Toyota C-HR on its way to Malaysia
Designed to stand out both within the Toyota line-up and in its segment, the all-new Toyota C-HR – or Coupe High-Rider – represents Akio Toyoda’s determination to allow greater stylistic freedom and promote engineering creativity in order to achieve eye-catching designs and enhanced driving pleasure.
The Toyota C-HR’s unique character demonstrates the flexibility that the TNGA (Toyota New Global Architecture) gives to vehicle developers in the three key areas of design, powertrain and dynamics, enabling them to deliver a new and fresh take on the increasingly commoditized crossover segment.
A NEW DESIGN DIRECTION FOR THE CROSSOVER SEGMENT
The all-new Toyota C-HR introduces a distinctive styling that brings newfound dynamism and sensuality to the crossover market, combining a coupe-like upper body with the powerful underpinnings of an SUV.
4,360 mm long, 1,795 mm wide, 1,555 mm high (Hybrid) and with a 2,640 mm wheelbase, the production vehicle remains remarkably true to the concept car’s exterior which was first shown at the Paris Motorshow in 2014, and which registered extremely well with target customers.
Under the concept of “Sensual Speed-Cross”, and featuring a diamond architectural theme with wheel arches projecting prominently at all four corners to emphasise the new crossover’s strength and rigidity, the C-HR modulated structure combines a powerful lower body and raised ground clearance with the slim and sleek cabin profile of a coupe.
Viewed from any angle, the C-HR’s combination of facetted gemstone-like shapes with fluid surfaces and elegantly integrated detailing create a delicate balance of precision and sensuality.
The front represents a further development of Toyota’s Under Priority and Keen Look design identity. The slender upper grille flows from the Toyota badge into the sleek, aggressive wing extremities of the headlamp clusters and wraps fully around the front corners of the vehicle.
The movement of the blacked out rocker panel towards the front and rear wheels, along with the shoulder axis that runs through to the front and rear, emphasise the fast-looking, ‘lift-up’ feel of the thin body.
The Toyota C-HR’s coupe-like styling is further enhanced by disguised rear door handles integrated within the C pillar and, essential to the representation of speed within the design, the powerful projection of the sweeping roofline into a large, highly aerodynamic, skeletal frame rear spoiler.
To the rear, the strongly tapered cabin integrates a top-hinged tailgate giving access to the loadspace that can accommodate luggage for 5 people. This contrasts with the pronounced flaring of the wheel arches, which give the new crossover a wide and extremely powerful stance.
Standing proud of the tapering body work, prominent rear light clusters may also be equipped with LED lamp technology to give the rear view of the C-HR an equally expressive visual signature.
SOPHISTICATED INTERIOR DESIGN WITH OUTSTANDING SENSORY QUALITY
A new departure for Toyota, the interior styling represents a new ‘Sensual Tech’ design concept combining high-tech functionality with a sensual and fashionable style. It embodies a driver focused area within an airy, expansive cabin space.
The warm, welcoming ambiance of an airy, expansive cabin space was created by the seamless layered architecture of the instrument panel that continues through to the door trim with a stylish ornamentation and a piano black panel. It offers a contrast between sensual surfacing and crisp lines to deliver a fresh, yet comfortable environment.
The driver oriented area incorporates innovative details and intuitive, approachable high technology. All operating switchgear, and an 8″ display audio touch-screen featuring a redesigned and improved HMI (Human Machine Interface) with Toyota’s Multimedia ’16 navigation platform and enhanced connected services are slightly oriented towards the driver.
In conjunction with the asymmetrical centre console design, this brings all controls within easy reach of the driver, whilst still allowing front passenger access to the relevant switchgear.
Because the touch-screen stands proud of the instrument panel rather than being enclosed by it, the upper dashboard is considerably lower in depth, further helping driver visibility.
A unique new two-tiered front seat design combines a slender, sporting upper section with a more strongly bolstered and supportive lower area, these differences emphasised through the use of differing tones, textures and patterns within the upholstery.
Targeting class-leading sensory quality (SQ), and knowing that C-HR customers will also have competitors from premium brands on their shopping list, the C-HR interior represents the earliest involvement yet of Toyota’s European SQ team in the design process.
Working closely with the headquarters design team to maintain the original interior styling concept, the SQ team have focused painstakingly on component quality, and the consistency of grain, texture, shape, colour and illumination in every element, even the stitch groove radii of the seats.
Reinforcing the link between interior and exterior design, many switches use a similar shape, reflecting the diamond motif of the exterior body shell. The same diamond theme is also visible in the door trim pattern, the headliner, the JBL speaker grilles and tweeter shape, and even the needles of the driver’s analogue instrument dials.
A carefully considered choice of finishes is essential to the harmonious, consistent, one-piece look of the new interior. There are three main surface finishes – leather-like for all background surfaces, a smooth Nappa grain for all touching surfaces and technical grain for all functional elements such as switchgear.
Decorative elements are finished in high quality piano black and satin silver trim, and the clear blue instrument and switchgear illumination has been carefully fine-tuned to ensure consistency of hue, even on adjacent reflective surfaces of differing colours.
This outstanding new interior design is available in a choice of three colour schemes: Dark Grey, Black/Blue and Black/Brown.
EQUIPMENT LEVELS TO SUIT THE MOST DEMANDING CUSTOMERS
Reflecting the demands of its target customer, the Toyota C-HR can be equipped with a wide variety of features. As part of Toyota’s commitment to democratise advanced safety equipment, Toyota Safety Sense is standard across the range. The system includes a Pre-Collision System (including Pedestrian Recognition), Adaptive Cruise Control, Lane Departure Alert with steering control, Automatic High Beam and Road Sign Assist.
Top-of-the-range customers will be able to specify heated seats, a smart entry system, privacy glass, bespoke upholstery including part-leather seats, Toyota’s revolutionary S-IPA system (Simple Intelligent Park Assist), 18″ alloy wheels and Bi-tone metallic paintwork.
TOYOTA SAFETY SENSE
Toyota Safety Sense helps to reduce the risk of a collision and delivers additional benefits by making life easier for the driver and reducing fatigue.
At speed ranges of between 10 km/h and the vehicle’s top speed this system uses a front-mounted monocular camera sensor and millimeter-wave radar sensor to detect vehicles and pedestrians on the road ahead. If it calculates a risk of a collision, it automatically warns the driver with a buzzer and alert in the multi-information display. At the same time the Pre-Collision Brake Assist engages to provide extra braking force the moment the brake pedal is pressed. If the system determines that the possibility of a frontal collision with a vehicle or pedestrian is extremely high, the brakes are automatically applied to help avoid the collision or help reduce the impact of the collision.
Toyota’s improvement of the technology has enabled it to recognize and react to the presence of pedestrians as well as vehicles and to function across a wider range of speeds.
Adaptive Cruise Control
The Toyota C-HR’s Adaptive Cruise Control with Full Speed Range Following Function makes use of the same millimeter-wave radar as the Pre-Collision system to maintain a safe distance from the vehicle ahead, slowing the car to a standstill if necessary and accelerating smoothly back to the pre-selected cruising speed once the way is clear.
Lane Departure Alert
Lane Departure Alert uses the camera on the windscreen to track the vehicle’s course between lane markings painted on the road surface. If it judges that the Toyota C-HR is about to move out of its lane without the turn indicator being used, the system sounds a buzzer and lights up a warning on the multi-information display. If the vehicle is still moving outside the lane, it will apply light steering force to assist the driver to bring the vehicle back on course.
Automatic High Beam
Automatic High Beam uses the same windscreen-mounted camera as the Lane Departure Alert. This recognizes the lights of oncoming vehicles or traffic ahead, automatically switching the headlights to low beam to avoid dazzling other road users and returning them to high beam as soon as the road is clear, maximizing night-time illumination and the driver’s field of vision.
Road Sign Assist
Road Sign Assist uses the front camera to recognize principal highway warning and command signs. These are then repeated on the multi-information display, reducing the risk of the driver not being aware of speed limits, lane closures and other important information.
Advanced safety and driver assistance systems
The Toyota C-HR is available with additional systems that support safer driving by giving the driver better real-time information about the area immediately around the car, including a Blind Spot Monitor and Rear Cross Traffic Alert.
The Blind Spot Monitor uses radar sensors mounted on the rear corners of the vehicle to detect nearby vehicles in adjacent lanes as they move into the driver’s blind spot. The driver is alerted to their presence by LED warning indicators in the door mirror on the appropriate side of the car. The LED indicators will remain illuminated as long as the vehicle remains in the blind spot. If the driver operates the turn indicators, intending to move into path of the vehicle, the LEDs will flash rapidly to draw further attention to the hazard.
The same radars are used to provide the Rear Cross Traffic Alert, monitoring approaching traffic from either side as the vehicle is reversed out of a parking space and warning the driver if any vehicles are detected.
Simple Intelligent Parking Assist system
The Toyota C-HR offers Toyota’s new Simple Intelligent Parking Assist (S-IPA) system, which uses an array of sensors to identify viable parking spaces and surrounding objects. Improvements to the technology allow it to work in parking spaces up to 22 per cent smaller than previously.
The driver stops the car next to the parking space and pushes a single button to engage S-IPA, which guides the car to the correct position for reverse maneuvering into the space. This system was developed to utilize the corner sensors for the parking assist.
CONCERT HALL SOUND
Recognizing the importance that the Toyota C-HR target customer attaches to the quality of the in-car entertainment system, the car can be equipped with a tailor-made JBL premium audio system comprising an 8-channel, 576 Watt stereo amplifier and 9-speakers, including two newly patented acoustic JBL wave guides, known as horn tweeters. It provides the ultimate sound reproduction in the C-crossover segment.
Because various elements of the interior such as the windows and upholstery, as well as the rigidity of the body structure surrounding each speaker, can have a significant impact on system sound quality, the system is the result of particularly close collaboration between JBL and Toyota’s engineers from early in the design process.
An in-depth customer analysis was taken into account for the system design and resulted in the orientation of the speaker layout and the use of a precisely integrated, A pillar-mounted horn tweeter -a JBL system signature- to deliver crisp, clear sound.
As well the two 25 mm horn tweeters and acoustic wave guides, the system further features two 80 mm wide-dispersion units and two 17 cm sub-woofers in the front of the Toyota C-HR, and, in the rear, two 15 cm full-range speakers and a 19 cm sub-woofer in a dedicated, 10-litre, ported enclosure in the boot.
Available in combination with the navigation option, the JBL premium audio system also incorporates lossless audio encoding.
The partnership between Toyota and JBL started in 1996 and has been successfully expanded since that time. Trusted by music professionals, JBL audio systems are used in major concert halls, venues and stadiums throughout the world (80% of live concerts, 70% of all recording studios and 90% of all THX-certified movie theatres).
Quality is the common focus of both companies, which has resulted in the all-new, uncompromised premium audio system specifically tailored for the C-HR.
STATE OF THE ART POWERTRAINS
The Toyota C-HR is equipped with an engine-range that is designed to deliver exactly the fluent, engaging driving behaviour that its customers are looking for. This is most powerfully expressed by the segment-unique, range-topping, full hybrid version, the intrinsic characteristics of which guarantee a smooth, jolt-free ride.
Fitted with the latest-generation hybrid power plant, the Toyota C-HR generates CO2 emissions as low as 82 g/km – a figure unrivalled within its segment – and returns combined fuel consumption of only 3.6 l/100 km. Delivering 90 kW/122 DIN hp, this new hybrid powertrain is not only more efficient and lighter than the previous system, but also offers sharper performance. Detailed design changes to the engine have resulted in a thermal efficiency of 40% – a world-beating performance for a petrol unit.
Other hybrid system components have been made lighter and smaller, and have been repositioned for optimum packaging, further contributing to the car’s low centre of gravity. This new hybrid powertrain offers the response and the fluidity of a dynamic driving style that particularly suits the Toyota C-HR’s dynamic design philosophy.
The Toyota C-HR is also available with a new 1.2 litre turbo engine, which debuted in the Auris. Delivering 85 kW/116 DIN hp and 185 Nm of torque, this unit generates CO2 emission from 125 g/km and returns combined fuel consumption from 5.5 l/100 km. It may be mated to either a 6-speed manual gearbox or a Continuously Variable Transmission. CVT equipped versions are available with either front- or all-wheel drive. And finally, a 2-litre 144 DIN hp/107 kW, 188 Nm CVT-only model will be available for certain markets.
NEW HYBRID SYSTEM
The Toyota C-HR is equipped with the new generation of Toyota’s signature hybrid powertrain. Toyota has focused its efforts on making this next generation of hybrids even easier and more intuitive to drive. The system has been set up so that it gives a natural, immediate, but smooth response to any accelerator pedal input. Refined and confident, it delivers the right level of performance.
But of course, fuel economy has been improved as well, as demonstrated in new Toyota C-HR’s combined cycle economy starting from just 3.6 l/100 km. The new hybrid system comes in a more compact package that is lighter in weight and lower in cost. It reflects significant advances in battery, electric motor and petrol engine technologies.
The new hybrid battery offers higher energy density. Whilst its total power was maintained, its size could be reduced by 10%. And what’s more, it can now absorb 28% more energy in the same amount of time, which means that it charges faster than before. The electric motors are smaller in size, yet also provide a better power-to-weight ratio. And the thermal efficiency of the petrol engine reaches more than 40 per cent, a world’s best for a petrol unit.
Improved petrol engine
The Toyota C-HR’s hybrid system features a 1.8-litre VVT-i Atkinson cycle petrol engine. Compared to the third generation Prius, the unit has been completely re-engineered to deliver significantly better fuel economy. The gas flow, combustion, cooling and knock control have all been improved and much more effective use is made of exhaust gas recirculation. Toyota has developed a heat recovery system that uses spent exhaust gas to speed the warming up of engine coolant. This means fuel can be saved because the hybrid system is able to stop the engine earlier and more often when it isn’t needed to power the vehicle. The engine is also helped to reach its optimum operating temperature more quickly thanks to a new dual-passage cooling system that can reduce the volume of coolant flowing into the engine, when required. This helps improving efficiency during cold weather.
Further work has been done to reduce energy losses, particularly through eliminating friction. Measures include the use of thin-section, resin-coated connecting rod bearings and a low-friction camshaft chain. Friction created by the piston skirts, rotating parts and oil pump has been reduced and a new electric water pump has helped cut the level of losses.
Conical “beehive”-type springs have been adopted to reduce the valvetrain load. And, to ensure comprehensive improvement, the entire engine underwent CAE analysis to achieve the best rigidity and to reduce noise and vibration. The intake and exhaust systems came under particular scrutiny, resulting in an engine that enjoys better breathing, air filtration, packaging efficiency, reliability and quietness. The air filter has been made smaller and reduced in height, which helped the designers bring down the line of the hood. The new intake system has a resonator that creates less noise at noticeable frequencies and the intake duct is made of a porous material that suppresses resonance.
A fresh air inlet duct has been added to make sure ample air volume is obtained at motorway speeds and a clever air/fluid separating structure has been added to keep water and snow from mixing with the intake air. Should the fresh air duct fill with water or snow, a secondary inlet serves as the air intake.
A thinner silencer secures optimum performance and noise reduction, while also improving the underbody aerodynamics and avoiding any intrusion on the space available in the trunk.
The engine block has V-shaped drilled paths that reduce losses in water jacket pressure. There is also a new water jacket spacer which helps control cylinder wall temperatures in the combustion chamber, reducing friction and preventing engine knock, which in turn supports optimum ignition timing.
Engine cooling has been improved with a new cooling module structure and attachment, and a redesign that accommodates a lower hood line and helps reduce the car’s centre of gravity. There is a new grille shutter behind the radiator which automatically closes when full airflow isn’t required, improving aerodynamic performance and saving fuel.
While engine cooling helps improve anti-knock performance, it can lead to an increase in cooling heat loss. To help counter this, Toyota engineers have developed a new water jacket spacer to control temperature on the surface of the cylinder. This keeps engine oil warmer with lower viscosity and reduces the temperature fluctuation. This helps reduce friction and allows more engine torque to be generated. At the top end of the temperature scale it reduces temperatures in the combustion chamber. The engine’s maximum output of 98 DIN hp/72 kW is delivered at 5,200 rpm, with peak torque of 142 Nm at 3,600 rpm.
