B&B Automobiletechnik, a German tuning specialist, has introduced a comprehensive performance upgrade package for the Mercedes-Benz CLA 45 AMG.

Overview of B&B's CLA 45 AMG Tuning Programme
Details of the Three-Stage Tuning Packages
The B&B tuning programme is structured in three distinct stages, each offering progressively higher performance. The entry-level Stage 1 package centres on electronic optimisation, with an ECU remap increasing the output to 400hp and 510Nm of torque. This initial upgrade is priced at €1,298. Stage 2, costing €3,950, builds upon this with the addition of a free-flow downpipe and a new air intake, further increasing power to 425hp and 540Nm. For those seeking the ultimate in performance, Stage 3 incorporates a larger turbocharger alongside the previous modifications. At €6,950, this final stage delivers 450hp and 680Nm, with B&B claiming the car can accelerate from 0 to 100km/h in just 3.6 seconds and reach a top speed of 296km/h.

| 1 | ECU remap | 400hp | 510Nm | 1,298 |

Chassis and Hardware Upgrades
In addition to engine tuning, B&B offers a suite of hardware upgrades designed to complement the increased power. Customers can opt for a high-efficiency oil cooling system to support engine durability under high loads. Suspension options include coilover systems and sport springs, which lower the ride height by up to 30mm at the front and 25mm at the rear, improving handling and road presence. A high-performance braking system is available for enhanced stopping power, while 20-inch alloy wheels provide both visual impact and improved grip.

Performance and Market Position
With the Stage 3 package, the CLA 45 AMG by B&B stands out as one of the most powerful four-cylinder saloons available through aftermarket tuning. The claimed figures put it ahead of many rivals in terms of straight-line acceleration and top speed. These upgrades make the CLA 45 AMG a compelling choice for enthusiasts who prioritise performance and individuality over factory-backed exclusivity. For those who prefer a more limited edition, the factory-offered Edition 1 remains an option, but B&B’s staged upgrades provide a clear path to maximising the potential of the M133 engine platform.
Summary
The Mercedes-Benz CLA 45 AMG by B&B Automobiletechnik demonstrates the potential of aftermarket tuning for compact performance saloons. With staged engine upgrades, supporting chassis enhancements, and a focus on both power and durability, this package offers a comprehensive solution for owners seeking to elevate their CLA 45 AMG beyond its already impressive factory specification.
