Infiniti Q60

"Same taste, different bottle,” read the tomato sauce label. Have we reached peak tomato sauce, where the only improvements that can be made are to the bottle it comes in? Maybe.

Japanese upstarts Lexus and Infiniti reckon it’s the same when it comes to cars. Both think that a cheaper thing down the aisle can be just as good, if not better. With eyes now fixed on the six-cylinder luxury coupe, they’ve lopped two doors off their mid-size sedans and promised Tonkatsu tastes just as fine as Germany’s best pork schnitzel.

Going into bat for the status-quo is the BMW 440i. As our benchmark, it also needs to redeem a recent thumping the 340i took from its home continent rivals. Fresh from a mid-cycle update, retuned adaptive suspension in this car’s M Sport Pack teams with the brawny B58 inline-six, which upgrades the old N-series unit with more boost and a sturdier block.

But it seems beauty lies in the hands of the cheque holder. Even though the 440i seats fewer people, has fewer doors, and the same 240kW/450Nm as the 3 Series, it asks $10K more. Sure, $99,990 is line-ball with the Gran Coupe, but the regular 440i’s undisturbed lines and sleeker silhouette look sexier – especially in new Snapper Rocks Blue.

It’s the same at Infiniti, who gouge you $9K for the two-door equivalent of the Q50 Red Sport. The seductive coupe from Nissan’s Hong-Kong based luxury arm came wrapped in a fresh exterior last year, but don’t be fooled into thinking the Q60 is an ‘all-new’ car. It’s grown in length, width and the tracks are slightly wider. But that 2850mm-long wheelbase hints at Nissan’s FM platform which, after featuring in the 350Z, is due for a pension card.

At 1784kg the Red Sport’s steel-heavy structure and standard options list mean it’s 20kg heavier than a GT-R and the portliest here. Thankfully, this is countered by a plasma-sprayed, twin-turbocharged, direct injected 3.0-litre V6 seething with 298kW and 475Nm.

These sort of fangs make the Lexus RC350 whimper in its outlandish looking shell. Its dual-injected 3.5-litre atmo V6 boasts more displacement, but seems relatively grunt-less when 233kW and 378Nm lugs 1680 kilograms around. It’s also our cheapest. By shunning fancy Japanese wood trim, and active safety features, the RC can be had for $76,951 in F Sport trim. But a samurai sharp price isn’t the only reason we picked this F Sport. It scores exclusive ‘dynamic rear steering’, an LSD, and variable-gear electric steering.

The Lexus plays the outcast again at the drag strip. While the Infiniti and BMW pack V8-worthy twist, the F Sport’s torque-to-weight ratio of a regular hot hatch equals a 6.4-second sprint to 100km/h and the slowest quarter mile. It’ll break traction, but the 350 doesn’t get moving until 4000rpm. Besides this, what’s more frustrating is how little the RC revs for such an oversquare engine. Its 6600rpm redline is well short of its turbo competition, and the eight-speed auto won’t let you reach it, upshifting at 6200rpm – even in manual mode.

But its problems pale next to the Infiniti, which tries to squeeze all that firepower through relatively thin 245mm rears. Infiniti doesn’t make a 0-100km/h claim, maybe because the powertrain seems to have a mind of its own. With traction control on the seven-speed auto upshifts well before a 7000rpm redline to save the rear tyres from atomising, but with all systems off it can’t handle more than 50 per cent throttle. You have to baby it off the line, meaning the Infiniti’s grunt doesn’t count for much until Autobahn-worthy speeds.

Speaking of, the 440i is the only car to near its claimed time. Conjuring launch control requires sports mode and a 2500rpm two-step, good enough for a 5.1sec sprint to 100km/h. It’s grippy enough to do the times without traction control, but an LSD would help. The eight-speed also rushes its first few shifts to relish the engine’s low-down torque, but the six loves to spin past the indicated 7000rpm redline in higher ratios.

Things don’t improve on sodden, Victoria twisties for the Infiniti. Its suspension absorbs nothing and transmits everything. Potholes feel like they’re going to punch into the cabin and the chassis chatters over rough stuff like a pre-facelift Toyota 86, only with a longer wheelbase.

Infiniti says the steering’s been upgraded and while it’s more accurate, it’s frightening to drive fast in wet conditions on Dunlop run-flats. Rubbery steering weight and numbed feedback make it sometimes impossible to judge how much lock is needed.

Then there’s the rear axle, which has to deal with 475 newtons without any sort of torque vectoring technology. Even small throttle inputs make the stability light strobe like a disco. It has some grip, but a lack of composure. And after a crack, you bail out of the Infiniti exhausted, confused and disappointed.

While the Infiniti’s dynamics wash up terribly in wet conditions, the Lexus’s suspension isn’t so one-dimensional. The 350 F Sport is more comfortable at a brisker pace, as its chassis gizmos and stiff body give its Bridgestones a better side-step than its outright heft and nervous ride might suggest.

Variable-gear steering at both ends means it slices tighter corners with only a little lock. It doesn’t ride perfectly on its thinly padded 19s, even on adaptive suspension, and no matter what mode you pick (there are four to choose from) it struggles to settle after striking mid-corner bumps. But healthy damper travel and body roll are there to help extract more grip.

Switching to the BMW is like dropping a weight class. It’s not only the lightest and most balanced, it’s also the most supple and communicative. The updated suspension works better the faster you go, revealing feedback so you can barrel in with more confidence that the Pirellis will hang on.

The adaptive setup rides fine, and absorbs initial impacts well, even in Sport mode. However, it lets the car bob a little over bigger stuff. And with so much grunt so soon, the multi-link rear axle calls on the stability system often. But it’s at least worth trusting.

The variable steering rack isn’t the sharpest, and suffers from a typical lack of feedback under load, however, it’s geared well and feels more natural than the Lexus. This, combined with lush suspension compliance, make the 4 Series the easiest to snake through urban environments, too, with crisp throttle response and that silky ZF auto at the core of its driveability.

Without the bulging torque of the turbo cars, the Lexus feels a touch lethargic around town. You constantly dig deep into the throttle, even in Sport or Sport Plus modes, to wake a powertrain that prefers to zip through the eight-speed’s shortly stacked ratios as quickly as possible in search of a fuel-saving rpm.

The Infiniti’s the complete opposite, riding the V6’s tidal-like thrust the moment its turbos hit positive pressure. It’s laughable that the Q60 comes fitted with an ‘eco’ pedal, designed to push back against any throttle travel that might quench its thirst with more juice than needed. It would be like trying to cork the Snowy Hydro.

The upside to this is fearsome rolling performance, shooting the Infiniti from 80km/h to 120km/h in 2.8 seconds. You still nervously engage full power, even at speed, though. Max clog in the Lexus is a different event. Its relatively puny torque figure is delivered so high it never threatens the rear 265mm tyres once you’re moving, but adds 1.2 seconds to the same 80-120 sprint. Meanwhile, the BMW can’t use its healthy weight advantage to pip the more powerful Infiniti, its smaller twin-scroll turbine simply no match for the gut-turning acceleration offered by the Red Sport’s twin blowers.

On the opposite end of physics, and in complete contrast to the Red Sport’s steering, are its brakes, which are super strong and expose a lack of bite in the BMW’s non-M spec anchors. Meanwhile, braking distances show bigger front discs and higher friction pads in the Lexus are no match for its tubby kerb weight.

And on the inside? The Infiniti revels in glamour. Sparkling faux carbon-fibre runs down the centre stack arches, touchpoints feature traces of aluminium, and the seats are wrapped in semi-aniline leather. The thing’s nicely designed if you ignore the fact two digital screens are plonked on top of one another.

Scrounge around for pocket change and it’s not so pretty up close. The ‘optic-fibre’ inlays on the stack aren’t flush, and the floor-mat hooks are sharp enough for fish bait. Despite being the second most expensive car here, its dashboard is the only one daubed in plastic.

Slide into the BMW and it feels like you’ve sat down in an architect’s studio. It’s a bit bland at first; the pedals are rubber, and it’s covered in black and silver. However, its appeal grows with time. The important things – handbrake, seat switches, gear lever – are exactly where you want them. And the steering wheel is the best looking and the nicest to hold.

What’s surprising, too, is how much impact little changes to the interior have had. The iDrive button pad has sunk and is smoothed over, just like the indicator stalks, and the new digital dash is great. You can also see out of the thing better than the rest.

The Lexus, meanwhile, mimics a Ridley Scott film set. You stumble upon whorled stitching, falling buttresses, and a furled fascia. The carpet is thick, the pedals and paddles are metal, and everything turns or clicks with a solid, measured weight. The seats, which are heated, ventilated, and aggressively bolstered, would feel at home in something twice as expensive. Its refinement gives away nothing to BMW.

Functionality, however, is a different story. Buttons, knobs, pads, are everywhere. The dreaded track-pad remains frustrating, and linked to a dim-witted infotainment system. There’s a sneaking Toyota-ness about it, too, while fat body pillars eat into the glass house, making it more cab-forward than it should be.

Not one car makes a dud noise, though. The Infiniti wails like a muffled GT-R from the inside and out, while the BMW’s granular howl builds with timbre the more it revs. But it’s the Lexus which is most eventful. Its bellowing rumble coalesces with rich intake noise as soon as your foot kisses the firewall, helping it sound like you’re moving faster than in reality. An ‘ASC’ dial hidden by your right knee artificially enhances the soundtrack, but the engine sounds more convincing without it. Give it another 1000rpm instead, Lexus.

So have the Japanese proved differences between these three merely lie in a badge? Well, not in the Infiniti’s case. While it might seem like the real deal, with more features crammed in here than the latest iPhone X – seriously, the only options are paint colours – and an alluring look, the Q60 Red Sport proves to be all style, little substance.

Of course, that powertrain with endless grunt is an exception, but a wooden suspension setup, distant steering, and stiff ride make it hard to harness. The steering-by-wire answers an unasked question. It removes vibrations, yes, but with all the drive modes available, you should be able to lock up the ‘emergency’ clutch for a more direct feel when up it. You’d probably leave it on all the time, anyway.

You could swap the Lexus and Infiniti’s price tags and no-one would notice. That chassis might not sparkle with feel, but it has more dynamic talent than most 1700kg-odd rigs. There’s loads of grip at its limits, and you’d enjoy cutting track laps from morning ’til night. The interior feels lavish, and the noise from inside is enchanting. But the RC’s approach lacks clear thinking. We couldn’t master the throttle and steering’s ultra-lightness during commuting, no matter how much time we spent in it. And if only the F Sport’s engine could bite with the same anger as its bark.

The BMW’s challenge, however, is justifying the huge price difference between it and the Lexus. It starts well with more room in the back seats, a better ride, and a powertrain both blistering and civil. Its looks are less divisive, and you wouldn’t trade its iDrive system for a million Lexus track-pads. It feels the most natural to drive, and while you’d be looking around the Lexus cabin for the sound switch, selecting the right drive mode for decent throttle response, the BMW would have already pissed off like a Messerschmitt.

And so despite its price premium, BMW successfully fends off these Japanese upstarts to win our comparison. But while it’s a convincing victory against the Infiniti, you wouldn’t quite write off the Lexus. Three quarters the BMW’s price, it offers value for its plush interior, x-factor and dynamics. It’s not just a different bottle, if you like, but also a different and interesting flavour.
