Body and Chassis
The body shell of the Lexus IS manages to be both lighter and more rigid than that of its predecessor. They've also worked on the packaging, with the IS 300h being the first Lexus full hybrid to have its battery beneath its luggage compartment, not in front of it - the move means that the boot capacity is unchanged from the non-hybrid models.
The Lexus IS300h is motivated by a duet between a 181 HP, 2,494 cc four-cylinder petrol engine and a 105 kW (143 hp) electric motor. The four-pot is a new engine and it runs according to Lexus' favorite Atkinson cycle, also featuring D-4S direct injection, as well as Dual VVT-i variable valve timing.
In between the two units and the driven rear wheels sits an Electric Continuously Variable Transmission (E-CVT), which channels the 223 HP overall output of the system.
At the rear of the 2014 Lexus IS, we find a new multilink suspension, including a subframe and cowl lateral braces designed to make the car sharper. The front suspension has been reworked, with one of the most important changes being the adoption of thicker anti-roll bars.
The F Sport package brings a bespoke implementation for the suspension, as well as for the Electric Power Steering. Choosing this also brings 18-inch wheels, as well as an optional Adaptive Variable Suspension (AVS). This allows the driver to choose between normal and sport damping modes.
Since the F Sport pack doesn't bring extra power, the standard brakes of the car were kept. This means that the front axle features vented discs in a size of 296x28 mm, while at the back we have 290x10 mm non-ventilated rotors.
Before we end, we have to explain that the limitations of the powertrain, as well as the built-in understeer given by the suspension setup have determined us to withdraw a point for this chapter.Continue reading
