2016 Lexus GS facelift arrives at Pebble Beach with new 200t rear-wheel drive version
Lexus has introduced the GS facelift at Pebble Beach where it shares the spotlight with the 2016 LX 570.
The biggest news is the addition of a 200t rear-wheel drive version with a 2.0-liter, four-cylinder gasoline engine also seen in the RC 200t and NX 200t. It pumps out 241 bhp (180 kW) and 258 lb-ft (349 Nm) of torque and works exclusively with an eight-speed automatic transmission granting the vehicle with an estimated fuel efficiency of 33 mpg US (39.6 mpg UK or 7.1 liters / 100 km) on the highway.
This new member joins the existing GS 350 which soldiers on with a V6 3.5-liter which for the 2016 model year has gained an extra 5 bhp (4 kW) and 3 lb-ft (4 Nm) for a grand total of 311 bhp (232 kW) and 280 lb-ft (379 Nm) channeled to the same eight-speed auto.
The GS 450h continues to use the same hybridized V6 3.5-liter with 338 bhp (252 kW) transferred to the road via a CVT. This hardware setup enables the model to perform the 0-60 mph (0-96 km/h) run in 5.6 seconds and return an EPA-estimated 29 mpg city / 34 mpg highway / 31 mpg combined cycle.
In terms of styling changes, the 2016 Lexus GS facelift has a modified front end with a more aggressive spindle grille and bi-LED headlights along with updated taillights and some rear bumper tweaks. Other novelties include standard navigation for GS 350 and GS 450 h models, a bigger 4.2-inch instrument cluster display and a 12.3-inch screen for the infotainment system.
Also new for the 2016MY are several exterior and interior colors, wheel designs, wood and aluminum cabin trims and a Lexus Safety System + that packs Pre-Collision System (PCS) with Pedestrian Detection, Lane Departure Alert (LDA) with Steering Assist, Intelligent High Beam (IHB) and All-Speed Dynamic Radar Cruise Control.
