An engine that proves size no longer matters could soon open new doors for Volkswagen’s Spanish brand.

Providing 1.6-litre-level power with low tailpipe emissions and high operating economy, the German group’s smallest turbocharged petrol motor is claimed to have all it takes to win new business with fleets.

“What we have here is a great opportunity for growth – the promise of good economy without the loss of driving performance means this engine has a lot of potential,” Seat national fleet sales manager Sally Livingstone said.

Despite using direct injection and reduced internal friction levels to match the 105bhp output of the 1.6-litre engine it supplants, the new 1.2-litre TSI unit also draws on stop-start and brake energy recovery systems for a significant lift in economy with a potential of more than 55mpg along with CO2 emissions of just 119g/km.

On course to be the Volkswagen’s most-produced small displacement petrol engine, it feels noticeably more dynamic than its 400cc larger predecessor and the statistics prove it with 129lb-ft maximum torque being developed at only 1,500 revs, compared with 109lb-ft from the 1.6-litre engine at 3,800 rpm.

Now wearing Ecomotive badges in standard trim with a five-speed manual gearbox, the new powertrain adds the bonus of the latest seven-speed DSG unit as a £450 option – less than half the option cost listed for the discontinued 1.6-litre model.

“With emissions below the crucial 120g/km level and the convenience of variable servicing, this engine is an attractive proposition in a fleet and business context,” said Livingstone.

Verdict

With a blend of crisp performance and high efficiency, the new TSI offers practicality in an attractive package that has sporty appeal.
