Toyota introduces new 2020 Highlander and hybrid at New York International Auto Show; TNGA-K platform

Toyota introduced the next-generation three-row 2020 Highlander SUV at the New York International Auto Show. Arriving in Toyota dealerships in winter, the Highlander gasoline model will arrive in December 2019 and the Highlander Hybrid will make its way to customers in February 2020.

Just as the first RAV4 launched the compact crossover SUV segment 22 years ago, the original Highlander redefined the midsize family SUV when it arrived in 2001. At a time when most midsize SUVs were truck-based, the Highlander’s unibody structure with four-wheel independent suspension became a template for a new segment of more comfortable and family-friendly SUVs. After adding a third row, the Highlander not only grew in size, but is also now the best-selling retail model in the segment since 2016.

The 2020 Highlander amplifies all qualities while taking on a new design direction that combines a powerful SUV presence with sophisticated detailing. The 2020 Highlander’s new look is based on a new vehicle platform called Toyota New Global Architecture (TNGA-K), shared with other Toyota models.

The fourth-generation Highlander offers the choice between a powerful V6 or new-generation hybrid powertrain, with the gas version offering a manufacturer-estimated 22 MPG combined fuel economy and the Hybrid offering an manufacturer-estimated 34 MPG combined fuel economy.

Hybrid. The new-generation Toyota Hybrid System in the 2020 Highlander Hybrid combines a high-efficiency 2.5-liter DOHC four-cylinder engine with two electric motors in a system that’s more compact, and more efficient than before. The gas engine employs Variable Valve Timing-intelligent system by Electric motor (VVT-iE) on the intake camshaft, and VVT-i on the exhaust camshaft. A variable cooling system (electric water pump, electric thermostat) and a fully variable oil pump further improve engine efficiency.

The system delivers a combined 240 horsepower and an EPA-estimated 34 combined MPG. The latter is a 17% improvement over the previous-generation Highlander Hybrid’s 28 combined MPG. Yet, Highlander Hybrid still delivers everyday acceleration, power and responsiveness. In another Highlander first, the hybrid is now available in either 2WD or AWD, further expanding hybrid technology to a new group of buyers.

The transaxle mounts the electric motors (MG1 and MG2) coaxially rather than in-line, and the resulting smaller and lighter package reduces frictional losses. The gas engine and MG2 work in concert to deliver dynamic performance, while both MG1 and MG2 charge the hybrid battery.

To reduce the transaxle’s size and weight, the reduction gear is now a parallel shaft gear, rather than a planetary, and a new multi-function gear integrates the power-split planetary ring gear, parking gear, and counter-drive gear. New computer integration and a smaller, lighter power stack installed directly above the transaxle reduce energy transmission losses.

The battery pack is small enough to be installed under the rear seats, so it does not take up any cargo or passenger space.

The new system optimizes the level of electric motor assistance and gas engine speed without the engine running at high revs. Engine speed is synchronized with vehicle speed, yielding effortless and quiet acceleration.

As on many modern vehicles, the Highlander Hybrid offers selectable NORMAL, ECO and SPORT driving modes that let the driver choose the vehicle’s performance personality. The bonus is the EV mode, which allows electric-only driving at low speeds for short distances.

SPORT mode unlocks boost from the hybrid system for improved acceleration response. ECO mode gets maximum efficiency from the fuel and battery, while NORMAL mode is ideal for everyday driving.

Special, easy-to-use hybrid tech adds an element of control and fun. Using a sequential shifting feature, the driver can “downshift” to increase the regenerative braking in steps, which fosters greater control when driving in hilly areas, for example.

The 2020 Highlander Hybrid can also coach the driver to drive as economically as possible. For example, an accelerator guide function suggests an acceleration level to the driver according to the driving conditions, and a scoring function adds a measure of fun to eco driving.

Highlander Hybrid’s Predictive Efficient Drive (PED) analyzes the driver’s daily driving habits and upcoming road and traffic conditions to more efficiently charge and discharge the hybrid battery accordingly alongside actual driving.

The more the vehicle is driven, the more data is accumulated, contributing to practical fuel efficiency. Many actual roads chosen to represent common usage scenarios, such as in urban congestion or on mountain roads, were driven on and analyzed to create control that feels natural to the driver when operating to enable more efficient driving.

Hybrid AWD. As with the AWD system in the previous Highlander Hybrid, the 2020 model’s AWD employs a separate rear-mounted electric motor to power the rear wheels when needed. Like the hybrid powertrain itself, the AWD works seamlessly and transparently.

The rear electric motor operates independently, with no mechanical connection between the transmission and the rear wheels. Preemptively distributing more driving force to the rear wheels, such as when accelerating, helps suppress front wheel slip during off-the-line starts. The system also enhances cornering agility by helping to reduce understeer. And, when venturing onto a trail, the increased rear-wheel torque helps move the Highlander Hybrid confidently over rough or slippery surfaces.

3.5L V6. The 295-horsepower 3.5-liter V6 features a Toyota-innovated D-4S Injection system that combines direct fuel injection with port fuel injectors to optimize efficiency, power and emissions in all conditions. Dual Variable Valve Timing with intelligence (Dual VVT-i) likewise ensures ideal response and efficiency at all engine speeds.

That translates into 295 horsepower and 263 lb-ft (358 N·m) of torque, which further translates into exemplary everyday performance and generous towing capability. The Direct Shift 8-speed automatic transmission maximizes Highlander’s acceleration and highway merging capability while operating seamlessly and transparently.

On V6 models, the available towing package enables a 5,000-pound towing capacity. The package includes a heavy-duty radiator with engine oil cooler and improved fan performance. Trailer Sway Control (TSC) uses the Vehicle Stability Control to help control unwanted trailer movement.

The Highlander’s standard Stop and Start Engine System allows the engine to shut off when the vehicle comes to a complete stop, and then instantly restarts when the driver’s foot lifts from the brake pedal. This technology reduces fuel consumption and cuts emissions.

Toyota Safety Sense 2.0 comes standard in all models in the 2020 Highlander. This comprehensive active safety system includes:

  • Pre-Collision System with Pedestrian Detection (PCS w/PD)

  • Full-Speed Range Dynamic Radar Cruise Control (DRCC)

  • Lane Departure Alert with Steering Assist (LDA w/SA)

  • Automatic High Beam (AHB)

  • (New) Lane Tracing Assist (LTA)

  • (New) Road Sign Assist (RSA)

Pre-Collision System with Pedestrian Detection offers automatic braking capability under certain circumstances should the driver not react in time in a system-detected emergency situation. Blind Spot Monitor (BSM) with Rear Cross Traffic Alert (RCTA), Parking Support Braking and Intelligent Clearance Sonar (ICS) are available depending on the model grade.

The 2020 Highlander delivers renowned Toyota value in a choice of five grades, starting with a new L grade, then layering amenities and technology in LE, XLE, Limited and the top-of line Platinum. (The Hybrid is offered on all but the L grade.)

The fourth-generation Highlander is 2.36 inches (60mm) longer than before, all in the cargo area to add even greater cargo volume than before. The second row can be slid an extra 1.2-in. further up to increase distance between the second and third rows.

The TNGA-K platform, which makes extensive use of high-strength steel, gives the Highlander a stiffer unibody structure than the previous model. Its inherent strength allows tuning for the front strut and rear multi-link suspension that enhances agility and a smaller turning circle while also providing a smoother and quieter ride than before.
