Highlights

The BMW M135i is already a standout in the premium hot hatch category, but the tuning wizards at AC Schnitzer have taken this already impressive machine to another level. AC Schnitzer, renowned for its precision tuning and enhancements, has imbued the M135i with more power, sharper handling, and an aggressive aesthetic overhaul.

Driving

The AC Schnitzer-tuned BMW M135i delivers a thrilling driving experience

The AC Schnitzer-tuned BMW M135i delivers a thrilling driving experience that surpasses its standard counterpart. The 2.0-liter turbocharged inline-four engine has been upgraded to produce an exhilarating 400 horsepower, a significant increase from the stock 302 horsepower. This power boost is accompanied by a reworked suspension system that includes sport springs, lowering the ride height by approximately 25 mm. This not only enhances the car’s aggressive stance but also improves its handling dynamics, making it more responsive and agile.

The enhanced engine performance is immediately noticeable, with a 0-60 mph time of just 4.3 seconds. The acceleration is smooth and relentless, and the car feels planted and stable even at high speeds. The steering is precise, offering excellent feedback, and the re-tuned exhaust system provides a satisfying growl that underscores the car’s sporty nature.

Interior

Inside, the AC Schnitzer BMW M135i retains much of the luxury and functionality of the standard model

Inside, the AC Schnitzer BMW M135i retains much of the luxury and functionality of the standard model, but with a few bespoke touches that enhance its sporty credentials. The interior is dominated by high-quality materials, including Alcantara and leather, which give the cabin a premium feel. AC Schnitzer has added their signature elements such as aluminum pedals, bespoke floor mats, and an optional sports steering wheel with a flat bottom and additional grips for a racier feel.

The front seats are comfortable and supportive, perfect for both spirited driving and long-distance cruising. However, the rear seats remain somewhat cramped, typical of this segment. The infotainment system is intuitive and packed with features, including a high-resolution display, navigation, and connectivity options.

Practicality

The practicality of the AC Schnitzer-tuned M135i is similar to that of the standard model

The practicality of the AC Schnitzer-tuned M135i is similar to that of the standard model. It offers a decent amount of space for a hot hatch, with 380 liters of boot space, which can be expanded by folding the rear seats. This is sufficient for most daily needs and weekend getaways.

In terms of everyday usability, the M135i strikes a good balance between performance and practicality. It’s compact enough for city driving and parking, yet spacious enough to accommodate a small family or a couple with active lifestyles. However, the lowered ride height may pose a challenge when navigating speed bumps or rougher terrain.

Costs

When it comes to costs, the AC Schnitzer M135i commands a premium over the standard model

When it comes to costs, the AC Schnitzer M135i commands a premium over the standard model. The cost of the tuning package and modifications can add a significant amount to the base price of the car. Additionally, maintenance and running costs are likely to be higher due to the specialized parts and performance enhancements.

Fuel efficiency is also impacted, with the enhanced engine consuming more fuel, especially when driven aggressively. However, for enthusiasts who value performance and exclusivity, the added expense is justified by the substantial improvements in power, handling, and overall driving experience.
