Motor Australia — January 2018

(Martin Jones) #1

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

The BMW is the lightest and most balanced of the trio.


It’s also the most supple and communicative
