In such situations, a car's safety technology matters as much as good headlights and steady hands on the wheel. This is where radar-based ADAS have a clear advantage over camera-only systems.
Unlike cameras, which rely on visible light and struggle in fog, radar uses radio waves that can pass through fog and moisture. Sensors continuously measure the distance and speed of oncoming vehicles, feeding this data to systems like adaptive cruise control and automatic emergency braking. While ADAS is never a substitute for driver attention, radar-assisted systems remain more reliable when visibility is poor.
Here are five cars sold in India with radar-based Level 2 ADAS that can make driving in dense fog a little less stressful:
The newly launched Tata Sierra enters the mid-size SUV segment with a focus on safety and technology. The Sierra is equipped with Level 2 ADAS, which includes adaptive cruise control, autonomous emergency braking, and lane keep assist functions that rely on radar and camera fusion.
Engine options include petrol and diesel units, with the power figure going up to around 158 bhp depending on the variant. Sierra is priced below Harrier From Rs 11.49 Lakh Rs 21.29 lakh (ex-showroom). With its high seating position and modern safety technology, the Sierra is targeted at buyers who want everyday utility with added confidence in poor visibility.
Kia has recently unveiled its new generation Seltos. However, the variants sold earlier also came packing the Level 2 ADAS suite. Higher variants get radar-assisted features including adaptive cruise control, forward collision avoidance and lane keeping system.
The highlight is the 1.5-litre turbo-petrol engine that produces around 157 bhp, while a naturally aspirated petrol option is also available. Prices range from from 10.8 lakhs Rs 19.8 lakh (ex-showroom). For highway commuters who often encounter fog while driving early in the morning, the Seltos' ADAS package adds a reassuring safety net.
Hyundai's Creta remains a benchmark in the SUV sector, and its SmartSense ADAS suite cements that position. This system combines radar and cameras to enable adaptive cruise control, lane keeping assist, and automatic emergency braking.
The Creta is offered with multiple powertrains, including a 1.5-litre turbo-petrol engine producing around 157 bhp. Ex-showroom prices currently sit between 10.7 lakh more 20.2 lakh. In dense fog, the Creta's radar-based distance monitoring works quietly in the background, stepping in only when needed.
The XUV700 was one of the first mass-market Indian SUVs to offer radar-based Level 2 ADAS, and it remains one of the most widely implemented in its price range.
The petrol version of this SUV produces around 197 bhp, while the diesel goes up to around 182 bhp, making it one of the most powerful cars on this list. XUV700 prices range from from 13.6 lakhs Rs 23.7 lakh (ex-showroom). Features like Smart Pilot Assist and emergency braking are especially useful on foggy expressways where sudden deceleration is common.
Radar-based ADAS is no longer limited to SUVs, and the Hyundai Verna proves that point. The sedan gets radar-assisted SmartSense ADAS on higher trims, which includes adaptive cruise control and forward collision warning.
Its 1.5-litre turbo-petrol engine produces around 157 bhp, making the Verna one of the fastest cars in its segment. With prices starting from Going up to Rs 10.7 lakh and Rs 16.9 lakh (ex-showroom), it offers radar-based safety technology in a lower, more aerodynamic body style.
conclusion
Radar-based ADAS does not magically eliminate the risks of driving in fog, and it does not replace careful driving. But when visibility is reduced and reaction time matters, radar gives the car a more reliable way to “see” what's going to happen ahead. For Indian conditions, especially winter highways, these systems can make a meaningful difference when used responsibly to help avoid accidents.
