The Lexus RX, a staple in the luxury SUV segment, offers potential buyers a spectrum of powertrains, each tailored to a specific driving preference. One thing is certain however: Performance never comes at the expense of efficiency.

 

Let's delve into what each of these powertrain options brings to the table:

 

  1. RX 350 AWD's 2.4L Turbocharged Engine:

At the heart of the RX 350 AWD lies a 2.4L turbocharged inline 4-cylinder engine mated to an eight-speed automatic transmission. With this setup, drivers can expect an output of 275 horsepower coupled with a torque of up to 317 lb-ft. This pairing not only ensures a spirited driving performance but is also surprisingly fuel-efficient. It achieves a consumption rate of 11.2 L/100 km in the city, 8.4 L/100 km on the highway, and an average of 9.9 L/100 km.

 

  1. RX 350h AWD's Fourth-generation Hybrid System:

Stepping into the hybrid territory, the RX 350h AWD employs Lexus's esteemed Hybrid Drive technology. Central to this system is a 2.5L four-cylinder engine working in tandem with an electronically controlled continuously variable transmission. The outcome? A commendable net system output of 246 horsepower and a torque figure that stands at 233 lb-ft. Fuel efficiency is a standout feature here, recording ratings of 6.3, 6.8, and 6.5 L/100 km for city, highway, and combined driving respectively.

 

  1. The new RX 450h+ PHEV:

Under its hood, this model features a meticulously engineered 2.5L four-cylinder engine. This, in collaboration with an 18.1-kWh lithium-ion battery and a rear E-Four electric motor, culminates in a system output of 304 horsepower. The result? An exhilarating acceleration paired with the assurance of full-time all-wheel drive. This battery enables the RX to cover an estimated distance of 61 km purely on electric power. And while the powertrain goes about its business, passengers are treated to a serene ambiance, courtesy of an impressively quiet cabin. Fuel efficiency is exceptional at 6.5, 7.1, and 6.7 L/100 km for city, highway, and combined driving respectively.

 

  1. The New RX 500h AWD:

The RX 500h AWD showcases a cutting-edge hybrid electric system, boasting a net system horsepower of 366 and a torque that peaks at 406 lb-ft. It combines a high-torque 2.4-litre turbo engine with a six-speed automatic transmission. The rear, dubbed the eAxle, houses a potent electric motor, inverter, and a reduction gearbox. Such an arrangement benefits drivers by offering quick acceleration, courtesy of the electric motor's low-end torque, and sustained power even at elevated speeds from the turbocharged engine. With regard to fuel efficiency, it performs at 8.7, 8.4, and 8.6 L/100 km in city, highway, and combined conditions respectively.

 

The Lexus RX's powertrain options cater to a broad audience. Whether one seeks traditional turbocharged performance, the efficiency of a hybrid, or the best of both world, the new RX will deliver as it always has.
