Summary
Infiniti Q50
The Infiniti Q50 Red Sport sedan really wants you to love it, and this latest version is doing its best to impress the heck out of you with its looks and features.
So much so that you'll take it home... and live with it, forever. And then there's that engine – armed with a formidable twin-turbo petrol V6, the Q50 Red Sport's outpowers all its rivals.
But then there's the BMW 340i which is not that much more expensive... and it's a BMW. And what about the Lexus IS 350? That's more like the Infiniti, but also more popular.
Oh, and don't forget that we when first met the Q50 Red Sport last year we didn't exactly get off on the right foot. The engine's formidable grunt seemed too much for the car to handle. Then there was the jiggly ride, and the steering wasn't great either unless you were in Sport + mode. It's all coming back now...
Perhaps the Q50 Red Sport had changed. This is the new one, and Infiniti had assured us it's a different car now.
Do we give it another chance? Of course, and we do, in a quick 48-hour test. So, has it changed? Is it better? Would we live with it forever?

Mercedes-Benz C-Class
When it comes to choosing a family car, sedans are often overlooked for their long-legged wagon or beefy SUV cousins.
They're a bit of a forgotten hero but they'll always hold a piece of my heart for their practicality and (often) sexier kerb-side appeal.
If you can get used to your body cracking like a glow stick when you get in and out of them, the sedan may make a comeback!
The new Mercedes-Benz C-Class, in entry-level C200 form, has definitely tempted my family to consider a sedan in the future – it looks stately and refined but the driving experience also makes it fun.
Let's see what else it did right and if there was anything that could be improved.
Did I mention, I'm fond of sedans... ?

Verdict
Infiniti Q507.5/10
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.

Mercedes-Benz C-Class8/10
The Mercedes-Benz C-Class C200 is such a stylish sedan and I would totally have one. The driving performance, luxurious features and practical size made it a winning combo for my family. The price point is definitely up there but you do get a high-end build for the cash. I've seen bigger boots in other sedans and not being able to fit a third child seat will limit some families, but this still easily earns an 8.5/10 from me.
My son really loved this one. The ambient lighting was the highlight for him and he thought it looked like a "space car" inside. He gave it a 9/10.
Design
Infiniti Q507/10
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.
Mercedes-Benz C-Class
The C200 is a sleek and elegant steed.
Initially, you may think this is just a standard Merc showcase. There's the nice big badge on the pronounced nose. Beautiful sleek lines in the body... but it's the attention to detail that make this feel special.
There's a repeated badge motif in the grille and a cute cursive Mercedes logo tucked into the corner of the windscreen. The puddle lights on the doors project the badge at night time and you can often spot a badge etched into the LED lights.
However, it's the interior that's the highlight for me and I feel like it's a big step up from previous models I've been in.
Our model has the grey 'Artico' synthetic leather trim (says grey but it's really white) and a lovely mix of piano black and shiny chrome inserts that are set against soft touchpoints throughout.
The quality of the build oozes through every stitch and join. Don't even get me started on the cool customisable ambient lighting system inside, which makes this feel like you're on the set of Tron and really elevates the interior.
It's quite fun to build one of these in Mercedes' online configurator. You can customise your trims to make it feel like your own and their blue paintwork options are great (I do love a blue car).
Practicality
Infiniti Q508/10
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.
Mercedes-Benz C-Class
I'm not going to lie – there are sedans out there that have an almost limo-like space inside but the C200 isn't one of them.
It's not small by any means and all occupants enjoy the comforts of decent legroom and headroom but it's not cavernous considering the specs (1437mm high/1820mm wide/4751mm long).
The optional panoramic sunroof does cut into the headroom for back seat passengers, which is something to consider if your family is very tall.
The storage is maybe a tad leaner-than-average for a car of this size. The glove box and middle console aren't massive but will suffice.
The cupholders up front can be removed if you need extra storage space for larger items and back seat passengers enjoy retractable cupholders in the armrest.
The way the front doors curve out creates a larger than normal storage bin and drink bottle holder – which help make up the difference. There is a dedicated phone pocket, to tuck it out of the way.
The boot space is 455 litres (VDA), which isn't as large as some others on the market but it was plenty big enough for my family's needs.
There's a handy under-floor storage pocket for smaller items, like the puncture repair kit, because you don't get a spare tyre in this.
When it comes to ease of use, my six-year-old loved not needing my help to get into his seat and he still enjoyed a decent view out of the wide back window.
The amenities in each row are good but not class-defining. Still, creature comforts have be well-thought through.
Front occupants enjoy heated seats and fantastic lumbar and under thigh support. Dual-zone climate control sorts out the temp, and the cool circular air vents that make loud audible 'clicks' when manoeuvred give the interior a jet cockpit vibe.
While I've never had an issue opening or closing a sedan boot, the powered lid was a nice feature to have this week.
The tech throughout is great and intuitive to use. The massive 11.9-inch touchscreen multimedia system is cool and is easy to use once you become acclimatised to Mercedes system.
The customisable digital instrument panel makes the driving experiences feel individualised.
The interior is a chilled out space with gentle scrolling touchpads taking the place of most 'push' buttons and dials.
Think of each surface as being a bit like a touchscreen tablet in how you operate it. I was a little worried the touchpads would be laggy but they're very responsive.
There's only one USB port in the whole car, which limits charging for other passengers but I did enjoy the easy connectivity of the wireless Apple CarPlay.
The electric heated front seats are a nice touch but I was amused by the 'kinetic' function on both. It's what you might call a 'massage' function on another car but here they don't really work. It's best to think of them as a way to do some (very) gentle stretching on a long trip.
The 360-degree camera view is super clear and crisp but the dynamic guidelines (which tilt the camera angle) are a bit too dynamic for my liking and I relied mostly on the bird's eye view to park.
As I've mentioned, the ambient lighting system creates a stellar atmosphere inside. I've often wondered why other car manufacturers haven't jumped on that bandwagon because it's a relatively cheap way of creating wow factor. And it generates massive wow factor in here.
Price and features
Infiniti Q508/10
Maybe sit down for this next bit. The Q50 Red Sport lists for $79,900. Are you okay? Do you want a moment? Remember, though that only seems like a lot because it's not a Benz or a BMW. Truth is the value is pretty good – better than a German car of the equivalent size and grunt.
Look at the standard features list: 8.0-inch and 7.0-inch stacked touchscreens, the 16-speaker Bose 'Performance Series' stereo system, digital radio, road noise cancellation, sat nav, 360-degree camera, leather seats, power adjustable from sports seats, dual-zone climate control, proximity key, sunroof, auto wipers and adaptive LED headlights.
The 2017 update brought new standard features to the Red Sport including, red stitching on the seats and dash, quilted leather seats, new 19-inch alloy wheels and red brake calipers.
Don't forget that the bang-for-buck factor is strong with the Red Sport, too. In that nose is a twin-turbo V6 that makes almost as much grunt as the BMW M3 for about $100K less. Even the 340i, which Infiniti says is a Red Sport rival, is $10K more. Truth is though, the Lexus IS 350 is the real rival to the Q50 Red Sport.
Mercedes-Benz C-Class
Herein lies the rub. There are four models for the C-Class sedan and ours is at the bottom of the pack.
But don't let its position fool you in thinking it'll be cheap because this model starts at $78,900... and that's before you start adding the option packs.Â
Our model is fitted with the 'Vision Package' which adds a host of features – like a panoramic sunroof, head-up display and heated front seats, to name just a few. This adds about $3000 to the price tag.
This also has the optional 'Sport Package' which adds 19-inch AMG alloy wheels and rear privacy glass, among other things, for an extra $1300.
Unfortunately, even without all of those options, this is still one of the most expensive 'entry-level' sedans in the luxury class!
Under the bonnet
Infiniti Q508/10
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.
Mercedes-Benz C-Class
The C200 has a 1.5-litre, four-cylinder, turbo-petrol engine with an integrated starter-generator.Â
What's that, you ask? So, glad you did. It's basically an electric battery that also acts as your starter... or alternator.
It smooths out vibrations from the engine and generates some power from braking. Making this a very mild hybrid. Note the 'mild'.
Is it powerful? Surprisingly, yeah. It has a maximum output of 165kW and 300Nm of torque. Combine that with the starter-generator and we have a powerful little engine that can push the C200 from 0-100km in 7.3 seconds, while still feeling like there's power in reserve.
The nine-speed auto transmission is damn smooth and there's no clunky gear changing at any speed. It's got great pick-up, too, for when you need to overtake or zip across traffic.
Efficiency
Infiniti Q507/10
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.
Mercedes-Benz C-Class
The official combined cycle fuel figure is 6.9L/100km. Real world testing saw my figure at 7.2L, which was awesome for the heavy driving I did this week on a combo of urban and open-roads.
The light regen braking probably helps this coast comfortably into being a very efficient sedan for its size.
Minimum fuel requirement is 95 RON premium unleaded and you'll need 66 litres of it to fill the tank.
Driving range using the official consumption figure is around 950km, and 915km using our real-world number.
Driving
Infiniti Q507/10
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.
Mercedes-Benz C-Class
The steering feels solid and concise. The tyres seem like they're glued to the road, making winding roads downright fun to tackle. Oh, and the sharp 11 metre turning circle is wonderful.
The handling makes this your best friend in a car park. The lower ground clearance did elicit some unladylike grunts when I parked on a hill, but otherwise the wide door apertures makes it easy to get in and out of.
The only thing I would note is the low-profile ground clearance. Just be aware of your speed and angle when you handle car park ramps or road bumps in this. They are not your friends.
Safety
Infiniti Q508/10
The Q50 was given the maximum five-star ANCAP rating in 2014 and the amount of advanced safety equipment which comes standard on the Red Sport is impressive. There's AEB, that works forwards and when you're reversing, forward collision and blind spot warning, lane keeping assistance and moving object detection.
There are two ISOFIX points and two top tether anchor points in the back row, for child seats.
The Q60 Red Sport doesn't come with a spare tyre because the 245/40 R19 tyres are run flats, which means even after a puncture you should be able to keep driving for about 80km. Not ideal in Australia where distances are seriously vast.
Mercedes-Benz C-Class
The safety sheet is well-stocked and has the usual suspects you want in a family car, like: AEB with car, pedestrian, cyclist and junction turning assist (effective speed 7.0-90km/h); forward and back-over collision warning, lane keeping assist, lane departure warning and emergency lane keeping assist, as well as, blind-spot monitoring.
I quite like the 'Active Distance Assist' which helps to automatically slow your vehicle speed to keep a set distance to the car in front in stop-start traffic.
Perfect for those busy city commutes. And if you're not confident on parking, this also has a 'Park Assist' feature.
It's nice to see that this has nine airbags, which include a driver's knee airbag and the newer front centre airbag.
This has a maximum five-star ANCAP safety rating which is nice and new from testing done in 2022.
There are ISOFIX child seat mounts on the outboard rear seats and three top tether anchor points but because of the narrower rear seat, you'll only comfortably fit two side-by-side.
It was super easy to fit my seats and there's a good amount of room for front passengers when a 0-4 rearward facing child seat is installed.
Ownership
Infiniti Q507/10
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.
Mercedes-Benz C-Class
The C200 comes with a five-year/unlimited km warranty, which is standard for the market.
There are multiple servicing options and on the five-year plan, the services average $1090 annually, which is quite expensive.
Servicing intervals are pretty good at every 12 months or a longer than usual 25,000km, whichever comes first.
