A Manic Mighty Mite from AMG


There’s an much more manic model of the Mercedes-AMG GLA coming: The Mercedes-AMG GLA 45, with 382 hp and 354 lb-ft of torque, will be part of the GLA 35 in U.S. Mercedes dealerships earlier than the tip of the 12 months. Pricing has 12 months to be introduced, however do not count on a lot change from $55,000.

And what does paying one thing like $8,000 greater than you’d for the GLA 35 purchase you?

It buys you the world’s strongest 2.0-liter manufacturing engine, for a begin. Codenamed M139, and each hand-built by an AMG technician in Affalterbach, it makes its 382 hp at 6,500 rpm, with the 354 lb-ft of torque accessible from 4,750 to five,000 rpm, sufficient to clip 0.7 second from the GLA 35’s 5.0-second zero-to-60 acceleration time.

Though similar when it comes to bore and stroke to the turbocharged 4 that powers the GLA 35 and the common GLA fashions, the M139 is a considerably completely different engine.

In contrast with the GLA 35 and other GLA models, the M139 has been turned 180 levels within the engine compartment so the consumption is on the entrance of the automotive and the turbocharger and exhaust are close to the firewall. AMG says this configuration permits probably the most aerodynamically advantageous front-end design and extra direct air and gasoline flows on each the consumption and exhaust aspect. Different adjustments embody a turbocharger that not solely includes a twin-scroll impellor to assist with low-end torque and curler bearings to enhance response but in addition has a turbine housing with two parallel stream passages. Divided ducts within the exhaust manifold feed the exhaust stream to the turbine individually to forestall particular person cylinders from influencing one another negatively throughout load cycles, and to enhance the gasoline cycle. The outcome, in accordance with AMG, is larger torque at decrease engine speeds and intensely good responsiveness.

Element engineering adjustments embody a high-pressure, two-stage fuel-injection system and a cooling system that allows the cylinder head and crankcase to be cooled to completely different temperature ranges—the cooler cylinder head permitting most output by aggressive ignition timing, the hotter crankcase serving to scale back friction within the bores and crankshaft bearing.

The M139 drives by AMG’s Speedshift eight-speed dual-clutch transmission and the top-end AMG Efficiency 4Matic+ all-wheel-drive system, which includes a rear differential with two electronically managed multidisc clutches that, relying on the drive mode chosen, enable the drive torque to be individually distributed to both rear wheel. Six drive modes can be found: Slippery, Consolation, Sport, Sport+, Particular person, and Race (which comes with the elective AMG Dynamic Plus bundle), every altering the traits of the powertrain, suspension, and exhaust. In Race mode drivers also can set the steadiness and traction management techniques to Grasp mode, which sharpens the steering and permits energy oversteer.

The usual brake setup is identical as within the GLA 35—13.8-inch rotors and four-piston calipers up entrance and 13.0-inch rotors and single-piston calipers on the rear. Order the AMG Dynamic Plus bundle, nonetheless, and the entrance brakes get swapped for 14.2-inch rotors and six-piston mounted calipers. And the brake calipers are painted pink reasonably than silver.

When it comes to exterior styling, the GLA 45 has the identical toothy grimace because the GLA 35 up entrance however will get a indifferent rally-style wing over the rear window and 4 3.2-inch exhaust shops on both aspect of a extra aggressively styled rear “diffuser.” As with the unique GLA 45, it has little aero flics on the entrance corners, however they’re much less aggressively rendered.

We liked the previous-generation GLA 45, describing it as a riot on wheels that begged to be pushed to wring the engine for all its value: “Enjoyable! Enjoyable! Enjoyable!” senior options editor Jonny Lieberman raved after sampling it. “That is the Subaru STI wagon alternative we have all been ready for!” However our expertise with the GLA 35 has us questioning whether or not we’ll be as enamored of this second-generation GLA 45. It isn’t simply that we’re fearful the brand new 45 could have the identical poor experience and numb chassis; we suspect that, as with the 2021 GLA 35, the three.6-inch improve in total peak over the earlier mannequin will make the redesigned GLA 45 really feel like simply one other tall, lumbering, overpowered SUV reasonably than a road-legal rally racer you may hurl down a gravel street with an ear-to-ear grin.
