Scirocco -  Engines and Transmissions

Volkswagen will be offering the Scirocco as the first sports car in the world to have a full lineup of charged four cylinder engines. The three TSI gasoline direct injection engines output 90 kW / 122 PS, 118 kW / 160 PS and 147 kW / 200 PS. The TDI – a highly advanced common rail turbo-diesel – develops 103 kW / 140 PS. In the coming year, another TDI will follow that delivers 125 kW / 170 PS of power. All of the Sciroccos come with a standard manual 6-speed transmission. Engine versions 140 PS and higher can be ordered with an optional dual clutch transmission (6 or 7-speed DSG) that is as sporty as it is efficient.


TSI – GASOLINE ENGINES OF THE SCIROCCO

TSI with 90 kW / 122 PS

Maximum power with minimum fuel consumption – that is the property of the TSI four cylinder engines that has become synonymous with a new generation of economical and simultaneously sporty Volks­wagen engines in just a short period of time. The entry-level Scirocco engine clearly demonstrates why: its average consumption of 6.1 liters super unleaded per 100 kilometers and conformance to the future Euro-5 emissions standard* makes it one of the most economical and cleanest engines of its class. The 122-PS TSI is capable of a top speed of 200 km/h. This Scirocco puts the classic 0-100 km/h sprint behind it in 9.7 seconds.

The highly acclaimed engine represents the entry level into the TSI world with its 90 kW / 122 PS (at 5,000 rpm). Thanks to its turbocharger, the torque-strong gasoline engine complements the sports car's character. In the Scirocco, the four cylinder engine develops its maximum torque of 200 Newton-meter between 1,500 and 4,000 rpm; in addition, 80 percent of its maximum torque is available at just 1,250 rpm.

Technically speaking, gasoline direct injection, charging and reduced engine displacement are among the most efficient methods for significantly reducing fuel consumption while improving vehicle dynamic properties just as distinctly. That is why Volkswagen is taking precisely this approach on its TSI engines: low specific fuel consumption and better efficiency are attained by reducing engine displacement with lower friction and charge exchange losses. Charging is performed – depending on the power class – either by a combination of turbocharger and supercharger or, as on the 122-PS TSI, with the help of a specially developed turbocharger.

TSI with 118 kW / 160 PS

This is the latest TSI: a four cylinder charged by turbocharger and supercharger that outputs 118 kW / 160 PS (at 5,900 rpm). Interesting here is a look at its specific power. The 1.4 liter engine achieves 84.3 kW, or 114.3 PS, per liter displacement. Like all TSIs, this engine is also exceptionally economical (average consumption: 6.5 liter super unleaded per 100 kilometers) and torque strong (maximum of 240 Newton-meter at just 1,750 rpm). In this case, the high torque maximum is continuously available up to 4,500 rpm. Similar to the 122-PS TSI, the 160-PS version also already satisfies the future Euro-5 emissions standard*.

The Scirocco TSI, with its 118 kW, reaches the 100 km/h mark from a stop after just 8.0 seconds; its top speed is 218 km/h. Optionally, the 160-PS TSI can be combined with the world's first transverse-mounted 7-speed DSG dual clutch transmission.

Especially interesting from a technical perspective are the complementary modes of operation of the supercharger and turbocharger. The supercharger – mechanically driven by a belt – boosts the TSI's torque at low engine speeds. In this case, the charger unit is based on the Roots Principle. A special feature of the supercharger that is used is its internal gear ratio, which enables high supercharger power boost at low engine rpms.

At elevated engine speeds the turbocharger (with wastegate control) kicks in. The supercharger and turbocharger operate in series here. The supercharger is actuated by a magnetic clutch integrated in a module within the water pump. A control flap ensures that the fresh air needed for the specific operating point is fed to the turbocharger or supercharger. In pure turbocharger operation the control flap is open. Then the air travels the conventional route of turbo engines via the front intercooler and throttle to the exhaust pipe. Starting at an engine speed of 3,500 rpm the supercharger turns all of the work over to the turbocharger.

TSI with 147 kW / 200 PS

At the highest performance level, a powerful 147 kW / 200 PS (5,100 to 6,000 rpm) TSI is used in the Scirocco. On the 2.0 liter engine that is designed even more for maximum dynamics, a larger turbocharger inhales steam furiously. It can be said in general that this TSI also shines with very good torque and fuel economy values. The 280 Newton-meter (from 1,700 to 5,000 rpm) torque-strong four cylinder consumes just 7.7 liters of fuel per 100 kilometers. Nonetheless, it still delivers a top speed of 235 km/h. The strongest Scirocco of all times handles the sprint to 100 km/h in 7.2 seconds. Just as on the Golf GTI with the same engine, on the Scirocco too this engine can be ordered with an innovative 6-speed dual clutch transmission.


TDI –DIESEL ENGINES OF THE SCIROCCO

TDI with 103 kW / 140 PS

A clean and torque-strong 140-PS TDI (103 kW at 4,200 rpm) will be available on the Scirocco at the time of its market launch in Europe. The highly advanced common rail diesel is especially quiet. It already develops its maximum torque of 320 Newton-meters at a low 1,750 rpm. The Scirocco completes the 0-100 km/h sprint in just 9.3 seconds with this TDI. Its top speed of 207 km/h contrasts with average fuel consumption of just 5.4 liters per 100 kilometers. Like the 1.4 liter TSI, the TDI will already fulfill the Euro-5 emissions standard*. Offered as an option with the TDI is 6-speed DSG.

Fuel induction in the TDI is handled by the latest generation common rail system. Up to 1,800 bar injection pressure and special eight-hole injection nozzles produce extremely fine atomization of the diesel fuel.

The latest generation of piezo in-line injectors handles control of the eight-hole injection nozzles. The electrically controllable piezo crystals trigger the injection in just fractions of a second with the support of a hydraulic element. Compared to conventional solenoid valves, piezo technology enables more flexible injection processes involving smaller and more precisely metered amounts of fuel. The advantage: very quiet and pleasantly gentle engine running, exceptionally spontaneous response behavior and low fuel consumption and emissions values. The crankshaft's toothed belt drive, which is completely maintenance-free, also has a positive effect on acoustics. In the upcoming year, a TDI with 125 kW / 170 PS that utilizes the same technical basis will follow.


DSG –AUTOMATIC TRANSMISSION OF THE SCIROCCO

6 and 7-speed DSG dual clutch transmission

The new Scirocco is offered with a 7-speed DSG (160-PS TSI) and a 6-speed DSG (140-PS TDI and 200-PS TSI). Both automatic transmissions are characterized by maximum economy and gear shifting dynamics previously unattainable in this form. New in the transmission lineup is a 7-speed DSG with two dry clutches; the dual clutch of the 6-speed DSG runs wet in an oil bath. This is true of both transmissions: the most practiced drivers cannot even approach the shifting speed of the DSG versions. Another fact: more than any other automatic, the dual clutch transmissions have the potential to reduce fuel consumption and in turn emissions. Depending on the engine, this savings can amount to up to twelve percent compared to a manual transmission, and compared to an automatic with lock-up torque converter it may even reach twenty percent.

Both DSG variants are specialists in their applications. While the 6-speed DSG, thanks to its torque characteristic, is particularly brilliant when paired with large, torque-strong engines (up to 350 Newton-meter), the 7-speed DSG is especially recommended in tandem with smaller engines (up to 250 Newton-meter).
