Zoals eerder gemeld heeft ook Road & Track de 4e generatie Lexus GS gereviewt. De review van Road & Track is ook meer technisch dan de review van Inside Line. Road & Track gaat dieper op het onderstel en de verschillen tussen de normale GS 350 en het F-Sport variant hiervan. Hier is een stukje van de Road & Track review: (engels)

Fun-to-drive aspects of the GS prototype start with a refined platform that’s stiffer via added gauge and additional reinforcement here and there as well as an increase in spot and laser weld points. A newly designed unequal-length A-arm front suspension both widens the track by 1.6 in. and also sheds 4.4 lb., a significant portion of this being unsprung weight (the minimization of which aids road holding). At the rear, there are separate coil spring and shock mountings; this, to optimize their functions. There’s also a rear-placed toe control arm that plays more than a passive role when the car’s optional Dynamic Rear Steering is fitted.

The two prototypes differed in tire size, 235/45R18s on the lesser one, a front/rear split of 235/40R19s and hefty 265/35R19s respectively on the sportier one. The latter also had the full-house handling package with Lexus Dynamic Handling, Variable Gear Ratio Steering and the Dynamic Rear Steering already noted.

Verder is er ook een “Drive mode select” (zoals de Lexus CT deze ook heeft) met 4 standen, namelijk de Eco, Normal, Sport en de Sport S+:

 I also got to fool with Lexus’s latest Drive Model Select. A rotary knob on the center console gives options of Eco, Normal, Sport S and (if optionally fitted) Sport S+. The two Sport modes firm the suspension, modify steering feel, finesse the traction/stability control and affect shift schedules. If I had my dritters, I’d make S+ settings more aggressively recognizable. A center-mounted shifter has a left-gate slap-shift feature that’s also invoked (easier, I say) by steering-wheel paddles. Like the best of such systems, this one blips throttle artfully on manual-range downshifts.

Road & Track heeft ook een korte film van de Lexus GS in actie geplaatst:
