There isn’t a lot purpose to take one other take a look at the 2021 Infiniti Q50 Pink Sport 400 on the floor. It’s largely the identical sedan because it was once we drove it in 2016: highly effective and trendy, however missing in tech and polish. Nevertheless, what’s beneath the hood is of much more curiosity to us immediately than it was only a 12 months in the past. That’s as a result of the three.0-liter twin-turbo V6 powering this Infiniti is migrating over to the subsequent Nissan Z automotive.
Nissan introduced that the manufacturing Z would get a 3.0-liter twin-turbo V6 not lengthy after it revealed the Z Proto. There aren’t any different twin-turbo V6s in Nissan’s arsenal however this one, which means that the VR30DDTT engine on this Infiniti is destined for the Z — plus, there’s photograph affirmation. The large query remaining is: How new or completely different will it’s?
Its most potent state of tune is rated at 400 horsepower and 350 pound-feet of torque. That’s a excessive quantity versus most different boosted six-cylinders, and maybe most significantly, it’s stronger than the 382-horsepower 2021 Toyota GR Supra 3.0. As we’ll quickly clarify, although, numbers solely inform a part of the story.
Transplanting the Infiniti’s V6 into the subsequent Z absolutely received’t be with out challenges, both. Nissan is promising a six-speed guide within the Z. In the meantime, this engine is solely paired with a conventional seven-speed computerized transmission within the Q50 and Q60. Nissan hitched this engine up with a guide in a 370Z SEMA present automotive years in the past, however now it should devise a manufacturing automotive answer. There’s additionally the query of whether or not Nissan will use the identical seven-speed as the automated choice within the Z, or give you one thing a bit extra aggressive. The price-efficient (and certain) answer could be reusing the seven-speed, not not like the Supra’s eight-speed conventional computerized.
Having all of this in thoughts, we got down to see how this engine sits immediately as a preview to the Z.
Going from the massive, naturally aspirated VQ sequence V6 to a smaller twin-turbo V6 will convey concerning the apparent adjustments. The rabid and uncouth character of the outgoing VQ is nowhere to be discovered within the candy and clean new engine. It’s not fairly the silky, easy BMW inline-six discovered within the Supra, but it surely brings an air of refinement and maturity that is merely not there within the present Z.
After which there’s the torque. All 350 kilos of twist can be found at 1,600 rpm within the Q50 Pink Sport 400, which suggests the shove within the again would theoretically begin simply off idle. In actuality, the Q50 feels as if it’s limiting torque output in low gears from a standstill, ensuing within the sensation of a slowed down begin in any takeoff that doesn’t contain brake torqueing it for a simulated launch. An amazing wall of torque arrives shortly as soon as the revs stand up, extending all the way in which to five,200 rpm. It has that easy and extreme feeling of energy for mundane driving {that a} luxurious sport sedan ought to have. There’s a slight disconnect at instances between throttle prodding and that shove within the again, but it surely’s anticipated while you resort to turbocharging for extra energy.
Fortunately, this engine is clearly tuned for driving pleasure while you do give it the boot. The mellow off-the-line begin in the end makes the Q50 really feel prefer it builds energy in a linear style as much as the 6,400-rpm horsepower peak. And also you received’t need to be quick shifting at 5,000 – this engine encourages the driving force to wind it out into the higher ranges and towards the 6,800 rpm redline. You may sense that it’s beginning to run out of breath proper on the high, however there’s no steep and unsavory drop off in energy. Simply shift, and maintain the occasion going. That’s precisely what we’ll need in a Z automotive that would discover itself on monitor utilizing up each out there rev.
Nissan will definitely tune the Z to sound completely different from the luxurious Infiniti, however this specific Q50 is an effective trace. Whereas the usual exhaust is unreasonably quiet, even for a sport sedan or the Q60 coupe, our take a look at automotive was fitted with the elective in-house axle-back efficiency exhaust that is exceptionally loud on the rear bumper. Begin-up is a imply, even growl. As soon as beneath approach, it is a distinctive and complicated tone of offended. As for the engine, you get subsequent to no turbo whooshes or associated turbocharger sounds. As an alternative, the dominating noise on the inside is consumption noise. You hear the V6 sucking in air all the way in which up the rev vary. This comes accompanied with a high-pitched yowl that begins low and will get extra frantic within the higher rpms. It’s a notice distinctive to this engine, giving it an intriguing character that units it aside from the various different boosted V6 engines of the world.
Is it as stunning and musical as a BMW I-6? Not within the least. However neither is it forgettable.
Forgetting concerning the transmission could be greatest, although. This seven-speed was merely workable as a efficiency slushbox 5 years in the past, and age has not helped it. Luxurious efficiency vehicles (and Supra) with the ZF eight-speed computerized outclass it in each approach — shift pace, response, smoothness, tuning in spirited driving. If something, the transmission dulls the drama and pleasure occurring beneath the hood. A quick dual-clutch gearbox, or higher but, a guide transmission might make this automotive come alive. The Z would profit vastly from a extra aggressive computerized, and if that isn’t within the playing cards, the guide will show essential to have essentially the most enjoyable. We simply hope the guide itself is an effective one – whereas the 370Z’s was serviceable and benefited from its pioneering auto rev-match perform, lots of Nissan and Infiniti’s most up-to-date efforts had been real stinkers.
The largest line-item Nissan might want to attend to with this powertrain, although, is in remodeling the engine right into a soulful and extra succesful powertrain within the Z. It’s no slouch within the Q50, however the acceleration figures reveal that its 400 horses don’t precisely translate to ahead momentum as you would possibly count on. Infiniti claims a 4.5-second dash to 60 mph. In the meantime in Germany, the BMW M340i and its 382 horsepower accomplishes the identical feat in 4.1 seconds. It’s additionally livelier on its approach there
In case you had been questioning if the Q50 Pink Sport 400 continues to be value your time in 2021 as a viable sport sedan, we now have some conflicting ideas on the automotive as an entire, too. The one replace for the Pink Sport mannequin is the provision of a brand new matte carbon fiber inside bundle and extra black exterior accents. It seems a contact extra menacing with these additions when mixed with the brand new Slate Grey paint. That mentioned, the Q50 is beginning to present its age, and the upcoming Acura TLX Sort S will simply outclass its design.
Dealing with is appropriate and competent for a sport-infused sedan, however the steering continues to be a sticking level. Infiniti’s elective steer-by-wire system has precipitated angst since its introduction, however even the conventional electrical steering present in our tester is devoid of most really feel and suggestions from the highway. It will get heavy in Sport and Sport+, however that’s all.
The automotive’s comparatively stiff journey with the dampers of their stiffest recommend higher dealing with functionality than what you get. The chassis holds its personal on a twisty highway when pushed; there’s noticeable physique lean, but it surely’s managed sufficient to retain cornering confidence. For its stiffer journey, we anticipated a bit of extra chew and sharpness in fast, successive actions. As is, it’s merely an average-handling sport sedan. Energy to the rear wheels on our all-wheel-drive automotive was acceptable for sheer grip, however the system is all about sustaining resolute traction. Different all-wheel-drive sport sedans on this class — BMW M340i, Mercedes-AMG C 43 — ease up on the rear-wheel reins to permit the rear finish to kick round and exhibit way more playful dynamics in consequence. Sure, they’re going to make it easier to keep out of that ditch in December, however they’re going to additionally let you could have some enjoyable in July. The stoic Infiniti system is not so involved along with your summer season plans. With 400 horsepower, it must be approach extra enjoyable to drive than it truly is.
Infiniti additionally lags behind others in its tech and inside high quality. The stacked dual-screen infotainment system provides you tons of display screen actual property, however this technique was dated the day it debuted. Years available on the market hasn’t improved issues. Moreover the performance of its twin display screen design being uncommon, it is not notably responsive nor trendy in look. Not less than it has Apple CarPlay and Android Auto, so you’ll be able to ignore most of what’s occurring elsewhere.
The cream-colored and diamond-stitched leather-based seats are an upscale contact, however the Nissan components bin controls and buttons feel and look low cost. And whereas it doesn’t want a digital instrument cluster, the design it’s at present sporting seems previous and is boring in look — it received’t even show a digital speedometer within the central display screen.
At our tester’s $61,890 asking worth, the Q50 Pink Sport 400 is a tough promote. The engine doesn’t current itself as an issue, although. As an alternative, it’s the substandard surrounding elements — transmission, inside and the fun-to-drive element — that make the automotive a secondary selection behind competitors just like the BMW M340i and Mercedes-AMG C 43. Nissan has the possibility to treatment these points with the Z and screw collectively a way more targeted sports activities automotive than the Q50 has ever been. With a bit of fiddling, some added drama and a great guide transmission, we’re hopeful that the Z can succeed with this twin-turbo V6.
