Interior design and technology – Toyota Corolla

Three Corolla body styles are offered: Hatchback, Touring Sports and Saloon. Toyota Manufacturing UK’s (TMUK) Burnaston plant in Derbyshire is Europe’s production center for hatchback and Touring Sports cars, with hybrid (1.8-litre) engines supplied by TMUK’s Deeside plant in north Wales. Sedan models are produced by Toyota Motor Manufacturing Turkey.

Inside story

Commenting on the major changes Toyota has made inside the latest incarnation, Rembert Serrus, Senior Director, Vehicle Performance, Toyota Motor Europe, said: “With the GA-C platform, the base of the windscreen has been lowered by 40mm and the overall height of the dashboard has been reduced to create a sleeker and lighter shape than before. As for materials and finishes, we have mapped the interior to ensure a consistent approach in all applications and, from the first 3D model, the shapes have been optimized in detail to give them an authentic appearance; for example, metal inserts have the look and feel of metal.

It is certainly true that the interior contact points are soft and plush. And regarding the measures taken to improve the car’s noise and vibration performance, Serrus added: “The overall cockpit sealing performance has been improved by using a much more efficient dashboard muffler with an exposed area. much smaller. There are also new door seals, rear wheelhouse silencers, front acoustic glass, etc.

Compared to its predecessor, the sculpted dashboard is slightly slimmer. Reducing the height of the overhead panel area reduces the perceived mass of the structure and improves the driver’s forward vision while allowing the front seat hip point to be lowered. The net result is a more engaging driving position.

The seven-inch instrument cluster includes the choice of a digital or analog speedometer. The steering wheel incorporates new heating and an optimized layout of the switches.

Toyota’s Touch 2 multimedia system sits in the center of the dash, an eight-inch touchscreen that controls various infotainment features, including a satellite navigation system.

All versions of Corolla are equipped with eCall, a system capable of automatically contacting emergency services in the event of an accident. Speaking of connectivity, several services are being rolled out after the launch of the car, including Last Mile Guidance, Send to Car Navigation, Driving Analytics and Maintenance Reminder.

As for the seats, the revised design of the front seats includes changes to the seatback and cushion springs and an optimization of the thickness of the urethane cushion.

New sports front seats in Hatchback and Touring Sports Excel models have thin, wide shoulder bolsters that overlap thick side bolsters. The Touring Sports and Saloon’s long wheelbase has increased front-to-rear torque distance by 48mm to 928mm, improving rear legroom.

Further back, the trunk offers 313 liters of storage capacity in the Hatchback version and 581 liters in the Touring Sports. Repositioning the rear shocks has simplified the structure of the sidewalls of the deck, maximizing the width of the cargo area, making loading easier and allowing storage pockets to be added to the sidewalls behind the rear wheel arches.

The cargo bed has a two-position tray (upper and lower). This opens and closes in the high position as if it were hinged on the backs of the rear seats. It is also reversible, with a carpet on one side and a resin finish on the other, suitable for carrying wet or dirty objects.

The space below deck has been enlarged, carpeted and fitted with removable side dividers. More comfort thanks to LED lighting in the load compartment, a claimed world first, on each side of the boot and a removable and retractable tonneau cover.

Other comfort and convenience features include a power tailgate with kick sensor (Touring Sports only) and an ever-useful head-up display (optional).

On the audio front, some versions of the Corolla can be equipped with an eight-speaker JBL Premium audio system. The loudspeakers have been specially adapted to the acoustics of the cabin. The system uses Clari-Fi technology, developed by Harman, which supplements real-time frequencies lost in compressed audio files, such as MP3s and streaming audio files. This restores the sound quality and stereo mix as close to the original recording as possible.

Active safety

All versions of the Corolla are equipped with Toyota Safety Sense, a suite of active safety technologies designed to help prevent or mitigate collisions. These include a pre-collision system, adaptive cruise control, lane departure warning, lane keeping assist, automatic high beams, traffic sign assist and start control. The latter helps prevent unintended or sudden starts of the vehicle when the driver operates the gear lever by suppressing power output from the transmission and issuing a warning to keep vehicle speed and acceleration below a level. predetermined. For example, if the driver presses the accelerator pedal when shifting from Park to Drive, the system will automatically limit power output to help prevent unintended acceleration.

The drudgery of parking is made easier with a park assist system that uses a rear camera and sensors on the sides and bumpers to identify viable reverse and parallel parking spots.

Passive safety

In terms of passive safety features, the Corolla’s body rigidity has been increased by around 60% through the increased use of adhesives and spot welds.

Hot-stamped, heavy-duty steel is used to reinforce the front and center pillars, front door beltline, roof rails, inner roof and front lintel extension, helping to suppress the deformation of the passenger compartment and to optimize occupant protection.

A new internal “floating island” hood structure helps reduce inertial G-forces at the onset of a crash and combines with a hood slat shock-absorbing structure to mitigate head injuries in the event of a crash. collision with a pedestrian.

All Corolla models are equipped with front and side airbags for the driver and front passenger, driver’s knee airbags and curtain airbags. The front seat belts have a newly shaped shoulder anchor that reduces the force needed to pull the belt. Belt lock sensitivity changed to make attaching smoother when the belt is pulled quickly. The adoption of a soft inner belt allows for easier fastening at any buckle angle.

Material issues

A reduction in the car’s body weight was achieved by using high-strength steel and hot-stamped materials, and by reducing the thickness of the door and roof panels. The automaker also added more spot welds throughout the body and used fully enclosed cross sections and structural rings. The net result offers an approximately 60% increase in body stiffness over previous Corolla/Auris models. Handling and agility are further enhanced by the low engine mounting height, a lower hip point for the seats and the location of the hybrid battery under the rear seats. Together, these measures lowered the center of gravity by 10mm.

Noise, vibration and harshness

To minimize noise and vibration entering the cabin, the engine installation has been designed to reduce vibration during start-up and idle. The increase in engine speed at the start of acceleration has been removed, to achieve both a more linear match between engine speed and vehicle speed and quieter operation under acceleration. The GA-C platform helps suppress drivetrain vibration, the steering wheel pad acts as a dynamic damper to suppress steering vibration, and even the toolbox design helps reduce vibration in the panel rear floor.

Additionally, a good portion of sound-deadening and insulating material in the engine bay combines with a three-layer interior dash muffler to minimize engine and transmission noise entering the cabin.

Particular attention has been paid to the floor. An integrated floor muffler, increased body sealant in the gaps between panels and injected foam material in various locations around the body to reduce wind and road noise levels in the cabin.

A question of specification

Six specification levels are offered, from the Icon, Icon Tech, Design, GR Sport, TREK to the Excel top drawer.

Overall, this renowned well-equipped model with a few neat touches felt lively, quiet and balanced through every turn. The clean cockpit with polished black panels and touches of metallic edging makes it a pleasant place to spend time behind the wheel. Satellite navigation and infotainment are easy to use without becoming too distracting.

It is also economical. Officially, the Excel Touring Sports 2.0-liter petrol hybrid will achieve 52 mpg. Our local run this week hit a perfectly enjoyable 49 mpg. Rival station wagon models include the VW Golf, Ford Focus and Skoda Octavia.
