Level 2 ADAS is now a ₹7 lakh feature: what the Glanza, Elevate and Bayon actually give you, and how it copes with Indian roads

Three years ago, Level 2 driver assistance in India meant an MG Astor or a top-spec Hyundai Verna. This month it arrived in a hatchback that starts at ₹6.99 lakh. The new Toyota Glanza, the facelifted Honda Elevate and the Hyundai Bayon all launched in October 2026 with adaptive cruise control, lane keeping and autonomous emergency braking somewhere in their variant walk. The feature has crossed from luxury to mainstream in a single festive season. Here is what you are actually buying, how it is built, and why some of it will annoy you on Indian roads.

What "Level 2" means, in plain terms

The industry uses a six-step scale from Level 0 (no assistance) to Level 5 (no driver). Level 2 is the highest level where the human remains fully responsible. The car can manage speed and steering together, for example holding a gap to the vehicle ahead while keeping the car centred in its lane, but the driver must keep eyes on the road and hands near the wheel, and must be ready to take over without warning. The car does not "drive itself" at Level 2, and every carmaker's brochure says so in the footnotes. Honda's wording is typical: Honda SENSING "cannot substitute human acumen and vigilance while driving".

The functions that make up a Level 2 package in India today are: adaptive cruise control (ACC), which holds a set speed and a set gap; lane keeping assist (LKA) or lane centring, which adds small steering inputs to stay in lane; lane departure warning and prevention; autonomous emergency braking (AEB) or collision mitigation, which brakes if a collision with a vehicle or pedestrian is imminent and you have not reacted; and high-beam assist. Some add a lead-car departure alert, which beeps when the car ahead moves off at a signal.

Three cars, three sensor philosophies

Toyota Glanza: camera-led, at the lowest price. Toyota's press release for the new Glanza lists adaptive cruise control, lane keeping assist, lane departure warning, lane departure prevention, autonomous emergency braking and high-beam assist, alongside six airbags, a 360-degree camera and TPMS. The hatchback starts at ₹6.99 lakh ex-showroom, with the ADAS package on higher grades. This is the Baleno's sibling, so expect the same supplier hardware as the Maruti, built around a windscreen-mounted camera with a compact front sensor.

Honda Elevate: single wide-angle camera. Honda SENSING on the new Elevate (₹11.80 lakh to ₹18.40 lakh ex-showroom Delhi) uses, in Honda's words, "a high-performance front camera with wide-angle, far-reaching detection capabilities". It delivers Collision Mitigation Braking, adaptive cruise, Road Departure Mitigation, Lane Keeping Assist, Lead Car Departure Notification and Auto High-Beam. The CVT variants add Low Speed Follow, which lets the ACC work in stop-and-go traffic down to a standstill. A single-camera system is cheaper and simpler to package, and Honda has used this approach globally for years.

Hyundai Bayon: camera plus three radars. Hyundai's Level 2 Pro package on the Bayon (₹9.99 lakh to ₹18 lakh ex-showroom) is the most hardware-rich of the three: 23 functions using a front camera, three radars and 12 parking sensors. The extra radars enable functions a camera cannot do alone: Highway Driving Assist, navigation-based cruise control that slows for curves and speed-limit zones, a blind-spot view monitor that puts a camera feed in the cluster when you indicate, and rear cross-traffic alert.

Camera versus radar, and why the difference shows on Indian roads

Bosch, which supplies much of this hardware globally, explains the division of labour on its sensor-fusion page: the radar "is particularly good at measuring longitudinal distances and speeds irrespective of the weather conditions", while the camera "features a very high level of precision when it comes to lateral measurements". Translated: radar knows how far away the car in front is and how fast it is closing, in rain or dust; the camera knows where the lane lines are and what the object is (car, bike, pedestrian, cow). Fusing the two "greatly reduces erroneous warnings".

That last phrase is the Indian problem in one sentence. Bosch Mobility's CTO Mathias Pillin told ET Auto last year that a colleague "was constantly annoyed by unnecessary alerts from a western ADAS system in Bengaluru", and that "a key challenge here is the lack of lane markings, which many western systems rely on". Bosch's response is a cost-optimised single-camera package tuned for Indian road behaviour, with lane departure warning, AEB and ACC as its core.

What this means for you, function by function:

• ACC works well on expressways and the ORR. In mixed city traffic it brakes for two-wheelers that cut in, sometimes harder than you would. Set a longer gap and it is usable; set the shortest gap and it will nag.
• Lane keeping needs lane lines. On the Hyderabad–Vijayawada highway it is excellent. On a state highway with faded or missing markings it switches itself off, and the cluster will tell you so. This is normal, not a fault.
• AEB is the one that earns its keep. Bosch's data on sensor fusion shows the camera-plus-radar combination is what allows reliable pedestrian protection. Expect the occasional false warning from a parked car on a curve or a cow on the verge; expect it to save you from a rear-ender at a signal at least once in the car's life.
• High-beam assist is a mixed blessing on roads where oncoming trucks run no lights at all; some owners switch it off.

What to check before you pay for it

First, which variant. In all three cars the Level 2 package is on the upper trims, so the headline ₹6.99 lakh Glanza price buys the body and the airbags, not the ADAS. Second, whether the automatic gets more than the manual. Honda's Low Speed Follow is CVT-only, and the same split appears in other brands because a manual cannot creep in traffic on its own. Third, the radar count. A single-camera system (Glanza, Elevate) gives you the core safety functions; a radar-equipped system (Bayon) adds blind-spot and cross-traffic functions that are genuinely useful in Indian parking and on multi-lane roads. Fourth, ask the dealer to show you how to adjust the sensitivity and how to turn individual functions off. A system you cannot tune is a system you will switch off entirely, which wastes the money.

The Auto Grid angle

Where the sensors sit matters to us. The front radar on a Bayon-class car lives behind a painted panel in the bumper or behind the badge; the camera sits behind the top of the windscreen. We see the consequences in the bay: a bumper that has been resprayed after a scrape with too many coats, or with a heavy metallic flake, can attenuate the radar signal enough to throw a fault, and a cracked windscreen replaced by a non-OEM glass can shift the camera's calibration. Quality paint protection film is radar-transparent and does not interfere with the camera, which is why we fit it over the sensor zones without hesitation. The bigger point is that a car wearing film from week one is a car that never needs a bumper respray, so the radar calibration set at the factory stays set. For a car whose safety case depends on a sensor behind the paint, keeping the original paint is part of keeping the system honest.

Where this goes next

Maruti's facelifted Baleno, the Glanza's twin, now carries ADAS too, and Bosch's India-specific single-camera system is designed to drive the cost lower still. Bharat NCAP's star ratings today are driven by crash tests; when it starts to award points for AEB, as Euro NCAP does, expect Level 2 to become standard rather than optional across the ₹10–20 lakh band. The hardware is already cheap enough. What is still being tuned is the software's understanding of an Indian road.
