In an age where diesel cars are gradually becoming rare in the mass market, Tata Motors remains committed to offering solid diesel-powered options for buyers who prioritize torque, fuel efficiency, and long-distance drivability. Two such offerings in Tata’s portfolio—the Altroz Diesel and the newly launched Curvv Diesel—are creating quite a buzz, especially among those shopping under the ₹15 lakh mark.
While both vehicles promise efficiency, value, and rugged Tata build quality, they cater to slightly different buyers. One is a premium hatchback tuned for practicality and affordability, while the other is a stylish SUV-coupe with a bold stance and a more premium experience. So, which one truly deserves your money?
Let’s break it down.
1. Pricing and Variants
The Tata Altroz Diesel is priced between ₹8.99 lakh and ₹11.29 lakh (ex-showroom), making it one of the most affordable diesel cars still available in India. With on-road prices typically ranging between ₹10.5 lakh and ₹13 lakh, it comfortably fits within the ₹15 lakh budget across all trims.
The Tata Curvv Diesel, on the other hand, is more of a premium proposition. It’s priced around ₹14–15 lakh (ex-showroom), with the top diesel trims just touching the ₹15 lakh on-road ceiling in most cities. While it offers more tech and features, the pricing leaves little room for additional packages or accessories.
Verdict: If budget flexibility is limited, the Altroz offers more breathing room with its lower entry and top-end prices.
2. Powertrain and Fuel Efficiency
Altroz Diesel is powered by a 1.5-litre, 4-cylinder Revotorq engine producing 89 bhp and 200 Nm of torque. It comes mated to a 5-speed manual gearbox. Known for its linear power delivery and excellent fuel economy, the Altroz diesel returns a real-world mileage of around 20–22 kmpl, making it a strong performer for both city and highway use.
Curvv Diesel, meanwhile, uses a more powerful 1.5-litre turbocharged Kryojet engine that delivers 118 bhp and 260 Nm of torque. It comes paired with a smooth 6-speed DCT automatic transmission—an appealing choice for those looking for convenience. Real-world fuel efficiency hovers around 11–12 kmpl in the city and up to 17–18 kmpl on the highway.
Verdict: The Curvv wins on power and automatic convenience; the Altroz wins big on fuel efficiency and running cost.
3. Driving Experience
The Altroz offers a comfortable and predictable driving experience. While not particularly sporty, it handles city roads and highway cruising with ease. The steering feels well-weighted, and the suspension is tuned for comfort. The manual gearbox is smooth, though not the slickest in its segment.
The Curvv, being an SUV-coupe, offers a more planted and confident highway drive. The diesel-DCT setup makes overtakes effortless, especially thanks to its strong mid-range torque. The suspension is more mature, absorbing bumps well while maintaining high-speed stability. However, low-speed gear shifts in the DCT can feel slightly jerky in traffic.
Verdict: The Altroz is nimble and city-friendly. The Curvv is better for long drives and offers a more relaxed driving style with its automatic gearbox.
4. Features and Cabin Comfort
With its latest update, the Altroz now comes loaded with features like a 10.25-inch touchscreen infotainment system, digital driver display, wireless Android Auto and Apple CarPlay, air purifier, wireless charger, and up to 6 airbags in top trims. The cabin is well-designed, with a premium touch for its price bracket.
The Curvv pushes things further with segment-leading features such as a panoramic sunroof, 360-degree camera, JBL sound system, ambient lighting, leatherette upholstery, ventilated seats, and ADAS (advanced driver assistance systems) in top variants. The SUV-coupe silhouette also translates to a large 500-litre boot and higher ground clearance of 208 mm.
Verdict: Curvv offers more tech, luxury, and space. Altroz offers excellent features for its price but is still a hatchback at heart.
5. Practicality and Ownership
The Altroz Diesel is ideal for someone who needs a reliable city commuter with the occasional highway run. It’s easy to park, light on the wallet, and well-built. However, some owners have reported minor issues with electronics and inconsistent service experiences.
The Curvv Diesel is better suited for small families or those who travel frequently. It’s spacious, stylish, and loaded with equipment. While initial ownership feedback has been largely positive, some minor software glitches and early batch LED failures have been reported.
Verdict: Altroz is the pragmatic choice. Curvv is the lifestyle upgrade.
Final Verdict: Which One Should You Buy?
Buy the Tata Altroz Diesel if:
-
You want the most fuel-efficient diesel car under ₹15 lakh
-
You prefer a manual transmission and lower maintenance
-
You drive mostly in the city with occasional highway trips
-

Buy the Tata Curvv Diesel if:

-
You’re willing to stretch your budget for style and technology
Conclusion
Both the Tata Altroz and Curvv diesel variants cater to distinct buyer personas. The Altroz is the efficient, well-rounded hatchback that gets the job done without breaking the bank. The Curvv, on the other hand, is Tata’s bold new offering for those who want performance, tech, and standout looks—without going into Harrier or Safari territory.
If your budget is tight and your usage is urban, the Altroz makes perfect sense. But if you’re ready to invest in something future-facing and premium, the Curvv Diesel is a refreshing alternative in the under-₹15 lakh space.
