The American Toyota Corolla Hatchback Seems Really Impressive
Toyota in the United States has a new Corolla Hatchback for 2019 and it looks really great. It’s built on the Toyota New Global Architecture (TNGA) platform, and comes with loads of features to match its dynamic styling.
Toyota Corolla Hatchback has flair extraordinaire. With a theme of Shooting Robust, along with a design goal of Agile, influencing their every pen stroke, designers created a form that is simultaneously distinct, dynamic, muscular, and sophisticated. Shooting references the design’s sport coupe traits implemented in all facets.
With those concepts in mind, Toyota Corolla Hatchback is a meticulously mixed cocktail of emotive lines, creases, and surfaces. It’s lower (by 1.0 in.), wider (by 1.2 in.), and longer (by 1.5 in.) than its predecessor, Corolla iM. It also has wider front and rear tracks, and a longer wheelbase.
Its hood sits two inches lower than before, affording passengers excellent forward visibility. The new frontal styling with a rounded nose and trapezoidal-shaped under grille is a further evolution of Toyota’s Under Priority Catamaran and Keen Look design philosophies, both of which emphasize Corolla Hatchback’s increased width.
On the tech front, Apple Carplay and Amazon Alexa connectivity is present. The standard model includes an 8-inch. touchscreen; six speakers; Entune 3.0 App Suite Connect; Safety Connect; Wi-Fi Connect; Scout GPS Link Compatible; Siri Eyes Free; Auxiliary audio jack and USB 2.0 port with iPod connectivity and control; AM/FM; MP3/WMA playback capability; Voice Recognition training and tutorials; Hands-free phone capability; voice recognition and music streaming via Bluetooth; Customizable Home Screen; and Weather/Traffic info via Entune 3.0 App Suite.
The JBL audio experience with Clari-Fi – having such a complete orchestration of advanced power output, hardware, structure, and software – is engineered to impress even the most perceptive audiophile. Rounding off Toyota Corolla Hatchback’s connectivity are two USB terminals (located inside the center console and instrument panel) and one AUX port (located on the instrument panel).
TNGA isn’t just the genesis of Corolla Hatchback’s astute footwork and balance: An all-new TNGA-based powertrain is the heart of Toyota Corolla Hatchback’s Fun-To-Drive identity. Its 2.0-liter Dynamic-Force direct-injection inline four-cylinder engine (M20A-FKS) adopts the latest in Toyota technology and structural efficacies for gains in power, fuel efficiency, and cleaner emissions.
Physically, the engine is smaller and lighter than its 1.8-liter four-cylinder predecessor, which helps to lower Corolla Hatchback’s center of gravity and benefits its overall balance. The 2.0-liter is also quieter for improved Noise Vibration Harshness (NVH) with additions like a more rigid crank case with integrated stiffener; a lighter resin cylinder head; and a ribbed oil pan.
The M20A-FKS is equipped with Toyota’s latest D-4S fuel-injection that uses high-pressure direct-injection and low-pressure PFI (Port Fuel Injection). The setup adapts its injection method based on driving conditions so that ideal combustion is executed. The engine also features Dual VVT-i (Variable Valve Timing-intelligence), with VVT-iE (Variable Valve Timing-intelligence by Electric motor) on the intake side and VVT-i on the exhaust. VVT-iE uses one electric motor instead of oil pressure to control the variable valve timing. Together, the valve timing systems enhance power output and fuel mileage, and cut harmful emissions.
Other notable improvements to the Dynamic-Force engine include:
- Longer stroke
- Compression up to 13:1
- Enlarged valve nip angle
- Enhanced intake port efficiency with laser clad valve seat
- Higher rate of combustion, high tumble flow, and high intake air flow volume
- Pistons with round top surface and slanted side wall
- Consistent tumble flow and rapid combustion maintained
- Less knocking and higher compression ratio
- Friction reduction between piston skirt and cylinder
- Lubrication enhanced with three oil jets dedicated to each cylinder
- Better MPG, dynamic performance, less knocking, and less oil consumption
- Lighter weight timing chain
- Low cabin noise and reduced friction
- Drain path within crank case to return oil from cylinder head to oil pan
- Less oil agitation caused by the crankshaft, which means less rotation resistance
- Connecting Rod made of high strength steel with optimized shape
- Reduction in weight
- Camshaft with concave profile
- Increased valve lift amount
- Optimized water jacket in head and block
- Enhanced cooling and reliability
Be they a commuter or canyon cruiser, drivers will appreciate Corolla Hatchback’s available transmissions: an all-new Dynamic-Shift CVT (K120), or a six-speed iMT (Intelligent Manual Transmission) gearbox (EG60). The Dynamic-Shift CVT has simulated 10-speed Sequential Shiftmatic steps, Sport Mode, and paddle shifters. It features a number of innovative elements, including the world’s first launch gear in a passenger vehicle CVT.
Having a launch gear facilitates improved transmission efficiency in lower gear ratios where belt efficiency is typically poor. The transmission system utilizes gear drive when starting from a full stop, resulting in powerful acceleration, while at the same time, resolving the momentary sluggish feeling that was previously present during accelerator operation. Both smooth and comfortable launch performance are realized. When switching from gear drive to belt drive, the transmission system uses highly responsive gear change control technologies cultivated from automatic transmission technology.
With its launch gear in place, the belt has been tuned for higher gear ratios. This new setup not only improves the efficiency of belt operation, but it also enables the adoption of wider gear ranges, thereby realizing a class-leading gear ratio range of 7.5 for the 2.0-liter class.
Another benefit of the launch gear is a reduced input load. This enables the size of both belt and pulley components to be reduced. Furthermore, the belt angle has been narrowed and pulley diameters reduced, resulting in shifting speeds that are 20 percent faster. Powerful and predictable acceleration is realized, as is an endearing driving experience.
But the more involved driver will be engaged by the all-new six-speed iMT with downshift rev-matching control. Compared to the existing manual transmission, the new gearbox is lighter (by 15 pounds; total weight of 88 pounds) and shorter (by 0.94 inches), making it one of the world’s smallest transmissions. Its small size contributes to improved fuel efficiency.
