Under the bonnet, the new SEAT Arona will offer five different powertrains: four petrol units (TSI) with outputs ranging from 95PS (70kW) to 150PS (110kW), joined by a 90PS (66kW) CNG unit, linked to either manual or DSG dual-clutch transmissions.

All petrol engines are equipped with turbo, direct-injection technology, with three 1.0 EcoTSI options available and a larger 1.5 EcoTSI.

The 1.0 TSI 95PS (70kW) unit, linked to a five-speed manual transmission provides 175Nm of torque. The final three-cylinder unit delivers 110PS (81kW)/200Nm and is linked to either a six-speed manual or seven-speed DSG dual-clutch transmission.

The largest option in the range is the four-cylinder 1.5 EcoTSI. With an output of 150PS (110kW)/250Nm, it produces strong performance balanced with efficiency.

In addition to the petrol engine offer, the new SEAT Arona also includes a CNG version. The 1.0 TGI 90PS (66kW) unit, linked to a six-speed manual transmission provides 160Nm of torque

A CNG vehicle reduces CO₂ emissions by about 25% compared to a petrol driven equivalent. As well as ecological and tax benefits, TGI technology offers exceptionally low costs per kilometre, up to 50% cheaper than a petrol equivalent model and 30% cheaper than a diesel.

SEAT is also supporting the development and availability of renewable bio-methane, which neutralises CO₂ emissions generated through vehicle use. High quality bio-methane is obtained from organic waste residues and can either be added to conventional natural gas or used to substitute it completely. Bio-methane combines environmentally friendly mobility with the circular economy and reduces the CO₂ impact of this engine type during its lifecycle.
