Peugeot 308 GTi: Which Version Should You Buy?

The Peugeot 308 GTi catalogue data presents two power choices—250 hp and 270 hp—across the original model and its restyling. Every version is a Hatchback 5-door with a 1,598 cc Gasoline engine, a 6-speed Manual gearbox and FWD. The central buying decision is therefore not about body style, transmission or drive system, but about output, weight, fuel consumption and model period.

The Peugeot 308 GTi catalogue data presents two power choices—250 hp and 270 hp—across the original model and its restyling. Every version is a Hatchback 5-door with a 1,598 cc Gasoline engine, a 6-speed Manual gearbox and FWD. The central buying decision is therefore not about body style, transmission or drive system, but about output, weight, fuel consumption and model period. On the figures available, the original 270 hp 1.6 MT offers the strongest power-to-weight result, while the restyled 270 hp 1.6 THP MT combines the higher output with the lowest listed combined consumption. Reliability, problems, price and cars for sale are not measured in the supplied data, so they cannot decide the comparison.

Peugeot 308 GTi generations and versions

The catalogue contains one generation in two forms, not two separate generations. The original 1 generation ran from 2015 to 2017 as a Hatchback 5-door and included two versions, both named 1.6 MT: one with 250 hp and one with 270 hp.

The 1 generation, restyling started in 2017, with no stop date measured. It retained the Hatchback 5-door body and again offered two versions. Both are named 1.6 THP MT, so they must be distinguished by their 250 hp and 270 hp outputs.

That creates four exact version-and-power combinations for comparison:

• 2015–2017 1.6 MT with 250 hp
• 2015–2017 1.6 MT with 270 hp
• Restyled 1.6 THP MT with 250 hp
• Restyled 1.6 THP MT with 270 hp

Peugeot 308 GTi engine specs and horsepower

All four versions use a 1,598 cc Gasoline engine with 4 Inline cylinders, 4 valves per cylinder, Turbo boost, direct injection and a front, transverse installation. Each has a compression ratio of 11.5 and a bore and stroke of 77 × 85.8. All require 95 fuel and send power through a 6-speed Manual gearbox to FWD.

Because displacement is identical, the 270 hp engines produce about 169 hp per litre, compared with about 156 hp per litre for the 250 hp engines. Choosing 270 hp therefore adds 20 hp without increasing engine capacity.

The original 270 hp 1.6 MT increases power over the original 250 hp 1.6 MT while retaining the same 330 Nm at 1900 rpm. In the restyled range, the choice is less one-dimensional: the 270 hp 1.6 THP MT has 20 hp more, but the 250 hp 1.6 THP MT has 10 Nm more torque. That 250 hp version delivers 340 Nm at 2100 rpm, whereas the 270 hp version delivers 330 Nm at 1900 rpm.

Engine code, engine oil specification, engine-bay details, repair information, reliability and engine problems are not measured. The data consequently supports a specification comparison, but not a reliability ranking.

Peugeot 308 GTi performance, mpg and fuel consumption

The original 270 hp 1.6 MT reaches 100 km/h 0.2 seconds sooner than the original 250 hp 1.6 MT, although both have the same 250 km/h top speed and identical listed consumption. This makes the 270 hp original version the straightforward performance choice between those two.

Both restyled versions record 6 seconds to 100 km/h and 250 km/h. The extra 20 hp of the restyled 270 hp 1.6 THP MT does not produce a measured acceleration or top-speed advantage over the restyled 250 hp version in this dataset. It does, however, accompany lower listed consumption: 0.4 L/100 km less in the city, 0.4 L/100 km less on the highway and 0.5 L/100 km less combined. Its CO₂ figure is also 9 g/km lower.

Fuel economy is supplied in L/100 km; mpg is not measured. All four versions meet Euro 6.

Peugeot 308 GTi dimensions, weight and wheels

The original versions share a 1,205 kg kerb weight. This gives the 250 hp 1.6 MT about 4.82 kg per hp and the 270 hp 1.6 MT about 4.46 kg per hp. Since they weigh the same, every part of the original version’s power-to-weight advantage comes from its additional 20 hp.

The restyled 250 hp 1.6 THP MT weighs 1,390 kg, or about 5.56 kg per hp. The restyled 270 hp 1.6 THP MT is 110 kg lighter despite producing 20 hp more, giving it about 4.74 kg per hp. It is therefore the clearly stronger restyled choice by power-to-weight arithmetic.

Comparing the 270 hp cars across the model period, the original 1.6 MT is 75 kg lighter than the restyled 1.6 THP MT and has the better weight-per-horsepower figure: about 4.46 versus 4.74 kg per hp. Comparing the 250 hp cars, the original 1.6 MT is 185 kg lighter than the restyled 1.6 THP MT.

Ground clearance remains 110 mm and tank capacity remains 53 L throughout. Gross weight is measured only for the restyled versions, at 1,790 kg. Wheel sizes are measured only for the original 250 hp 1.6 MT, with 225/40 R18 and 235/35 R19 listed; the other wheel-size entries are not measured.

Which Peugeot 308 GTi version should you buy?

For the best performance-to-weight result, choose the original 270 hp 1.6 MT. It combines the highest listed output with the lowest shared kerb weight, reaches 100 km/h in 6 seconds and records the same 6 L/100 km combined consumption as the original 250 hp version. Against that 250 hp car, it adds 20 hp and cuts 0–100 km/h by 0.2 seconds without a listed fuel-consumption penalty.

For a restyled car, the 270 hp 1.6 THP MT is the numerical favourite. Compared with the restyled 250 hp 1.6 THP MT, it offers 20 hp more, weighs 110 kg less and uses 0.5 L/100 km less fuel combined. The trade-off is 10 Nm less peak torque, although its 330 Nm arrives at 1900 rpm rather than the 250 hp version’s 340 Nm at 2100 rpm.

The original 250 hp 1.6 MT remains relevant when the known wheel-size choices matter: it is the only version with wheel specifications measured in the data. Its 1,205 kg kerb weight also makes it 185 kg lighter than the restyled 250 hp car. However, the original 270 hp version has the same measured weight, economy, torque and top speed, plus 20 hp more and quicker acceleration.

No conclusion about “what the extra money buys” can be made because prices are not measured. Listings and availability for cars or engines are also not measured. On specifications alone, the original 270 hp 1.6 MT is the strongest choice for power-to-weight performance, while the restyled 270 hp 1.6 THP MT is the best choice for buyers who specifically want the restyling.
