirroring.

Storage is okay. There are shallow cupholders between the seats, a covered centre console bin, as well as a storage section in front of the gear selector that’s big enough for a wallet and phone, and bottle holders in the doors. 

In the rear seat there’s enough space for someone my size (182cm) to sit behind their own driving position, albeit with limited knee room and toe room. Headroom is good, and there are dual ISOFIX child-seat anchor points and three top-tethers for baby seats.

You’ll find a pair of small door pockets, two map pockets, and rear-seat directional air vents, which is nice. There’s a flip-down arm-rest with cupholders, too, and unlike some other high-price hatches with ambient lighting up front, the Megane gets LED light strips on its rear doors, too. 

The boot space is good in the Megane RS Trophy, with luggage capacity claimed at a healthy 434 litres. On test, the car fit all three CarsGuide suitcases (124L, 95L and 36L) with room to spare. Speaking of spare (ahem), there isn’t one: it comes with a repair kit and tyre pressure monitoring, but no spare wheel of any kind. 

The Renault Megane RS Trophy has a list price of $52,990 for the six-speed manual, or $55,900 for the six-speed dual-clutch auto model, as tested here. Those costs are RRP/MSRP, and don't include on-roads. 

Standard equipment for this range-topping ‘regular’ RS model includes 19-inch ‘Jerez’ alloy wheels with Bridgestone Potenza S001 tyres, an active valve exhaust system, Brembo brakes, LED headlights with LED daytime running lights, rear fog lights, front/rear/side parking sensors, semi-autonomous parking system, reversing camera, auto locking, smart key card and push-button start, and steering column-mounted paddle shifters.

There’s also auto headlights, auto wipers, dual zone climate control, an auto dimming rearview mirror, heated front seats with manual adjustment, a nine-speaker Bose sound system with subwoofer and amplifier, an 8.7-inch touchscreen media system with aux port, 2x USB ports, Bluetooth phone and audio, Apple CarPlay and Android Auto, sat nav, the brand’s RS Monitor track timing software, and a 7.0-inch TFT colour screen for the driver with configurable modes and digital speedo.

You can find a run down of the safety tech and equipment fitted in the safety section below.

Options available include an electric sunroof ($1990), and there is also the choice of a few metallic paint colours: Diamond Black and Pearl White metallic are both $800, while the Signature Metallic Paint colours - Liquid Yellow and Orange Tonic as you see here - are $1000. Only Glacier White will cost you no extra. 

Wondering where it sits among its closest rivals? If you’re thinking about a Ford Focus ST (from $44,690 - manual or auto), Hyundai i30 N (from $41,400 - manual only), the outgoing VW Golf GTI (from $46,690 - auto only), or the mighty Honda Civic Type R (from $51,990 - manual only) the Megane RS Trophy is expensive. Only the VW Golf R Final Edition ($57,990 - auto only) is dearer… unless you’re thinking of comparing to the likes of a Mercedes-AMG A35 ($69,300).

Inside the Q50 Red Sport's nose is a 3.0-litre twin-turbo V6 petrol engine and it is a beautiful thing. To me this car is piece of technologically sophisticated jewellery that cradles a precious gem that pumps out 298kW/475Nm.

But I have my concerns... you can read about those in the driving section.

Shifting gears is a seven-speed automatic which delivers drive to the rear wheels.

Engine specs matter if you’re talking about performance hatchbacks, and the Megane RS Trophy is no exception.

It has a 1.8-litre four-cylinder turbo-petrol engine that punches hard for its size, with 221kW of power (at 6000rpm) and 420Nm of torque (at 3200rpm). That’s for the six-speed dual-clutch automatic transmission, as was fitted to our test car. If you buy the six-speed manual, you miss out on a bit of grunt - it has 400Nm (at 3200rpm) and the same peak power.

In auto spec the RS Trophy “300” offers higher figure vs the Sport and Cup “280” models (205kW/390Nm), and more engine performance per litre of capacity than the Focus ST (2.3-litre: 206kW/420Nm), Golf GTI (2.0-litre: 180kW/370Nm; TCR 2.0-litre: 213kW/400Nm), and even the Golf R (2.0-litre: 213kW/380Nm). 

All Megane RS models are front-wheel drive (FWD/2WD) and no Megane RS is all-wheel drive (AWD). The Trophy and Cup models both get 4Control four-wheel steering, which is an interesting aspect of the drive experience. More on that below. 

There are multiple drive modes to choose from, including Comfort, Neutral, Sport, Race and the configurable Perso mode. These can alter engine, transmission, throttle, traction control, exhaust noise, fake engine sound and steering sharpness - but not suspension, because the dampers aren’t adaptive units. 

Infiniti says the V6 petrol engine in the Q50 Red Sport should use 9.3L/100km if you're using it on a mix of highways, urban streets and country roads. We only had the Q60 Red Sport for 48 hours and after a couple of days of Sydney city commutes and a trip to the Royal National Park our trip computer was reporting 11.1L/100km.

The claimed official combined fuel consumption for the Megane RS Trophy is 8.0 litres per 100 kilometres. That’s for the EDC auto model as tested. The manual is said to use 8.3L/100km.

You might achieve that if you drive gently, though over my testing - which incorporated hundreds of kilometres of highway and country road driving, as well as a few spirited stints and some urban snarls - I saw a return of 10.8L/100km at the pump.

The Megane RS requires 98RON premium unleaded, and the fuel tank capacity is 50 litres. 

Perhaps the biggest complaint we had about the previous Q50 Red Sport, which launched in 2016, was that it felt as though the chassis wasn't up to the amount of grunt running through it, and those rear wheels struggled to transfer the oomph to the road without losing traction.

We experienced the same issue again in this new car. I was breaking traction, not just in 'Sport+' and 'Sport' modes, but in 'Standard' and 'Eco', too. That was happening without pushing it hard and with all electronic traction and stability aids on.

If I was 18 I'd declare to the world I'd found my dream car - something that always wants to 'light 'em up' given half a chance. But like that one mate who always gets into trouble on a night out it's only funny when you're young.

A truly great performance car is planted, balanced and able to deliver the grunt to the road effectively. The Nissan R35 GT-R is the perfect example – a brilliant piece of machinery, a weapon of a performance car and with a chassis matched perfectly to its engine.

And that could be the issue with Q50 Red Sport - that engine feels overpowered for the chassis, and wheel and tyre package.

We also felt the previous Q50 Red Sport's ride, with its constantly adapting 'Dynamic Digital Suspension', was overly busy. Infiniti says it has developed the suspension system further and it does feel as though the ride is more comfortable and composed.

Steering was another area that we weren't overly impressed with when we drove the previous car. Infiniti's 'Direct Adaptive Steering' (DAS) system is super sophisticated and was the first in the world not to have any mechanical connection between the steering wheel and the wheels – it's all electronic.

The new Q50 Red Sport uses the upgraded 'DAS 2' and while it feels better than before, it's only in Sport+ mode that it seems most natural and accurate.

The Megane RS Trophy has the ingredients to be an all-time legendary hot hatch, but they don’t work together well enough for it to be a truly great car to drive.

That is, they don’t work together on public roads. I didn’t get a chance to sample the RS Trophy at the track, and I’m sure that may well alter some of my opinions. But this was a review focused around everyday driving first and foremost, because - unless you’ve got quite a fleet of cars - you’ll be spending a lot of time in mundane motoring in your Megane RS, too.

Other hot hatches in the segment manage to combine big power and torque with immense traction and steering prowess. The Megane RS used to, as well.

But this new version seemingly has some issues harnessing the grunt, and the 4Control four-wheel steering system simply isn’t as rewarding as it should be.

I had several instances where the traction on slippery surfaces was lacking, while even in the dry I noticed distinct torque steer and the Bridgestone tyres struggled to cope under hard acceleration. That’s despite the fact the Trophy gets a mechanical LSD.  

Further, that four-wheel steering actually makes it pretty hard to judge the behaviour of the car at times, with an artificial feel to it that just doesn’t do it justice. There will be some who say that the four-wheel steering - which can angle in the rear tyres to help you pivot in corners more adeptly - is excellent. But I’m not one of them. I really found it hard to predict this car’s behaviour. I never really gelled with it.

At the very least there’s a non-interventional lane keeping assist system, which emits a pulsing sound through the speakers rather than actively vibrating or adjusting the steering. 

The ride is unapologetic in its firmness – although, if you’re across the history of RS Megane models, that is to be expected for a Trophy chassis. It can be tiring on longer road trips especially if the surface isn’t great.

While it is extremely fast in a straight line - 0-100km/h is claimed at just 5.7 seconds - it wasn’t as quick through corners as I was expecting it might be, and that comes down to its four-wheel steering mostly, along with a lack of usable traction at times. It simply isn’t as connected to the road as the previous RSs have been. 

It was also a bit laggy then lurchy at lower speeds when taking off from a standstill, such is the nature of the dual-clutch in stop-start situations. 

To put it bluntly, I didn’t enjoy this car anywhere near as much as I thought I might. It just isn’t as pure a driving machine as I’ve come to expect from the RS brand. Perhaps I should aim to try it on a track!

The Renault Megane has not been awarded an ANCAP crash test rating, but the regular (non-RS) model scored five stars against EuroNCAP criteria back in 2015.

The RS Trophy (manual or automatic) comes fitted with adaptive cruise control with speed limiter, auto emergency braking (AEB) at speeds between 30km/h and 140km/h, blind spot monitoring, lane departure warning with audio alert, reversing camera, surround parking sensors and semi-autonomous parking.

Missing is rear cross-traffic alert, front cross-traffic alert, rear AEB, pedestrian detection and cyclist detection. 

The Q50 Red Sport is covered by Infiniti's four year/unlimited kilometre warranty with servicing recommended every 12 months or 15,000km.

Infiniti has a scheduled servicing program which will cost $1283 (in total) for three years.

The Renault Megane RS range is covered by a five-year/unlimited kilometre warranty, which adds some peace of mind for owners.

Further, the service intervals are generous, at 12 months/20,000km - though the brand states the Megane RS is actually “subject to adaptive servicing requirements” as the oil condition sensor may trigger a service check requirement prior to the standard intervals.

Unlike other Renault models with a five-year capped price servicing plan, the Megane RS is only covered for three years/60,000km. The service costs for the EDC dual-clutch auto models are higher than the manual versions, due to replacement transmission oil being needed (adding $400 to the first service). 

The costs for the first three services are: $799 (12 months/20,000km); $299 (24 months/40,000km); $399 (36 months/60,000km). Consumables beyond those service intervals include: every 24 months or 20,000km - air filter replacement ($49) and pollen filter replacement ($63); every 48 months or 60,000km - accessory belt replacement ($306). Spark plugs are included at no cost, due every 36 months/60,000km.

The car is backed for up to four years of roadside assistance when serviced within the Renault dealership/service network.
