On December 16, Toyota released details about the 2022 Corolla Hybrid – the brand’s most fuel-efficient model ever to bear the Corolla name, an announcement said.

Achieving a combined fuel economy of at least 50 MPG, the 2022 Corolla Hybrid uses the latest Toyota Hybrid Hybrid Drivetrain and hybrid system that combines a 1.8-litre four-cylinder petrol engine with two engines. /generator and combined system power is 121 hp.

Standard equipment for each vehicle is the active safety system Toyota Safety Sense 2.0. Drivers can take command with a tilt/telescopic 3-spoke steering wheel, Dynamic Radar Cruise Control and Lane Departure Warning with Steering Assist. Onboard tech includes a standard 8-inch touchscreen with a six-speaker sound system. High-end instrumentation cluster with 7-inch color Multi-Information Display (MID) with customizable settings to keep the driver informed with hybrid system power meter, eco mode indicator, speedometer and tachometer, coolant temperature, one-touch 3-lane flashing turn signals, and warning messages.

Safety features include high-strength steel body panels to provide a strong shell for the single body structure, and energy-absorbing surrounds front and rear with active door beams. Side motion is standard on all models. On the inside, the Advanced Airbag System includes seat-mounted driver and front passenger side airbags, driver’s knee airbag, front passenger seat cushion airbag, rear seat side airbags, and front passenger side airbags. Air curtain front and rear. Toyota Safety Sense 2.0 comes standard with a Collision System with Pedestrian Detection, Lane Departure Warning with Steering Assist, Automatic High Beams, Road Registration Assist, Lane Keeping Assist and Cruise control with full-speed dynamic radar. Blind Spot Monitor with Rear Cross Traffic Alert is an available option.

Toyota says the hybrid and battery powertrain is a natural fit for the new Corolla because of the Toyota New Global Architecture (TNGA) platform. Nickel-metal hydride (Ni-MH) battery packs use a new technology called Hyper-Prime Nickel to increase battery performance. The battery’s smaller size and flatter shape allows it to be packed under the rear seats, rather than taking up trunk space, while also allowing the rear seats to split 60/40 to expand cargo capacity.

The motor works in conjunction with the electric motor (MG2) for responsive performance, while energy efficiency is achieved by using both the electric motor (MG1 and MG2) to charge the hybrid battery. When towed, the brand says, the battery provides a subtle power boost to put less strain on the engine and eliminate the “rubber band” effect experienced with some hybrids.

A preload differential adds to the sense of acceleration. During low loads and low differential revs, differential limited torque is distributed to the left and right wheels for stable handling. At medium and high engine loads, the preload differential acts as an open differential.

The Corolla Hybrid has an EV mode, which allows it to operate like a pure electric vehicle for short distances, subject to certain conditions, such as battery charge level. The Vehicle Distance Alert feature warns pedestrians of the presence of a vehicle when running in battery mode.

More effective is the Electronically Controlled Braking (ECB) system, which coordinates the action between the regenerative braking force of the electric motor and the force of the hydraulic brake system to provide stopping power. Toyota says if something goes wrong in the ECB system, the conventional hydraulic brake system can stop the vehicle.

The car’s petrol engine, the 2ZR-FXE 1.8L inline 4-cylinder, is designed for hybrid application. The long stroke configuration utilizes the Atkinson cycle, which utilizes a high compression ratio (13.0:1) along with a shorter intake stroke and longer expansion stroke than the Otto cycle. The Atkinson cycle extracts more power from the fuel, and the electric motors compensate for the low-end power loss (compared to the Otto cycle).

The exhaust heat recirculation system accelerates engine coolant heating, allowing the hybrid system to stop the gas engine earlier and more often in the driving cycle when it’s not needed. PTC (Positive Temperature Coefficient) heaters rapidly heat the cabin with electricity at cold temperatures.

The Corolla Hybrid rolls on 15-inch aluminum alloy wheels with low rolling resistance tyres. As on gas Corolla models, the new multi-link rear suspension improves agility and comfort compared to the previous-generation Corolla sedan.

Safety Features

The Corolla Hybrid comes standard with eight airbags and Toyota’s Star Safety System, which includes Advanced Stability Control, Traction Control, Electronic Brake-force Distribution, Brake Assist, and Anti-lock Braking System. and Smart Stop Technology. All Corolla models come with a backup camera as standard.

Notably, all 2022 Corolla models come standard with Toyota Safety Sense 2.0, an integrated suite of advanced active safety features, including:

  • PCS (Pre-Collision System) designed to automatically activate the brakes to avoid a collision or mitigate the impact. PCS can detect vehicles or pedestrians in daytime and low-light conditions, as well as bicycles during the day.
  • Full-speed DRCC (Dynamic Radar Cruise Control) designed for highway use, designed to maintain a set vehicle-to-vehicle distance and also capable at low speeds after reaching speeds of about 24 MPH. The Corolla can stop when the vehicle in front stops, maintaining an appropriate distance from it.
  • LDA (Lane Departure Warning) w / Steering Assist designed to provide the driver with audible and visual warnings and to provide steering assistance if it detects the possibility of leaving the driving lane. It also detects excess juxtaposition in the driving lane that may indicate a driver is distracted, inattentive or drowsy.
  • LTA (Lane Tracking Assist) enabled when LDA and DRCC are both on and active. LTAs that use lane centering generate continuous steering inputs to help drivers keep the vehicle in their lane. The LTA is designed for use on relatively straight highways to avoid unwanted lanes and reduce driver fatigue.
  • AHB (Auto High Beam), when enabled, detects the headlights of oncoming vehicles and the taillights of vehicles ahead and automatically switches between high and low beams as appropriate.
  • RSA (Road Sign Support) designed to recognize speed limit, Stop, yield and Do not enter signs and display them on the vehicle MID to help assist the driver.

The 2022-MY LE FWD vehicle starts at an MSRP of $23,750.
