Powertrain and Performance
Sold exclusively with the Luxury trim level, the debuting RX 450h+ receives a 304-hp gas-electric plug-in hybrid powertrain incorporating a 2.5-liter four-cylinder gasoline engine, an electric motor, a high-capacity lithium-ion battery, and a continuously variable transmission (CVT) with paddle shifters. All-wheel drive is standard. According to the manufacturer’s estimations, this efficient midsized crossover achieves a combined 83 MPGe and can travel up to 37 miles on exclusively electric power. When it’s plugged into the standard 6.6kW onboard charger, it takes approximately 2.5 hours to reach a full charge.
