New SEAT Ateca 2020

Powertrains and chassis: Advanced engines designed to maximise efficiency

Martorell, 14 September 2020

A range of powertrains boost efficiency whether customers chose petrol (TSI) or diesel (TDI), with each designed to deliver the highest levels of performance and driveability, while also reducing emissions, giving customers the right combination of vehicle and engine to match their needs.

But it isn’t solely about what’s under the bonnet. The SEAT Ateca’s chassis mixes technologies developed to make sure that no matter what the road throws at it, the compact SUV can take them all in its stride. Effortlessly mixing a driver focused experience, with one that maximises comfort for everyone in the cabin.

Petrol

Four petrol options are available. A three-cylinder 1.0 litre TSI unit which produces 110PS (81kW) of power and 200Nm of torque and linked to a manual transmission. This engine uses a Miller-cycle combustion process and variable geometry turbocharger to take efficiency to the next level in this displacement size engine.

The Miller-cycle optimises valvetrain control with early closure of the inlets combined with a higher compression rate and turbocharging to better control the air-fuel mixture, to improve efficiency by up to 10%.

Available with a power output of 150PS (110kW) and 250Nm of torque the larger capacity four-cylinder 1.5 litre petrol engine is available with both manual and DSG dual-clutch transmissions. It integrates Active Cylinder Management, so in some driving scenarios the engine works with only two cylinders to reduce the fuel consumption and maximise efficiency.

The most powerful petrol option is a 190PS (140kW) 2.0 litre TSI unit with a higher torque of 320Nm, linked exclusively to a DSG dual-clutch transmission and 4Drive all-wheel drive system.

Diesel

Diesel remains a key technology in the Ateca’s powertrain line-up, and with the introduction of the new version of the Ateca, the offering has been adjusted to provide a greater balance between dynamism and efficiency.

All TDI units introduce a new twin dosing SCR system that includes dual AdBlue injection to reduce significantly NOx emissions compared to previous generation diesel engines. The result is a range of diesel engines that meet the strict requirement of Euro 6AP emissions standards.

The 1.6 litre TDI units that were previously available with the lower output (115PS/85kW) have been replaced with 2.0 litre TDI engines; in addition to offering better performance (more torque and maximum power available in a wider range of engine speeds), the 2.0 TDI allows for significant emission reduction.

The line-up includes a 2.0 linked engine linked to a six-speed manual transmission with a power output of 115PS (85kW) and 300Nm of torque.

A more powerful 150PS (110kW) unit with 340Nm of torque is available, linked to either a manual or DSG dual-clutch transmission. The 150PS (110kW) unit is also available with 4Drive all-wheel drive (exclusively with the DSG transmission); in that case, maximum torque is 360Nm.

The performance and efficiency of the powertrains is matched by the chassis, allowing the new SEAT Ateca to offer an involved, dynamic drive no matter what the conditions.

At the front, the Ateca uses MacPherson struts while at the rear a semi-rigid axle or a multilink axle (only for 4Drive versions) setup specifically to match the powertrain choice gives the dynamic performance needed to make sure whether you are through town, along motorways or on twisting country roads, the compact SUV is assured and builds driver confidence.

And for those models with DCC Dynamic Chassis Control, the vehicle’s ride and handling can change depending on the conditions and the driver’s requirements, making the vehicle more comfortable.

The adaptive chassis technology constantly reads the road conditions, while also considering steering input, braking and acceleration, to adapt the suspension, optimising damping at each wheel to provide comfort and dynamics like no other.

On front wheel variants with the system, drivers can select from Eco, Normal, Sport and Individual options using the rotary dial, while for vehicles that include 4Drive all-wheel drive two more options – Offroad and Snow – are also available.

Front-wheel drive versions of the Ateca offer an incredible driving experience, but the 4Drive system brings with it’s a host of additional benefits, adding a level of assurance to the drive in more challenging conditions.

As one of the most advanced all-wheel drive systems, 4Drive is located on the rear multilink axle at the end of the drive shaft, just in front of the rear differential. This positioning improves weight distribution reduces inertia and system reaction time since the cardan shaft is always connected to the engine.

The multi-disk wet clutch’s metal friction rings are placed in pairs one in front of the other: one ring of each pair is permanently connected to the drive shaft that turns with the gearbox; The other ring turns with the driveshaft joined to the rear axle’s differential. A hydraulic actuation piston compresses the multi-disk packet to reach the required oil pressure, depending on the parameters indicated by the electronic system.

Combined with the precise, responsive electric power assisted steering and the choice of a quick shifting DSG dual-clutch transmission or precise six-speed manual gearbox, the new SEAT Ateca offers an exquisite mix of driver focused ability and refined composure on the road.
