Three flavors of fun for the German four-door coupe
Since 1984, B&B Automobiltechnik has been tuning and modifying Volkswagen automobiles. When 2005 rolled around, the tuner decided that it was time to expand their portfolio into other German marques, including Mercedes-Benz. The CLS 45 AMG is a German four-door coupe, just like the Passat CC that B&B Automobiltechnik has pumped up in the past, and their newest program is more of the same fun stuff.
Three stages of power tuning are available for the Mercedes-Benz CLA 45 AMG from B&B Automobiltechnik along with some curve-carving upgrades for the suspension and chassis.
The basic, Stage 1 program for the CLA 45 AMG’s 2.0-liter turbocharged inline-four encompasses a new ECU tune that alters the boost pressure, along with fuel and ignition mapping to increase output to 400 horsepower and 376 lb-ft. of torque for a cool 1,298 Euros.
In Stage 2, things get a little more exciting for the German four-door coupe. The ECU tune in Stage 1 is paired up with a new air intake system and a B&B downpipe for a total of 425 horsepower and 398 lb-ft. of torque for 3,950 Euros.
The mighty Stage 3 includes the aforementioned upgrades along with a new turbocharger that is the centerpiece of the upgrade. A full cold air intake and exhaust downpipe with custom-tuned ECU mapping results in a whopping 450 horsepower and 428 lb-ft. of torque for a total of 6,950 Euros. With the Stage 3 package, the Mercedes-Benz CLA 45 AMG can sprint to 62 mph in just 3.8 seconds and reach 124 mph in 14.3 seconds. The factory top speed limiter of 155 mph has also been removed, allowing the four-door coupe to reach 184 mph. The transmission shift protocols have also been altered to handle the increase in power and its band in each of the ECU tunes.
Customers also have the option to order the B&B oil-cooling system and exhaust downpipe setup. The oil cooler helps to reduce temperatures during high-performance driving for 1,495. The downpipe setup reduces backpressure and lowers temperatures for an extra 20 horsepower by itself.
B&B Automobiltechnik didn’t just focus on upping the power either. The Mercedes-Benz CLA 45 AMG also has some goodies to make carving up corners even more exciting. A B&B spring set reduces ride height by 30- and 25 mm at the front and rear, respectively or customers can opt for the in-house coilovers that allow for adjustable height, damping, and rebound. A larger six-piston high-performance braking system helps to bring the four-door coupe to a halt even quicker. To complete the setup, a new set of B&B five-spoke wheels measuring 8.5J x 20 with 235/30 ZR20 at the front and rear were installed.
All of the featured upgrades from B&B Automobiltechnik are currently available for the Mercedes-Benz CLA 45 AMG as an entire package or individual upgrades.
