Hyundai Venue

Since your monthly running is on the higher side, a diesel SUV would make sense. The newly updated Hyundai Venue in HX 5 trim would fit in your budget and is a big upgrade from the WagonR. The engine is refined, frugal and tried and tested, and should you get the manual gearbox, it has a light clutch that makes it easy in traffic. 

The HX 5 also gets a good level of kit, like a sunroof, cruise control, touchscreen, reversing sensors, TPMS, etc. The ride quality is good too, and it has a decent-sized boot for outstation trips. 
Hyundai's after-sales network is also one of the best, and it would be a hassle-free ownership experience. 

Without knowing your budget and more requirements, we can't recommend the ideal choice for you. We have shortlisted models that you should consider, and why they are of interest. 

Compact SUVs
- Hyundai Venue: (+) Smooth diesel engine and auto gearbox combo, good interior space, upmarket interior | (-) Expensive for its size
- Kia Sonet: (+) Smooth diesel engine and auto gearbox combo, upmarket interior, good value | (-) Rear seat space is limited, due to be replaced in the coming year

Midsize SUVs

- Kia Seltos: (+) Spacious interior, well equipped, good ride comfort | (-) Performance is adequate only
- Tata Sierra: (+) Class-best space, feature-packed, tough build, ride comfort | (-) Engine feels noisy, road noise
- Hyundai Creta: (+) Well equipped, decent performance | (-) Due to be replaced in the coming year   

   

While the Tata Nexon has its strengths in a tough build and good suspension, its AMT gearbox is no match for the torque converter automatic. It comes paired with the Hyundai Venue and Kia Sonet's 1.5-litre diesel engine. The Hyundai and Kia's smooth diesel engines and slick auto gearboxes deliver a very polished driving experience, which you will love. 

Of the two, the Hyundai Venue is newer, offers more rear seat space and a few more frills like a larger 10.25-inch touchscreen. You'd get a Venue diesel-auto HX5 in your budget, which is reasonably well equipped and also packs in a sunroof. We can't recommend it wholeheartedly, though, because it misses the safety of a rear wiper. 

If rear seat space isn't a deal breaker and you are comfortable with the idea of buying a car that will be replaced in the near future, the Sonet diesel-auto HTX is definitely worth a look. 

For not much money over the Venue HX5, it packs in a whole lot more equipment such as LED headlights, push button start, leatherette seats and front seat ventilation. Also, it has the safety of a rear wiper, rear disc brakes and front parking sensors.  

While the Mahindra XUV 3XO has a strong and refined engine, the AMT gearbox is not the best performing units in terms of smoothness and response. Quick overtakes on the highway would require a lot more planning with an AMT, and over time, it can get frustrating. 

We would recommend checking out the Hyundai Venue as it gets a diesel engine mated to a 6-speed torque converter gearbox that is a lot better than AMT units. The Venue is also well equipped in its HX5 guise that falls within your budget. It is the newer car overall with a fresh and modern interior. 

For the kind of usage you describe, around 178km a day and roughly 46,000km a year - a diesel car makes far more sense than a CNG one.
Firstly, diesel is much more widely available on highways and expressways, which is where you’ll be spending most of your time. With such high daily mileage, convenience matters, and diesel fuel stations are easy to find almost anywhere in the country.

Secondly, diesel engines are better suited to long-distance cruising. Their strong low-end and mid-range torque make overtaking easier and allow the car to cruise at highway speeds with less effort. This also typically results in lower engine stress and more relaxed driving.  It should suit your priorities of smooth cruising, good NVH and long-term durability.

CNG cars, on the other hand, do have a few compromises. Performance is noticeably weaker than petrol versions, because CNG produces less energy. When the car is fully loaded or when you need quick overtakes on the highway, the lack of power becomes quite evident. 

Another practical issue is that the CNG cylinder takes up a large portion of the boot, which can be inconvenient if you are frequently travelling with luggage. From a mechanical perspective, modern factory-fitted CNG engines are much better engineered than earlier conversions. 

However, CNG is a dry gaseous fuel and doesn’t have the lubricating properties of liquid fuels, so over very high mileages, there can be slightly higher wear on valves and valve seats. For someone covering well over 40,000km a year, a diesel powertrain is generally the more robust long-term solution.

Since you haven’t mentioned your exact budget, here are a few strong diesel options across segments. In the compact SUV class, the Hyundai Venue diesel is a good choice with a refined and proven 1.5-litre engine. If you want something larger and more comfortable for long highway drives, the Hyundai Creta diesel remains one of the best all-rounders with excellent refinement and efficiency. 

And if you are looking for something bigger and more premium, the Mahindra XUV7XO diesel offers strong performance, good highway manners and a very robust engine.

Both Hyundai Motor India and Mahindra & Mahindra have well-proven diesel engines that are known to handle high mileage well when properly maintained. Given your driving pattern and ownership horizon of 5 years or more, diesel is clearly the more suitable and practical choice.

Since your running is on the higher side and you prioritise fuel efficiency, a diesel compact SUV would be a suitable pick. Our recommendation would be the new Hyundai Venue in HX5 trim with the 1.5-litre diesel and 6-speed manual combination, which sits within your budget. The engine is refined for a diesel, has adequate performance for your highway journeys and delivers good fuel efficiency too, with an ARAI rating of 20.99kpl. In the real world, you can expect efficiency in the mid- to high-teens on the highway.

The HX5 trim is well equipped with features like dual displays with a 10.25-inch infotainment system, a sunroof and cruise control, which will be useful on your drives from Dehradun to Haridwar. Finally, as you want to keep the car for almost 10 years, reliability and service are important, and Hyundai is well known for both. Do take a test drive before you decide.
