As a matter of fact, the key sub-100g/km CO2 figure is achieved by the IS 300h SE model, fitted with 16-inch wheels. IS 300h’s powertrain delivers a total output of 220 hp (164kW) and gives the new Lexus a dynamic drive with quick and smooth acceleration.
The hybrid system included in this Lexus model features a 141 hp (105kW) electric motor and a newly developed 2.5-litre four-cylinder Atkinson cycle petrol engine. The latter generates a maximum 178 hp (133kW) and in addition it benefits from a new D-4S fuel injection system, Dual VVT-i intelligent variable valve timing and a high-efficiency exhaust gas recirculation system.
In addition, rear wheels of the IS 300h are driven through the hybrid powertrain’s E-CVT transmission. The acceleration time from 0 to 100 km/h is measured at just 8.3 seconds on the way to a Vmax of 125 mph.
Furthermore, the driver can select the style of driving through different modes: EV all-electric running, with the petrol engine switched off; Eco, for optimum fuel efficiency; Normal, and Sport, for sharper throttle response and a sportier steering setting.
In the new IS range is included the F Sport model as well, which comes with sports-tuned suspension and electric power steering. It is also distinguished by a dedicated exterior and interior design features.
