Toyota Fortuner Hybrid: Technical Specifications & Advantages Explained In Detail
Toyota has introduced the Fortuner 48V hybrid in India, marking a new chapter in its hybridisation journey. This system is Toyota's initial step towards electrifying ladder frame vehicles, with the Innova Crysta and Hilux likely to follow suit. The 48V mild-hybrid system, first seen on the Hilux in South Africa last year, generates 11.5hp and 85Nm of torque.
Fortuner Hybrid System Details
The Fortuner's hybrid system shares many components with the Hilux. Both vehicles use a 2.8-litre common-rail diesel engine made in India, an e-motor/generator, a 48V lithium-ion battery, and a DC-DC converter. The electric motor-generator is a permanent magnet synchronous unit that produces 8.5kW or 11.5hp and 85Nm of torque.
This hybrid setup doesn't increase the maximum combined power of 204hp and 500Nm but enhances driving dynamics by providing an electric boost at low speeds. In comparison, the Hilux's e-motor delivers slightly more power at 12kW (16hp). The system promises to improve fuel efficiency by about five percent due to energy regeneration during deceleration.
Efficiency & Performance Enhancements
The Fortuner's fuel efficiency gains are attributed to energy regeneration and a reduction in engine idling speed from 720rpm to 600rpm. Drivers can choose between normal or long stop settings for the start-stop system, with enhanced air conditioning during longer stops. This flexibility contributes to overall efficiency improvements.
Toyota has ensured that the hybrid system is protected against water ingress. The battery consists of 13 cells, weighs 7kg, and is located under the rear seat alongside the DC-DC converter within the cabin. The motor/generator is positioned high up for protection.
Robust Design For Off-Road Use
The belt drive system has been reinforced for off-road durability with a two-arm tensioner designed for low noise and vibration. A high-strength cotton fabric layer on the ribbed side of the belt further reduces noise levels. Despite adding around 30kg to the vehicle's weight, this system significantly boosts efficiency.
Toyota has taken measures to ensure that this hybrid technology is suitable for off-road conditions by enhancing its robustness and reliability. The Fortuner's new hybrid system not only improves fuel economy but also offers better driving dynamics through its electric assistance at lower speeds.
