2016 Mercedes-AMG A45 Regains Title Of Most Powerful And Fastest Hot Hatch From RS3
Thanks to a newly configured valve assembly and by reconfiguring timing and turbocharging to optimize the combustion process, AMG engineers managed to harness another 21-horses from the 2.0-liter force-fed four, pushing output from 355hp (361PS) and 450Nm (332 lb-ft) to 376hp (381PS) and 475Nm (350 lb-ft) respectively.
The new A45 AMG completes the benchmark sprint to 100km/h (62mph) in 4.2 seconds, which is 0.1 second faster than the RS3 Sportback, and 0.4 seconds faster than the outgoing A45 AMG, yet fuel consumption has been kept at the previous levels at 6.9l/100km (34.0 mpg US / 40.9mpg UK that corresponds to 162 g/km CO2. Top speed is once again limited to 250km/h (155mph).
Mercedes also revised the 7-speed dual-clutch transmission with shorter ratios in 3rd to 7th and new software, while adding a new AMG Dynamic Plus package that includes a newly developed, mechanical front axle locking differential to "significantly" improve traction.
Like its European counterpart, the 2.0-liter turbocharged four-cylinder in the diminutive AMGs receives upgrades to produce 375 horsepower and 350 pound-feet of torque (the 381 hp rating over there is in metric ponies). That's an impressive 20-horsepower and 18 lb-ft bump over the current version of the mill. Beyond just the boost in output, quicker acceleration comes from revised, more aggressive ratios in third through seventh gears.
The latest AMGs make great use of their upgrades, too. The 2016 GLA45 now clocks the run to 60 miles per hour in 4.3 seconds, a staggering half-second quicker than the 2015 model. The CLA45 slices 0.3 seconds off its time to make the sprint in 4.1 seconds, which gives the sedan the same acceleration as a SL63 AMG.
Yah sadly no one buys them in the US.
Here's the Infiniti competition the Q3.
