Nissan Dayz

Nissan Dayz: Which Version Should You Buy?

The Nissan Dayz in this catalogue is a Mini 5-doors model offered from June 2013 through February 2019. Although the data lists two production phases, both belong to the first generation: the original model ran from June 2013 to September 2015, followed by a restyling from October 2015 to February 2019.

The Nissan Dayz in this catalogue is a Mini 5-doors model offered from June 2013 through February 2019. Although the data lists two production phases, both belong to the first generation: the original model ran from June 2013 to September 2015, followed by a restyling from October 2015 to February 2019. The key buying decision is between the 49 hp naturally aspirated 0.7 CVT and the 64 hp Turbo 0.7 CVT, then between FWD and AWD. The Turbo adds 15 hp and 42 Nm without increasing the 658 cc displacement, while the restyling mainly changes listed kerb and gross weights rather than the core engine, transmission, clearance, or tank specifications.

Nissan Dayz generations: what changed?

The original first-generation Nissan Dayz was produced from June 2013 to September 2015 as a Mini 5-doors body and has four listed versions. Every version is named 0.7 CVT, so the meaningful identifiers are output and drive: 49 hp FWD, 49 hp AWD, 64 hp Turbo FWD, and 64 hp Turbo AWD.

The first-generation restyling ran from October 2015 to February 2019, retained the Mini 5-doors body, and again offered four 0.7 CVT versions with the same power-and-drive combinations. Engine output, torque, displacement, fuel specification, gearbox, ground clearance, and fuel-tank capacity are unchanged in the supplied figures. Kerb weight increased by 10 kg for the 49 hp FWD version, 20 kg for the 49 hp AWD version, 20 kg for the 64 hp Turbo FWD version, and 20 kg for the 64 hp Turbo AWD version. Gross weight rose by the same amount in each corresponding comparison.

This means the restyling does not buy stronger catalogue performance on paper. Its 49 hp versions still produce 56 Nm, and its Turbo versions still produce 64 hp and 98 Nm. Based strictly on the supplied specifications, buyers prioritising the lowest weight should start with the original generation, while those considering the restyling should not expect additional engine output.

Nissan Dayz engine specs and version comparison

All listed 0.7 CVT versions use a 658 cc Gasoline engine with 3 Inline cylinders, 4 valves per cylinder, distributed injection (multi-point), and a Variable gearbox. The naturally aspirated engine has no boost, a compression ratio of 12, and develops 49 hp at 6500 rpm with 56 Nm at 5600 rpm. The Turbo engine has a compression ratio of 9 and produces 64 hp at 6000 rpm with 98 Nm at 3000 rpm. Every version specifies 95 fuel and a bore-and-stroke figure of 65.4 × 65.4.

The naturally aspirated engine produces about 74.5 hp per litre, while the Turbo produces about 97.3 hp per litre. The Turbo therefore provides about 22.8 more horsepower per litre. It also delivers 75% more torque than the 49 hp engine, and its 98 Nm peak arrives 2600 rpm earlier than the naturally aspirated engine’s 56 Nm peak. Those are the largest specification differences in the entire range.

Nissan Dayz performance, mpg, and economy

Acceleration from 0–100 km/h is not measured for any 0.7 CVT version. Top speed is also not measured for any version. City fuel consumption, highway fuel consumption, and combined fuel consumption are not measured throughout both production phases. CO₂ output and environmental class are not measured as well.

Because the source provides no consumption or acceleration results, the 49 hp engine cannot be claimed to be more economical, and the 64 hp Turbo cannot be assigned a specific real-world performance advantage. What can be said numerically is that the Turbo adds 30.6% more power and 75% more torque. Whether those gains justify any price difference cannot be calculated because price data is not provided.

All versions have a 30-litre fuel tank. The identical tank size does not establish identical driving range because fuel-consumption figures are not measured.

Nissan Dayz dimensions, weight, and capacity

Overall exterior dimensions and wheel sizes are not measured in the supplied data. Ground clearance is measured and is 150 mm for every 0.7 CVT version. Each version also uses an Independent, spring front suspension, a Dependent, spring rear suspension, Disc front brakes, and Drum rear brakes.

The difference between gross and kerb weight is 220 kg for every version. This is a useful comparison figure, but it should not be treated as a separately stated payload rating.

AWD adds 40 kg to each original-generation powertrain. In the restyled range, AWD adds 50 kg to the 49 hp version and 40 kg to the 64 hp Turbo version. The lightest Dayz listed is the original 49 hp FWD 0.7 CVT at 840 kg; the heaviest is the restyled 64 hp AWD 0.7 CVT at 920 kg, an 80 kg difference.

Nissan Dayz horsepower-to-weight comparison

Weight per horsepower clarifies what the stronger engine buys. Lower figures indicate that each horsepower moves less kerb weight.

The original 64 hp FWD 0.7 CVT has the strongest power-to-weight result at about 13.4 kg/hp. The restyled 49 hp AWD 0.7 CVT has the weakest result at about 18.4 kg/hp. Moving from the original 49 hp FWD version to the original 64 hp FWD version adds only 20 kg but gains 15 hp and 42 Nm. In the restyled range, the equivalent Turbo upgrade adds 30 kg while delivering the same power and torque gains.

Choosing AWD instead of FWD does not increase engine output. It adds weight and therefore slightly worsens the power-to-weight figure in every direct comparison. AWD should consequently be chosen for the drivetrain itself, not for additional horsepower, torque, clearance, or tank capacity.

Which Nissan Dayz version should you choose?

For the strongest numbers with the lowest associated kerb weight, the original-generation 64 hp FWD 0.7 CVT is the standout. It combines 64 hp and 98 Nm with an 860 kg kerb weight, giving the best listed weight-per-horsepower result. Its Turbo engine also reaches peak torque at 3000 rpm, compared with 5600 rpm for the 49 hp engine.

For AWD with the stronger engine, the original-generation 64 hp AWD 0.7 CVT is the numerically preferable choice over the restyled equivalent. Both produce 64 hp and 98 Nm, but the original weighs 900 kg rather than 920 kg. Both retain 150 mm of ground clearance and a 30-litre tank.

For minimum kerb weight, choose the original-generation 49 hp FWD 0.7 CVT at 840 kg. It is 20 kg lighter than the original 64 hp FWD version, although it gives up 15 hp and 42 Nm. No supplied fuel-consumption measurement proves that this lower-output choice uses less fuel.

For a restyled car, the 64 hp FWD 0.7 CVT offers the best power-to-weight balance at 13.8 kg/hp. The restyled 49 hp FWD version is lighter by 30 kg, but its output falls to 49 hp and 56 Nm. The restyled 64 hp AWD version should be selected only when both the Turbo output and AWD are required; at 920 kg, it is the heaviest listed version.

Price, GPS equipment, engine-oil capacity, engine-oil type, engine-number location, exterior dimensions, reliability, and problems are not measured in the provided data. The figures therefore support a clear mechanical shortlist—but not a price, equipment, maintenance, or reliability verdict.
