Why switching to a Lexus RX450h hybrid is a smart decision

Not your average electrified vehicle
There is a lot demanded of the modern vehicle. More so with the takeover of electric vehicles just over the horizon. So why wait until more charging stations are set up when you can have an electrified vehicle now?
One of the greatest leaps in innovation is the evolution of the hybrid drivetrain. Who would have thought in such a short amount of time, we would see such massive improvements in fuel efficiency and lower emissions?
The drivetrain combines motive power from the gasoline engine and the electric motor, which are proportionally engaged depending on driving conditions. The engine automatically shuts off when the vehicle is at a standstill, and energy is regenerated by converting the vehicle's kinetic energy into electrical energy during deceleration and braking.
The very first luxury SUV hybrid, not just for Lexus, but the entire auto industry, was the Lexus RX 400h which went on sale in April 2005. Since then, Lexus has globally sold over two-million hybrid vehicles.
The RX badge continues to lead the charge among hybrid SUVs, and the current RX 450h is the result of years of development and improvement, not just in the efficiency of its hybrid drivetrain, but also in the driving experience. If you haven’t considered driving a hybrid, here are compelling reasons you should choose the Lexus RX 450h.
Engineered to perform
The RX 450h’s self-charging full hybrid system features a 3.5-liter direct-injection V6 petrol engine and front and rear motors. The total system output (engine and electric motors combined) amounts to 308-hp.
Chief Engineer Takeaki Kato said: “In developing the new model I was determined to keep and further refine the ‘one-of-a-kind’ value that only the RX could create, something which has been cultivated since the first generation.”
The key components and control systems in the Lexus Hybrid Drive System were improved and re-engineered to deliver class-leading fuel economy, minimal emissions, and excellent on-road performance.
The hybrid battery was repackaged, making it more compact and improving space efficiency. The RX450h’s E-Four all-wheel-drive system is a revolutionary new all-wheel drive that is compact, lightweight, and offers better performance and straight-line stability. Control functions were also improved to give a better response when accelerating through bends.
It’s paired with a Power Control Unit (PCU), and HV Engine Control Unit (ECU) that delivers better energy efficiency, more driver-friendly operation and more refined performance.
Unmatched luxury and convenience
Every RX 450h was crafted by Takumi master builders, and it shows in the stunning exterior and luxurious interior. The cabin design strikes a balance between functionality and luxury, finished with refined materials that exude quality construction and craftsmanship. The ambiance is spacious yet intimate, with high levels of comfort for driver and passengers.
Apple CarPlay and Android Auto come standard which allow you to use your smartphone via a 12.3in touchscreen display. Owners will also enjoy the hands-free power back door; clever cargo solutions with the fold-flat rear seats; LED headlights; illuminated exterior door handles; and the ornamented leather shift knob.
Other features showcased in the RX 450h are the Hybrid System Indicator that displays real-time information about the system’s output and regeneration; an EV Drive mode for silent and emission-free movement at low speeds; a drive-mode selector to match your driving style; a start-stop system that shuts off the engine when stationary; and Adaptive Variable Suspension for a smooth ride expected from a Lexus.
Advanced construction techniques
For added body rigidity that improves performance, handling and safety, Lexus engineers recommended additional spot welds and the use of structural adhesive to deliver a more rigid body. This increases the integrity of the panel joints, benefiting both stability and ride comfort.
The RX 450h is constructed using laser screw welding and high-tensile strength steel in key areas, as well as a ring-frame construction technique to add strength to specific frame sections. Areas around the rear body frame have numerous spot welds to give more strength and handling stability. These measures contribute to handling quality and cabin quietness, as well as the overall structural rigidity of the vehicle platform.
The RX 450h offers the latest in hybrid technology and production techniques. Priced at P5,238,000, it is an SUV that is luxurious, comfortable and easy to drive, particularly in urban environments where conventional 4x4s prove unwieldy.
