Great Performance with Low Emissions

Martorell,  14 November 2016

The new SEAT Leon’s range of engines satisfies a wide range of needs, including diesel, petrol and CNG (Compressed Natural Gas). The diesel range starts with the 90-horsepower 1.6 TDI version up to the 2.0 TDI with 184 horsepower, not forgetting the newest arrival to the range, the 115-horsepower 1.6 TDI unit.

In specific markets, the 115 horsepower 1.6 TDI unit will be available, as well as the 2.0 TDI engine with 143 horsepower. This version is also available with 110 horsepower for taxis as an estate ST model. In all cases, the engines are common rail petrol injection with excellent fuel efficiency accompanied by very low emissions.

If one is compared to the other, we see that the 1.6 TDI 90 horsepower engine - available with 5 doors, the 3-door SC and ST estate, can achieve top speeds of 180 kph, going from 0 - 100 kph in only 12.4 seconds, 12.6 seconds (5-door version) and 13 seconds (ST). This engine comes with a manual 5-speed gearbox and its average consumption stays between 4.3 and 4.6 litres per 100 km depending on the model and wheel size chosen (from 15 to 18 inches). The best thing of all is that not one of the engines surpasses 118 g/km of C02, with a minimum level of 114 g/km (3 and 5-door versions with 15 or 16-inch rims). As if that weren’t enough, the 1.6 TDI 90 horsepower unit offers great driving pleasure thanks to a high-level of torque (230 Nm) that is available from only 1,400 rpm and remains constant up to 2,750 rpm. Similarly, the engine can remain at maximum power (90 horsepower) from 2,750 up to 4,800 rpm.
The next step up is occupied by the 110 horsepower 2.0 TDI unit that can be found in the ST estate. It comes equipped with a start-stop system, a 6-speed manual gearbox with longer ratios. And its performance is certainly extraordinary, it has to be said. With a top speed of 189 kph, 0 - 100 kph, in 10.7 seconds while its average consumption is only 4.1 litres per 100 km and its C02 emissions are lower than 106 g/km. With a maximum torque of 250 Nm between 1,500 and 3,000 rpm and a maximum power output of 110 horsepower between 3,250 and 4,500 rpm, the Leon ST 2.0 TDI guarantees outstanding efficiency of use with extremely low levels of consumption and C02 emissions.

The third variant of the 1.6 TDI is the 115 horsepower unit - the most significant newest addition to the new SEAT Leon’s diesel engine range - also uses the start-stop ignition of the series. It can also be combined with the 5-door model, the 3-door SC and the ST, to which it’s necessary to add the most adventurous of the family, the ST X-Perience. The 115-horsepower 1.6 Leon TDI can therefore have either front wheel drive or 4Drive complete with the 5th generation Haldex clutch system. The 4Drive models also have rear multilink suspension. Additionally the available gearboxes are 5-speed, automatic of double-clutch DSG with 6 (4Drive) or 7 speeds. Its maximum torque is 250 Nm but in this case between 1,500 rpm and 3,250 rom, while the 115 horsepower is available between 3,250 and 4,000 rpm. Average consumption - depending on the model, wheel size and traction system - is between 4,0 and 4,3 litre's per 100km, and C02 emissions are between 105 and 115g/km of C02.

The 2.0 TDI engine, with 150 or 184 horsepower, is also available with the 5-door model, the 3-door SC, the ST, meaning there is the option of having either front wheel drive or 4Drive. Similarly, it takes the same stop-start of the series, while the driver has the option of either a manual 6-speed gearbox or a 6 or 7-speed DSG. The 150 horsepower 2.0 TDI has a constant maximum torque of 340 Nm between 1,750 and 3,000 rpm, a truly powerful response from low engine speeds. Its 150 horsepower can also be maintained between 3,500 and 4,000 rpm. Coupled with the 3-door SC model, it’s capable of achieving 0 to 100 kph in just 8.3 seconds, capable with both the DSG and the 6-speed gearbox. This acceleration from 0 to 100 kph can be achieved in 8.4 seconds with the 5-door model and 8.6 seconds with the ST versions (8.7 for the models that come with 4Drive).  Its consumption and C02 emissions of course depends on the model, transmission and wheels (from 16 to 18 inches) selected, but never surpasses 4,9 litres per km or 126g of C02 per km, including 4.3 litres per km and 110g of C02 at its best. The 7-speed DSG is available for the ST 4Drive and ST X-Perience 4Drive. The 150-horsepower Leon TDI’s top speed is between 211 and 215 kph.

The zenith of the range of engines is the 184-horsepower 2.0 TDI. With 380 Nm of maximum torque between 1,750 and 3,250 rpm, it is the definitive proof that the SEAT Leon is capable of combining ride comfort with superlative dynamism, as well as high performance expected by even the most demanding drivers. Indeed, multilink rear suspension is always the choice for the 184-horsepower 2.0 TDI Leon, regardless of drive (front wheel drive or 4Drive). Also equipped with the start-stop system of the series available with DSG or 6-speed gearbox, the 184-horsepower 2.0 TDI model can reach top speeds of 228 kph (226 kph with DSG, 224 kph with DSG and 4Drive) and goes from 0     to 100 kph in 7.4 seconds in the case of the SC, 7.5 seconds with the 5-door and 7.8 seconds in the ST.  Fitted with 17 to 19 inch rims, its average fuel consumption and C02 emissions is between 4.5 to 4,9 litres per km and from 118 g/km to 139 g/km of C02 respectively.

With regard to the petrol engines, the range of power goes from 110 to 180 horsepower, with the stand-out new addition of the new SEAT Leon being the 115-horsepower triple-cylinder 1.0 TSI. Also in the range is the 1.4 TGI that can run on CNG and produces low levels of emissions. Below the petrol engine range is outlined.

Petrol and CNG engines

  kW/PS Nm / rpm Vmax/km/h 0-100/s CO2
1.0 TSI 85/115 200 / 2000-3500 202 9.6 102
1.2 TSI 81/110 175 / 1400-4000 194 9.9 114-119
1.4 TGI 81/110 200 / 1500-3500 194 10.9 96-130
1.4 TSI 92/125 200 / 1400-4000 203 9.1 120-124
1.4 TSI 110/150 250 / 1500-3500 215 8.0 113-118
1.8 TSI 132/180 250 / 1250-5000 226 7.5 134-138

The available gearboxes, depending on the version, are manual 5 or 6 speed, as well as the double-clutch 6 or 7 speed DSG. Front wheel drive or total 4Drive with the fifth-generation Haldex clutch will also be available.

One of the great innovations of the SEAT Leon range is the arrival of the 1.0 TSI 3-cylinder engine putting out 115 horsepower. This small marvel fits the 5-door, 3-door SC and ST. It follows the current trend in engine downsizing and is equipped with direct injection, turbo compressor, intercooler, variable valve timing and stop-start system. Coupled with the manual 6-speed gearbox, the Leon 1.0 TSI consumes 4.4 litres per km with C02 emissions of 102 g/km for manual and the double-clutch, 6-speed DSG. It’s capable of accelerating from 0 to 100 kph in 9.5 seconds (the SC), 9.6 (5-door version) and 9.8 seconds (ST). It has a top speed of 202 kph and puts out no less than 200 Nm between 2,000 and 3,500 rpm. Its functionality sets an example to engine manufacturers everywhere with its low noise and absence of engine vibrations despite the absence of a balance shaft.

The 110 horsepower 1.2 TSI (available with 86 horsepower in certain markets) is found in the range combined with the 6-speed manual gearbox. 2 options are available with the 1.4; the 110-horsepower TGI can be fuelled with either petrol or natural gas (CNG) reserved for the 5-door and ST versions, and they can be ordered with both manual 6-speed gearbox and the 7-speed DSG. In terms of the 125 or 150-horsepower TSI, the 125-horsepower is available with the manual 6-speed gearbox, stop-start and it is available with any model (5 doors, SC, ST and ST X-Perience). The 150-horsepower 1.4 TSI stands out for the ACT disconnection system that is incorporated into two of the four cylinders to reduce consumption. It can be combined with a 6-speed manual gearbox or 7-speed DSG, as well as with the 5-door, ST and SC models.

The next step up is the 180 horsepower 1.8 TSI that uses direct injection. It is important to point out that, from this level of power and upwards, the SEAT Leon uses a multilink rear suspension axle. It is also worth noting that this is a car capable of reaching 226 kph and 0 - 100 can be done in 7,5 seconds. These are speeds that almost belong in the sports car category.

To conclude, highly efficient, environmentally engines with the latest in technology, such as the 1.4 litre version with ACT. All these attributes are without a doubt of exceptional performance and high quality often only seen in sport versions. And for sport, it must be mentioned that a CUPRA version of the New SEAT Leon will be available in the near future, complete with its own surprises. But that’s a story for another day.
