Seat Leon: Fuel-Efficient Sedan Or Gas Guzzler?

The SEAT Leon is a family hatchback that comes in petrol, diesel, mild-hybrid and plug-in hybrid versions. The diesel models are the most economical and the 1.6 TDI model has an official combined result of 70.6mpg and CO2 emissions of 105g/km. The petrol models are slightly less economical with the 1.5 TSI 130 model having an official combined result of 52.7mpg.

SEAT Leon 1.6 TDI - official combined result of 70.6mpg

The SEAT Leon 1.6 TDI is a diesel car that offers decent economy figures with an official combined result of 70.6mpg and CO2 emissions that dip down to 105g/km. This is better than many of the best-performing superminis can muster, and while real-world driving is likely to deliver economy in the 60s, that’s still pleasingly parsimonious in a family hatchback of this size.

The SEAT Leon range does well when it comes to fuel economy. Diesels may be falling out of fashion, but they’re still the most economical way to run a SEAT Leon if you don’t want to choose the plug-in hybrid.

SEAT Leon 1.0-litre petrol - 0-62mph in 10.8 seconds

The SEAT Leon is a family hatchback that comes in petrol, diesel, mild-hybrid and plug-in hybrid options. The entry-level engine is a 109bhp 1.0-litre petrol (badged TSI 110). It pulls well enough from low revs and doesn’t struggle to keep up with faster-moving traffic, with 0-62mph taking a respectable 10.8 seconds.

The 128bhp 1.5-litre TSI 130 petrol is preferred because it offers considerably more punch, with a 0-62mph time of 9.4 seconds. In fact, it’s good enough to negate the need for the more expensive 148bhp version of the same 1.5-litre engine. Versions with an automatic gearbox use mild-hybrid versions of the 1.0 and 1.5 petrol engines (1.0 eTSI 110 and 1.5 eTSI 150), and you’ll notice very little difference in economy between these and their non-hybrid counterparts.

SEAT Leon 1.5-litre TSI 130 - 0-62mph in 9.4 seconds

The SEAT Leon is a family hatchback that comes in petrol, diesel, mild-hybrid and plug-in hybrid versions. The 1.5-litre TSI 130 petrol engine is economical and significantly cheaper than the more powerful 1.5 TSI 150. It offers considerably more punch than the entry-level 1.0-litre petrol engine, with a 0-62mph time of 9.4 seconds.

The SEAT Leon range does well when it comes to fuel economy. Diesels are the most economical way to run a SEAT Leon if you don’t want to choose the plug-in hybrid. The 1.6 TDI diesel engine has an official combined result of 70.6mpg and CO2 emissions that dip down to 105g/km.

The 1.5-litre TSI 130 engine is priced below the Ford Focus and VW Golf when you’re comparing like-for-like versions. A Skoda Octavia will cost a similar amount, but the Skoda Scala is a fair bit cheaper.

The mild-hybrid e-TSIs are expensive compared with manual cars and fuel economy isn’t that impressive. Versions with an automatic gearbox use mild-hybrid versions of the 1.0 and 1.5 petrol engines (1.0 eTSI 110 and 1.5 eTSI 150), and you’ll notice very little difference in economy between these and their non-hybrid counterparts.
