BMW 3 Series Expert Review

Design-wise, the 2025 M340i builds on the 2024 facelift, retaining the aggressive bumper, LED headlamps with twin-inverted L-shaped DRLs, and honeycomb grille elements. New Arctic Race Blue paint and blacked-out alloy wheels with red brake calipers are the only visual updates, helping it stand out while keeping the familiar sporty stance intact.

Cabin changes are limited to a new flat-bottomed steering wheel with a red 12 o’clock marker and revised central air vents that feel a bit flimsy. The touchscreen now runs updated software but still feels cluttered. Though climate buttons are gone, temperature controls are easily accessible on-screen.
Sporty front seats with adjustable bolstering and Alcantara trim give the cabin a proper performance feel. Rear seat space is on par with the standard 3 Series but trails the long-wheelbase version. The 480-litre boot, along with a space-saver spare tyre, adds practicality.
 

Its 3.0-litre straight-six turbo petrol (B58) continues with 374hp and 500Nm, paired to a quick and intuitive 8-speed torque converter automatic. In Sport mode, the exhaust note (partially synthesised) adds drama, with real-world figures showing 0–100kph in just 4.39 seconds. The transmission is smooth, responsive, and complements spirited driving perfectly.

Fuel economy, aided by a 48V mild-hybrid system, is claimed at 13.02kpl. However, expect single-digit figures in the city, with double digits achievable only on relaxed highway runs.

The new Adaptive M Suspension is a game-changer. In Comfort mode, the ride is more pliant than before, making it better for daily commutes. In Sport mode, it firms up to deliver sharp handling and precise steering. The switch to 19-inch wheels enhances looks but increases the risk of sidewall damage over rough roads.

The M340i packs in plenty: xDrive AWD, launch control, drive modes, paddle shifters, sport exhaust, HUD, 360-degree camera, ambient lighting, wireless charging, and a 16-speaker Harman Kardon audio system. However, it still lacks ventilated seats and ADAS features—noticeable omissions in this price bracket.

Priced at Rs 74.90 lakh (ex-showroom), the M340i is about Rs 6 lakh more than the previous version. However, the improved comfort and retained driving thrills make it worth the premium. With explosive performance, solid equipment, and added practicality, this updated M340i hits the sweet spot for those seeking an everyday performance sedan under Rs 1 crore.
