Which new Mahindra XUV300 is better: diesel or petrol?

The Mahindra XUV300 has proven itself as a competent compact crossover in a heavily competitive segment with rivals from all the high-volume automakers. Let us compare the two and determine which is better, petrol or diesel.

Buying a Car

Compact crossovers are increasing with popularity as consumers find their raised ride height and pseudo-SUV styling combined with hatchback-like manoeuvrability and ease of use appealing. The XUV was not only the first within the segment for Mahindra, but it also signalled a new design direction for the brand, with a far more palatable approach to aesthetics. Join us as we compare the two models within the range to determine which is best, the petrol or the diesel.

The figures

Five models, two engines

The local XUV300 range consists of five models, three fitted with the diesel engine and two with the turbocharged petrol. For this comparison, we have selected the top-spec W8 models in both petrol and diesel guise. They make for an interesting and relevant comparison as both are similarly priced, both feature small capacity engines, the same 6-speed manual gearbox and are near identical in terms of standard specification.

The petrol

The petrol engine in the XUV300 range is a turbocharged 1.2-litre three-cylinder unit that produces 81kW of power at 5 000r/min and 200Nm of torque between 2 000-3 500r/min which is sent to the front wheels via a 6-speed manual gearbox. Claimed fuel consumption is an admirable 6.1 L/100km while an official 0-100km/h sprint time is not quoted; however, we feel as though that unnecessary in a vehicle like this in any case.

The diesel

The 1.5-litre turbodiesel in the XUV300 produces some impressive figures for its displacement, with 86kW of power at 3 750r/min and a meaty 300Nm of torque available between 1 500-2 500r/min. The diesel features the same 6-speed manual gearbox which also sends power to the front wheels; however, the diesel is notably lighter on fuel, with a claimed figure of 4.8L/100km.

Analysis

Looking at the figures, the only areas in which the petrol model appears to be superior to the diesel is in its lower initial cost price and in its kerb weight. If we look at the power and torque figures, the diesel has its power and torque available lower in the rev range (mainly because diesel engines do not rev as high as petrol motors), is markedly lighter on fuel and provides nearly 200km more driving range on a single tank.

Verdict

Having viewed the figures, the diesel model within the XUV line-up is the most efficient while offering the most power and torque, however, the petrol model is some R20 000 less when new and is 52kg lighter. The R20 000 price discrepancy means little when a monthly instalment scenario is considered, meaning that the diesel will be the cheaper car to run, will provide more driving range on a single tank and is likely to match the petrol in terms of acceleration, handing it the victory in today’s comparison.

It’s now reached the point where the vast majority of new diesel-powered vehicles are bakkies, SUVs and high-end sedans, while diesel power in budget-conscious offerings are gradually being phased out. There are still some lower-priced diesels on the market, though, and we’ve combed the lists to find those new and used diesels on offer.Mahindra XUV300 finally arrives in South Africa24 May 2019|AutoTraderMahindra XUV300 finally arrives in South AfricaMahindra XUV300 finally arrives in South AfricaMahindra XUV300: We drive it first in India06 Feb 2019|AutoTraderMahindra XUV300: We drive it first in IndiaMahindra XUV300: We drive it first in IndiaHow much are car repayments on a new Mahindra KUV100 Nxt?15 Mar 2021|Ryno FourieHow much are car repayments on a new Mahindra KUV100 Nxt?The Mahindra KUV100 Nxt is offered in eight derivatives, all of which come in under R250 000.
