Volkswagen Jetta 2011 Design

DESIGN

The new Jetta is a completely redesigned vehicle – and never before has a Jetta been this large, this sporty or this independent.  Just how independent is evident from the fact that the Jetta no longer shares any body components with the Golf.

Measuring 4,644 mm in length, the Jetta is 90 mm longer than the model it replaces, with a wheelbase increase of 73 mm to 2,651 mm.  This allows the rear legroom to increase by 67 mm.

Exterior
Through the interplay of its new exterior dimensions, the Jetta’s design generates a powerful ratio of proportions.  In parallel, the addition of Volkswagen’s latest ‘design DNA’ sharpens the car’s styling.  As a result, clear, precise lines and muscular surfaces impart a timeless elegance and dynamic styling to the saloon and give the impression that it is a car from a higher class.

At the front the coupé-like incline of the windscreen and the consistent use of horizontal lines define the Jetta’s design, emphasised by the high gloss black radiator grille and trapezoidal headlights.  The dual round headlights are subdivided by so-called masking blades to form a large upper area with dipped and main beam lights and a narrow lower area with daytime running lights and indicators.  The chrome masking blades continue the horizontal emphasis of the front end lines right into the headlights making the Jetta appear wider and more dynamic.  Under the grille and headlights is the cleanly sculpted surface of the fully painted bumpers, and below this, an air intake and tray-shaped front spoiler give the front end a sporty finish.  Also designed to be aerodynamic, the Jetta has a Cd value of 0.302.

The transition from the V-shaped bonnet into the side wings produces a powerful effect.  The shoulder section implemented here contributes to the car’s dynamic and muscular styling.  In the Jetta’s side profile, design characteristics that have defined all new Volkswagens of the past year meld to create another interpretation of the ‘design DNA’ conceptualised by the Italian Head of Design of the Volkswagen Group (Walter de Silva) and the German Head of Design of the Volkswagen Brand (Klaus Bischoff).

The best example of this is the so-called character or ‘tornado’ line which cuts through the large side surfaces and gives a strong, dynamic appearance.  The door mirrors are designed with integrated turn indicators in the form of narrow stripes, as on the new Passat.

The wheelarches are striking.  Thanks to the wide track (front 1,535 mm, rear 1,532 mm) they form a precise transition.  Another typical design characteristic is the line work in the area of the C-pillars.  Here, the trailing edge of the door follows a straight line from the side sill diagonally back into the triangle window; stylistically, this lengthens the door and gives the overall vehicle an even larger and more elegant appearance.

Harmonised surfaces and sporty shoulders also dominate the look at the rear of the Jetta.  The very wide rear window with its coupé-like angle offers excellent rear visibility and at the same time it emphasises the car’s dynamic lines.  Its interplay with the C-pillars, as striking as they are elegant, and the clearly sculpted shoulder section, produces a design that is extremely dominant with a strong presence.

Equally prominent are the rear lights.  They are split into two sections, extending from the wing into the bootlid and displaying an unmistakable look both day and night.  The bootlid itself has an aerodynamically optimised trailing edge that minimises air turbulence and increases the car’s downforce to the road.  The vertical surface of the bootlid with its integrated ‘VW’ logo and segmented rear lights shows a slight flare – a styling tool that further emphasises the new Jetta’s sportiness.  To access the 510-litre boot, the bootlid can be opened by remote control.  A special, patented reflector illuminates the entire lower registration plate and boot area together with a uniform light.

Volkswagen Jetta 2011 Interior

Interior
The Jetta’s interior is designed to be of the highest quality.  It’s also created to be comfortable and ergonomic, with all controls within easy reach and intuitive to use.

The silver framed round instruments are designed in the style of the new Passat and are positioned for optimum viewing; the multifunction display (trip computer) is located between them.  The new three-spoke steering wheel design impresses both visually and to the touch.

Further up the centre console are the redesigned and intuitive controls for the climate control and the radio.  This console section is slightly inclined towards the driver to make it easier to see and access.

The handbrake lever has been repositioned, freeing up more space that is now used for larger cup holders.  Numerous storage options all perfect the car’s everyday practicality.

Despite the flatter roofline, the effective headroom for both driver and front passenger has been increased to 1,014 mm.  Both occupants take their places on completely redesigned and ergonomically optimised seats that offer a high level of long-distance travel comfort and ample adjustments.  The extended wheelbase, now 2,651 mm, enables a significantly more comfortable layout of the rear space.  Consider knee room: it is now an impressive 1,046 mm, while headroom in the rear, at 943 mm, is still as good as on the previous model.

The folding rear seat has a split 60:40 and combined with a load-through provision enhance practicality.  The 510-litre boot can be opened from inside the car by a remote switch (or by unlocking from the exterior or via the standard remote locking key).

Volkswagen Jetta 2011 Interior Climate Control

Climate control
The Jetta comes as standard with a semi-automatic climate control system known as Climatic.  To keep the cabin fresh and well ventilated there is a good flow of air to front and rear passengers, as well as a pollen filter which operates in both fresh-air and recirculating-air modes.  Using a simple dial control, the Climatic system maintains the desired cabin temperature automatically whatever the temperature outside.

A 2-zone Climatronic climate control system is available as an option in the Comfortline and Highline trims.  This two-zone device allows driver and front-seat passenger to adjust theirown climates individually and independently.  Temperatures within the two zones are maintained to an accuracy of a degree, with no readjustment necessary whatever the outside conditions.  The Climatronic’s intelligent control system even takes into account the amount of sunlight penetration into the cabin, and makes separate calculations to compensate for it on both the driver and passenger sides.

As an example of further attention to detail, the system switches automatically to recirculating-air mode when reversing and when the windscreen washer sprays are used; the fresh air supply is momentarily cut to prevent smells – of exhaust and windscreen wash – from entering.

ENGINES

The Jetta is available with a choice of five engines: three petrol units – a 1.2 TSI 77kW, 1.4 TSI 90kWand 1.4 TSI 118kW plus two diesel units: a 1.6 TDI77kW and a 2.0 TDI 103kW.

Petrol engines

1.2 TSI with 77kW
The 1.2 TSI four cylinder engine is new in the Jetta model line-up. Like all TSI engines, it too follows the TSI downsizing philosophy with its 1,197 cc displacement. This means maximum power with minimal fuel consumption.

From standstill, the 77kW Jetta 1.2TSI accelerates to 100 km/h in 10.9 seconds and its top speed is 190 km/h. Its fuel consumption and emission values are acommendable 5.7 l/100km and134g/km respectively. The 1.2 TSI reaches its maximum power at 5,000 rpm. It has maximum torque of 175 Newton metres which is available between 1,500 and 4,100 rpm. TheJetta 1.2 TSI is mated to a 6-speed manual transmission.

1.4 TSI with 90kW
This turbocharged unit produces peak power of 90kW at 5,000 rpm and has maximum torque of 200 Nm from 1,500 up to 4,000 rpm.  It is offered with a six-speed manual transmission.

The turbocharger in this engine is designed to be compact and lightweight, giving good performance with low fuel consumption and emissions.

With a combined fuel consumption of 6.2 l/100 km (138 g/km CO2), this engine is one of the most fuel-efficient cars in its class. It has a top speed of 202 km/h and it handles the classic 0-100 km/h sprint in 9.8 seconds.

1.4 TSI with118kW
This 1.4 TSI unit uses supercharging and turbocharging to produce an impressive 118kW at 5,800 rpm and 240 Nmof torque from 1,500 to 4,000 rpm.  It is available with a six-speed manual transmission.  Its average fuel consumption is 6.3 l/100km and the CO2 emissions value is 145 g/km.

With this engine, the new Jetta sprints to 100 km/h in 8.3 seconds; its top speed is 221km/h. Especially interesting is the complementary interaction of supercharger and turbocharger. The supercharger, mechanically driven by a belt, increases the TSI’s torque at low engine speeds. This is a charging unit based on the Roots Principle. A special aspect of this supercharger is its internal gearing, which enables high supercharger performance even at low engine speeds.

At higher engine speeds, the exhaust gas-driven turbocharger (with wastegate control) kicks in. Then the supercharger and turbocharger work in series. The supercharger is operated via a solenoid clutch that is integrated in a module within the water pump. A control gate ensures that the flow of fresh air required for the operating point reaches the turbocharger or supercharger. In pure turbocharger mode the control gate is open. Then the air takes the familiar path of conventional turbocharged engines via the front intercooler and throttle valve and into the induction pipe. Starting at an engine speed of 3,500 rpm the superchargerturns all of the work over to the turbocharger.

Diesel engines

The new Jettadiesel engines usecommon rail technology which ensures that they are frugal, clean and refined.

1.6 TDI with 77kW
The entry-level TDI is a 1.6-litre unit developing 77kW. It is available with a five-speed manual or seven-speed DSG transmission.

Key features of this common rail engine are good acoustic qualities, performance throughout the rev range and extremely low levels of fuel consumption and emissions. Its power output of 77kWis reached at 4,400 rpm with maximum torque of 250 Nm from 1,500 to 2,500 rpm.  It can sprint to100km/h from standstill in 11.7 seconds and has a top speed of 190km/h.  Frugal fuel consumption is its main attribute with a combined consumption of 4.5 l/100km (4.7 l/100km for DSG) and CO2emissions of 119 g/km (123 g/km for DSG).

2.0 TDI with 103kW
The Jetta 2.0 TDI engine produces 103kW at 4,200 rpm and 320 Nmof torque from 1,750 to 2,500 rpm. It is available with a six-speed manual transmission.

It only takes 9.5 seconds from zero to 100km/h of 9.5 seconds and has a top speed of 210 km/h.  Fuel consumption remains impressive with a combined figure of 4.8litres per 100km and CO2 emissions of 126 g/km.

Transmissions

Five- and six-speed manual
The 1.6 TDI 77kW Jetta comes with a standard five-speed manual transmission.  Other manual models have a six-speed transmission featuring a magnesium selector housing and cable operation with very short lever movements.  Three-cone synchromesh for the lower gears ensures a pleasant shift action.  Reduced-friction bearings further increase the efficiency of the unit and cut fuel consumption.

All gearboxes in the Jetta are filled with lifetime oil and require no routine maintenance.

Seven-speed DSG
The Jetta 1.6 TDI is available with an optional seven-speed DSG transmission.  In adopting seven-speeds, Volkswagen engineers were able to lower first gear to improve acceleration from a standstill.  By contrast seventh gear has been raised to act as an overdrive function making it ideal for highway driving with the additional effect of further improving economy and comfort levels.

RUNNING GEAR

In designing the Jetta’s chassis, engineers set out to find a good combination of driving dynamics and comfort.  At the front the Jetta uses McPherson strut-type suspension with coil springs and telescoping shock absorbers, while at the rear there is a multi-link system with independent wheel suspension, gas dampers and separate springs.  Anti-roll bars front and rear contribute towards the car’s dynamic handling and performance.

The Jetta has a wide track (1,535 mm front, 1,532 mm rear) and a turning circle of 11.1 metres.

Electro-mechanical power steering
Like the previous generation, the Jetta benefits from an electro-mechanical power steering system.  Unlike some similar steering systems, the Jetta’s is able to vary the steering feel to suit the speed and driving situation: firm and direct when driving hard, effortless at parking speeds.  Other advantages of the system include its mild self-centring action, its ability to compensate for different driving hazards such as crosswinds and steep road cambers, and a beneficial effect on fuel economy.

Braking system
All Jettas have disc brakes all round, with ventilated discs at the front.  Lower powered models have 280 mm diameter at the front and 272 rear; while higher powered models have 288 mm diameter front discs and 272 mm at the rear.

Standard equipment on all Jettas is Volkswagen’s Electronic Stabilisation Programme with counter steering support and trailer stabilisation, which includes an anti-lock braking system (ABS), electronic differential lock (EDL), traction control (ASR) and Hydraulic Brake Assist (HBA).

Electronic Stabilisation Programme (ESP) with counter-steering support and trailer stabilisation

Essentially, ESP is a sophisticated system that automatically senses any tendency for the car to slide.  Should this situation occur, ESP reacts by applying the brakes to one, two, three or all four wheels and adjusts the engine’s power.  In this way, it is possible that a skid is corrected even before the driver is aware that one has started.

This can be useful if a tendency to understeer or oversteer develops in a bend.  In such circumstances ESP can help prevent the car skidding or spinning off the road and is particularly helpful in wet or icy conditions.

The latest generation of ESP fitted to the Jetta has a finer response, counter-steering recommendation and offers trailer stabilisation.

When the onset of yawing of a trailer is detected by the ESP control module the system automatically reduces or cuts engine power and applies the brakes to appropriate wheels dynamically in phase with the yawing to oppose the snaking motion and stabilise the vehicle/trailer combination.  When stability is achieved the brakes and engine power return to normal control.  During the automatic braking process the brake lights are turned on even though the driver may not be touching the brake pedal.

Hydraulic Brake Assist – HBA
Working in conjunction with the other elements of the braking system, this latest form of HBA recognises from the speed at which the brake pedal is depressed whether it is a ‘normal’ braking situation or an emergency stop.  In the event of an emergency stop, HBA increases braking pressure, activating ABS and ensuring the level of braking meets the needs of the conditions.  The application of brake assist makes it possible even for unskilled drivers to reduce braking distances by around 25 per cent.

Hill hold control
All Jettas have hill hold control as a standard feature.  The system is useful when the car stops for short periods such as in heavy town traffic or on a long incline.  The parking brake now comes on automatically whenever the vehicle is brought to rest preventing the car from rolling forwards or backwards for around three seconds.
