LOS ANGELES (November 28, 2018) – With the transformation of bumper-to-bumper, wheel-to-roof, 2020 the Toyota Corolla has become big news in the sedan for 2019. And now the most important, "But wait, there's more!" "Bonus: new hybrid models that achieve at least 50 mpg combined fuel economy (projected). That makes the Corolla Hybrid 2020 the most fuel efficient model that ever used the name of the model that debuted more than half a century ago.
The design is not the only thing that is thrilling about the Corolla Hybrid. This high-efficiency model adapts the latest Toyota Hybrid Synergy Drive from the new generation Prius, which has proven to be an MPG winner. Only Toyota offers a different choice of hybrids in this vehicle segment, thus serving customers who have different design tastes but the same desire for maximum fuel efficiency.
The 2020 Corolla Hybrid, like its gas-powered siblings, provides a very satisfying driving experience, along with the latest advancements in brand comfort and multimedia technology. As with the Corolla 2020 gas model, the Toyota Safety Sense 2.0 suite of active safety systems comes as standard.
The 2020 Corolla Hybrid is more evidence of Toyota's undeniable global hybrid leadership, which began more than 20 years ago.
Suitable for Hybrids
Powertrain and hybrid batteries fit naturally for the new Corolla because of the Toyota New Global Architecture (TNGA) platform. There is no compromise in the cabin room, for example, when choosing a Corolla Hybrid versus a gas model.
The new hybrid system combines a 1.8-liter four-cylinder gasoline engine with two motors / generators via an electronically controlled transaxle continuously variable transmission (CVT) type planet. The combined output of the 121 horsepower system produces clearly responsive performance.
The nickel-metal hydride (Ni-MH) battery package uses a new technology developed called Hyper-Prime NickelTM to improve battery performance in smaller and lighter packages. The smaller battery size and flatter shape allows it to be packed under the rear seat, rather than taking luggage space, and also allows 60/40 folding backrest to expand cargo capacity. The location of the battery also contributes to the vehicle's center of gravity, an advantage for agility.
The engine, working with an electric motor (MG2), ensures responsive performance, while exemplary energy efficiency is achieved by using both electric motors (MG1 and MG2) for hybrid battery charging.
Driving the Corolla Hybrid
The Corolla Hybrid linear acceleration response may be surprising. When withdrawing, the battery provides a smooth power boost to reduce the burden on the engine and eliminate the "rubber" effect experienced by some hybrids.
Preload differentials add to the feel of confidence acceleration. During low loads and low differential rotation, limited differential torque is distributed to the left and right wheels, resulting in excellent handling stability. At mid-range and high engine load, the preload differential function as an open differential.
The Corolla Hybrid has an EV mode, which allows the vehicle to be operated as a pure electric vehicle for short distances, depending on certain conditions, such as battery charge levels. This mode is useful for operating vehicles in parking lots or indoor parking garages, for example. The Proximity Notification Feature of the Vehicle warns pedestrians about the existence of the vehicle while running in battery mode.
Along with the expected NORMAL and ECO drive modes, setting the SPORT drive mode allows increased power for a stronger acceleration response when desired.
NORMAL Mode: Enables hybrid systems to achieve an ideal combination of fuel economy and vehicle acceleration. The accelerator opening number changes linearly in response to the accelerator operation.
ECO Mode: Increases the efficiency of a hybrid system by limiting power in response to light to moderate accelerator pedal input.
SPORT Mode: Available power increases, allowing an increased acceleration response.
Stop the Corolla Hybrid
Another push for efficiency comes from the Electronically Controlled Brake system (ECB), which coordinates the operation between regenerative braking forces of the electric motor and the style of the hydraulic braking system to provide optimum braking power. By proactively using an electric motor to recover as much electrical energy as possible from a regenerative braking system, this highly efficient cooperative control helps maximize fuel savings.
The active hydraulic booster in a conventional (non-regenerative) braking system increases the feeling of the pedal and feedback for the driver. Critically, if there is damage to the ECB system, a conventional hydraulic braking system can stop the vehicle.
Brake Hold, when involved, is an easy-to-use technology that reduces driver efforts while waiting at traffic lights or while driving in heavy traffic. When the driver presses on the gas pedal, Brake Hold will be released instantly.
How the other half works
The other half of the Hybrid Synergy Drive team, the gas engine, is no less impressive than the electricity side. The 1.8-liter inline 2ZR-FXE 4-cylinder engine is specifically designed for hybrid applications. The long-stroke configuration uses the Atkinson cycle, which uses a very high compression ratio (13.0: 1) along with shorter intake strokes and longer expansion strokes than the Otto cycle. The Atkinson cycle extracts more energy from fuel, and the electric motor compensates for the reduction in low-end power (versus the Otto cycle).
The friction created by the piston skirt, the rotating part and the oil pump is reduced, and the electric water pump eliminates the parasite loss with a conventional belt driven pump. Toyota seeks efficiency gains in each system. A highly efficient air conditioning system, for example, uses the S-FLOW control, which automatically optimizes air flow in the entire cabin according to temperature settings, the actual cabin and outside temperature, the intensity of sunlight, and seats occupied.
Getting the engine to operating temperatures quickly is very important to save fuel and reduce emissions at start-up. On the Corolla Hybrid, the exhaust heat recirculation system speeds up the cooling of the engine. Which in turn allows hybrid systems to stop gas engines earlier and more frequently in driving cycles when not needed, for example in conditions of low-power city driving.
PTC heaters (Positive Temperature Coefficient) quickly provide electric heat cabins in cold temperatures.
Corolla Hybrid rolls on 15-inch aluminum alloy wheels with low scroll resistance tires. As with the Corolla gas model, the new multi-link rear suspension improves both handling agility and driving comfort compared to previous generation Corolla Sedans.
The instrument panel uses high-quality gauges with 7-inch Multi-Information Display (MID). The MID shows the speedometer, as well as a hybrid system indicator / real-time battery charging status indicator. The ECO accelerator guide, also displayed in the MID, can provide guidance to maximize fuel efficiency by training the driver on the optimal gas pedal operation to suit driving conditions. Drivers who like visual appeal to see the engine rpm can choose to display the tachometer.
The multimedia offer for the 2020 Corolla Hybrid starts with the standard Audio EntuneTM 3.0 system which includes: 8-in. touchscreen display; six speakers; Apple CarPlay compatibility; Amazon Alexa; Entune 3.0 App Suite Connect; Security Connection; Wi-Fi connection; Compatible GPS Scout Link; Siri Eyes Free; additional audio plugs and USB 2.0 ports with iPod connectivity and control; AM / FM; MP3 / WMA playback capability; speech recognition training and tutorials; hands-free telephone capabilities; speech recognition; streaming music via Bluetooth; customizable home screen, and weather / traffic information through Entune 3.0 App Suite.
The Corolla Hybrid has eight standard airbags and the Toyota Star Safety System, which includes Enhanced Vehicle Stability Control, Pull Control, Electronic Brake Power Distribution, Brake Assistance, Anti-lock Braking System, and Smart Stop Technology. All Corolla models are equipped with a standard backup camera.
Toyota 2.0 Security Sense
Significantly, all Corolla 2020 models are equipped as standard with Toyota Safety SenseTM 2.0, a sophisticated range of integrated active safety features.
PCS (Pre-Collision System): Designed to automatically activate brakes to help avoid collisions or reduce impact forces. PCS is able to detect vehicles or pedestrians during the day and low-light conditions, as well as bicycles during the day.
Full-Speed DRCC (Dynamic Radar Cruise Control): Designed for highway use, which is designed to maintain a fixed vehicle-to-vehicle distance and is also capable of following low speeds up to around 24 mph. The Corolla can stop when the vehicle in front stops, maintaining the right distance for it.
LDA (Lane Departure Alert) with Steer Assist: Designed to provide audible and visual warnings to the driver and, if necessary, provide steering assistance if it detects the possibility of leaving the driving lane. It also detects excess weaving on the driving track which might indicate a driver's distraction, lack of attention or drowsiness.
LTA (Lane Tracing Assist): LTA is activated when LDA and DRCC are active and active. LTA uses a track centering function that will make a constant steering input to help the driver keep the vehicle on track. LTA is designed to be used on relatively straight highways to avoid unwanted pathways and reduce driver fatigue.
AHB (Automatic High Beam): When activated, it detects the front lights of the coming vehicle and the previous taillights of the vehicle and automatically switches between the appropriate high and low beams.
RSA (Road Sign Assist): Designed to recognize the speed limit, Stop, Yield, and Do Not Enter signs and display them on MID vehicles to help assist the driver.
