Paris Motor Show: Toyota unveils new Auris

  • Written by Aitor

The new Toyota Auris offers a bold and elegant design, higher quality interior and improved driving dynamics in its aerodynamics, in weight, in CO2 emissions and the combined hybrid system Full Hybrid.

Improved structure

The total length of the new Auris has increased 30 mm (maintaining a wheelbase 2.600mm.) And front and rear overhangs have increased 15 mm.

In contrast, the frontal area of ​​the Auris is down 4% compared to the current model and its height has been reduced by 55 mm, where the ranks 45mm the cockpit and ground level 10 mm. Combined, these changes offer considerable aerodynamic advantage, and contribute to better fuel economy and improved driving dynamics.

The widespread use of high strength steel in the body structure has helped to reduce the overall weight of the new Auris to 40 kg, while the total height reduction has also lowered the center of gravity. The height of the seats has been reduced 40 mm, and the angle of inclination of the steering wheel, 2 degrees, which creates a more engaging driving position with low waist.

The new design increases the front seat knee room in the back seat 20 mm, and the rear door opening has widened. The length of the boot has increased 50 mm, and the width of the tailgate, 90 mm. With the added flexibility of a rear shelf and a two-tier split folding seats with 60: 40, all versions, including the Hybrid, offer a greater luggage capacity of 360 liters.

More dynamic exterior design
Toyota's new look combines designer style lower grille Under Priority ("lower priority") with the Keen Look design concept ("sophisticated image") of headlamps and daytime running lights (DRL, Daytime Running Light ) LED, which give the Auris range a noticeably bold and powerful road presence.

Priority Under design incorporates a trapezoidal lower grille framed in the bumper, and a smaller upper grill
fills the space between the new headlights. Under the fluid low bonnet line, dominated by a new emblem
Toyota's largest and located lower than its predecessor, the upper grill incorporates a central bar chrome trim that extends visually to groups headlamps to accentuate the width of the vehicle.

In the front, narrower and with a sharper style headlamps, horizontal chrome bar flows to a form of "eyebrow" that accentuates the exceptionally meager distance between the hood and the Bi-HID (High Intensity Discharge) or halogen projectors. The innovative structure of the headlights also features daytime running lights (DRL, Daytime Running Lights) LED.

Flanked by integrated fog lights surrounded by chrome rings, the large lower grille combines a glossy black finish with chrome detail the lower edge of the wing, which also accentuates the width of the new Auris and emphasizes its presence.

In profile, under a sloping windshield that flows without jumps to a new and lower stepped roof line reduces drag a radical design change also involves lengthening the side windows on three panels above a waistline stronger upward.

The exterior mirrors have been repositioned in the window, hidden pillars are finished in glossy black and, in combination with the chrome trim waist line, more fluid and dynamic treatment of the rear pillars further accentuates the silhouette of the new Auris, lower, elegant and sporty.

The ground level of the new Toyota Auris has been lowered 10 mm, so that has narrowed the distance between the wheel arches and the tires and wheels are more aligned with the body, which further accentuates the slender look and perfected the new vehicle. For the wheels, you can choose between a new bezel design 15 "and 16" alloy wheels and 16 "and 17".

In the back, the wider opening of the tailgate has a concave and convex surfaces strongest. It is topped by a spoiler integrated ceiling and surround flanked by the new design of optical groups, which reinforces the shape of the tail fin and the moon, and the added strength of the fenders on the steps of the rear wheels. The new bumper with integrated reflectors at the ends reinforces the wide, stable and sporty rear image of the new Auris.

The new Auris will be available in a range ten exterior colors, four of which are new: Black, Bronze, Steel and Dark Blue. The Pearl White is unique to the combined hybrid models Full Hybrid.

Aerodynamics
The new exterior design makes the Auris has excellent aerodynamic performance, which helps to improve stability
operation and reduce fuel consumption.

In combination with decreased 55 mm total height, reducing 4% of projected frontal area significantly reduces wind resistance of the vehicle. Continuing downward, fluid bonnet line and steeply raked windshield, the stepped roofline reduces drag. Meanwhile, the rear spoiler is fully integrated into the rear roofline without jumps and connects with the rear pillar to minimize air turbulence flowing backward from the vehicle.

Besides reducing 10 mm above the ground, has been paid equal attention to ensure air flow most directly below the new Auris. The undercarriage includes a front spoiler, lower damping, lower engine cover, front spoilers, lower decks in the middle of the floor, on the sides of the tank and on the rear floor and rear baffles to maximize aerodynamic efficiency.

The aerodynamic performance of the lower power chassis thanks to the placement of vertical fins in the lower decks of the center and the rear of the soil, allowing the air to flow even better under the vehicle and results in a better handling and greater stability at high speed.

Following extensive aerodynamic measures, the drag coefficient of the new Auris has been reduced to just Cd Cd 0,292 0,28.

Interior design more uniform and higher quality
The new design, cleaner incorporates bolder shapes, excellent functionality and high quality materials.

The dashboard combines a marked sense to reinforce the horizontal width and breadth of the front of the cabin, with an arrangement of various instruments and more ergonomic buttons driver centered.

The new dashboard, simple and clear design two or three areas presents the needles and numbers on white. All buttons use the same font, and both the dashboard and center console are backlit in blue light to transmit a premium visual harmony and a full image.

To reinforce the sense of visual coordination in the new interior, the rings of the indicators, the core group, the transmission tunnel trim, climate controls and stereo and door handles have a satin metallic finish high quality game.

Vents, the stereo panel, the transmission tunnel, steering wheel and shift lever are finished with chrome paint. In later versions, the instrument panel also features a leather finish.

Sensory quality and visual harmony of the new interior is enhanced with the improved interior finishes, paying particular attention to the texture of all surfaces that come in contact with the occupants texture.

The upper surface of the dashboard and the door at the height of the shoulders are finished with soft-touch plastics, and pillars of the interior are covered with fabric. The knob of the gearshift has a new design, and the steering wheel is upholstered in Nappa leather, high-quality baseball style stitching. Both the upper gripper and the doors are finished in a smooth grainy texture, and the door armrests are padded.

With increased travel and height adjustment, the new seat design offers excellent comfort. Standard on the Style trim, the newly developed sport seat offers a high level of additional lateral support.

The seats of the Live finishes (basic) and Active (medium) are upholstered in cloth of high quality; Style trim seats (sports) incorporate panels in red. In terms of finishes Lounge (top), the seats are clad in black velvet with genuine leather reinforcements. Also available as an option in black leather finish Lounge models (top), while hybrid models can provide exclusive Ice Grey leather option.

The new Auris will be available with a new interior color combination of black matte textures. The grain matte leather with authentic look is created by combining a geometric dot pattern with a textured grained leather.

The practicality of the interior of the new Auris is evident in their functional characteristics and generous storage space.

So, have a glove a sunglass holder, hangers, purse, four drink holders and four bottle holders, a sliding armrest on the center console holders, space for small items on the dashboard and the back of the center console three 12 volt outlets and AUX external input, a removable tray packs, hooks in the trunk floor and rear shelf in two levels.

Improved Driving dynamics
The new Toyota Auris range incorporates improvements in body rigidity, suspension, steering, driving position and NVH characteristics, offering drivers a more comfortable and dynamic experience.

The widespread use of high strength steel in the body structure has helped to reduce the overall weight of the new Auris to 40 kg. Besides reducing the overall height of the vehicle has lowered the center of gravity, which improves vehicle stability at high speed and agility when cornering. This also allows a reduction of the levels of flexibility and the diameter of the stabilizer bar, which helps improve ride comfort, body control and steering response.

The MacPherson front suspension has been revised to combine comfort with stability and good steering response.
Models with petrol engine 1.33 1.4 liter liter diesel have rear suspension torsion bar, while models with petrol engine 1.6 liter liter diesel and hybrid powertrains 2.0 Full Hybrid mount double wishbone system behind.

The Electric power steering (EPS Electric Power Steering) also improved. The steering column is stiffer to ensure a linear steering feel, a new EPS control eliminates changes in steering force to improve linearity and high gear ratio enables a great steering response. In short, these reviews give the vehicle a more direct and faster turning response to increase agility.

The substantial improvement in NVH allows the new Toyota offers a quieter ride, supported by sound insulation of the engine compartment, the steps of the front wheel and dashboard.

Efficient petrol and diesel engines

The average emissions of the new Auris CO2 is 115 g / km, which represents a further reduction of 8% on average compared to the previous generation.

The key lies in the improvements made to the engine, which now lets you choose between a hybrid system combined Full Hybrid
improved and two petrol engines and two diesel.

1.33 dual VVT-i l
Equipped with the innovative "Start & Stop", the gasoline engine has double 1.33 liters Intelligent Variable Valve clearance (VVT-i Variable Valve Timing-intelligent) and a high compression ratio of 11,5: 1 that increases the thermal efficiency of the engine. Generates 73 kW / 99 DIN hp and maximum torque of Nm 128 3.800 rpm. It has a fuel consumption from 5,4 l / 100 km and emissions of CO2 from 127 g / km.

Motor gasoline Valvematic 1.6 l
Valvematic carries VVT-i technology a step further, adding an aperture control and variable valve duration to the intake valve. Thus better manages the volume and velocity of air inlet, and hence the combustion process, to deliver more power with less fuel consumption and reduce emissions CO2. The adoption of Valvematic system further reduces mechanical friction and pumping losses under light load for a consumer
even less fuel.

1.6 liter engine develops Valvematic 97 kW / 132 DIN hp and maximum torque of Nm 160 just 4.400 rpm. When equipped with manual transmission, the unit has a fuel consumption in combined cycle 5,9 l / 100 km, and generates emissions
of CO2 just 138 g / km, representing a reduction of 0,7 l / km and 100 12 g / km, respectively. Multidrive S transmission further reduces both fuel consumption and emissions, to 5,7 l / km and 100 134 g / km, respectively.

Diesel engine D-4D 1.4 l
Available with six-speed manual transmission or MultiMode transmission, engine D-liter develops 4D of 1,4 66 kW / 90 DIN hp and maximum torque of Nm 205 just 1.800 rpm.

A new hydraulic control valve in two steps cover the chain, which has the advantage of reducing friction when the hydraulic pressure is low, by opening and closing the pressure control valve according to the driving conditions is installed . The heating time of the motor is reduced to a minimum thanks to the installation of a new system coolant bypass helps reduce heat loss of coolant during startup.

The new generation of piezo injectors more precisely control the fuel volume and injection timing. The high speed response to the piezo injectors enable the multi injection at high speed. The result is that the degree of expansion of combustion, so it is more complete in the combustion chamber is reduced, thereby reducing emissions of particulates, NOx and CO2 further.

This, in combination with a pressure common-rail injection superiors, 160 MPa, resulting in a shorter injection, which provides faster engine response and lower levels of fuel consumption and emissions CO2. When equipped with manual transmission and technology "Stop & Start", the unit D-1.4D 4 90 has improved fuel consumption in combined cycle 3,8 l / 100 km, and generates emissions of just CO2 99 g / km, representing a reduction 0,4 l / km and 100 10 g / km, respectively.

Diesel engine D-4D 2,0l
The turbo diesel engine D-liter 4D of 2.0 126 CV DIN incorporates "Stop & Start" series, a new technology and turbocharger bearing system with reduced friction and an electric actuator. Improvements circuit
Lubrication and cooling are an oil pump pressure two stage process for enhanced oil injection, a water pump with a lower flow rate optimized water, and an oil pan dual chamber to enhance the rate of heating of the motor.

Exhaust emissions are reduced by controlling the spark plugs and improvements in the structure and the coating of the DPF.

The use of a resin cylinder head cover, radiator support oil and water pipe reduce engine weight in 3kg. The decreased friction, by adopting a vacuum pump with low friction, a distribution chain of low friction and low viscosity oil reduces fuel consumption. In addition, improved combustion, thanks to new concave shape of the piston and the new control strategy on, has substantially reduced the level of NVH engine.

As a result, the engine is quieter, the torque developed is superior and emissions have been reduced by CO2 19% of 138 to 112 g / km in the combined cycle. Fuel consumption has also fallen in 5,2 to 4,3 l / 100 km in the combined cycle.

MultiMode transmission
Available in diesel 1.4D 4 90 D-version of the new Auris, MultiMode is an automated manual transmission with a fully automatic shift mode and no clutch pedal. It allows the driver to choose between two modes: a fully automatic or a manual sequential shift paddles on the sides of the wheel.

Selecting E (Economy), M (Manual) or R (Reverse), the vehicle can move slowly as you would a conventional automatic. In the E mode, the vehicle automatically shifts gears to maximize fuel economy. If the ES (Sport) mode is selected, the shift to a higher gear will be delayed until a higher rate, to provide a more sporty driving style.

Multidrive S transmission
Available in the petrol version of the new Auris Valvematic 1.6, Multidrive S is a continuously variable transmission with a fully automatic mode or changing a sequential sports mode, speeds of 7.

In automatic mode, quiet operation and fuel system, accurately adapting the transmission to the engine at all times by controlling the angle of the accelerator pedal, the vehicle speed and the braking force is optimized.

In sport mode, the response of the system and the direct control of the engine is optimized. The stepped 7 speed CVT transmission has a short ratio gears to raise and direct sensitivity to downshift when braking and decelerating. Sport mode also has precise control in corners. By detecting deceleration, the system slows and applies engine braking to assist the braking force. A half turn, the system suspends the gear change if a lateral force due to acceleration is detected. Coming out of the curve, the predictive logic system downshift controls the system to ensure optimal gearing ratio to the required level of acceleration is selected.

Specific design of hybrid
The Auris hybrid shares the dynamic exterior styling changes and extensive interior improvements introduced in the new Auris, however both outside and inside incorporates exclusive details of the hybrid.
