For those that want the ultimate luxury in Lexus, the all-new LS offers just that, along with a twin-turbo powertrain and loads of standard amenities. Now on its fifth-generation, the 2018 Lexus LS gets a more detailed exterior design and a longer body. Better Noise, Vibration and Harshness (NVH) deadening and new technologies such as 28-way power adjustable front seats come as standard. A 3.5-liter twin-turbo V6 lives under the hood and replaces the previous 4.7-liter V8. It is then mated to a ten-speed automatic transmission that drives the rear wheels.
