With its raucous turbo four-cylinder and fiery efficiency, the compact CLA45 began off because the entry-level punk of Mercedes-AMG’s sedan vary when it debuted for 2014. However a lot has modified because it enters its sophomore technology on Benz’s newest CLA-class platform, together with the introduction of less-extreme A35 and CLA35 fashions on the backside of AMG’s lineup. For the redesigned 2020 CLA45—and its 2021 GLA45 crossover sibling—evolution has allowed it to lastly mature out of its adolescent hot-rod part with out dropping its sports-car-like skills.
Eager eyes will discover that an S, which denotes the brand new 416-hp S mannequin, just isn’t included on our check automotive’s trunklid badge. Whereas the S is offered in different markets, patrons in the USA solely get the usual tune for the hand-assembled M133 2.0-liter inline-four, which nonetheless advantages from a brand new twin-scroll turbocharger delivering extra enhance (30.1 psi versus the earlier 26.1), revised internals, and a brand new port and direct fuel-injection system. Peak horsepower is now 382 at 6500 rpm, up from the earlier CLA45’s 375 at 6000 rpm. Torque creeps up from 350 pound-feet at 2250 rpm to 354 at 4750 revs. The usual dual-clutch computerized transmission now has eight speeds as a substitute of seven, and the up to date 4Matic+ all-wheel-drive system beneficial properties a torque-vectoring rear differential to assist the automotive rotate round corners extra simply.
A brand new front-axle disconnect permits for tail-out antics on the racetrack, supplied you go for our check automotive’s $4300 AMG Dynamic Plus package deal. Together with redundant steering-wheel-mounted controls for the drivetrain, chassis, stability management, and the overarching AMG Dynamics automobile administration system, this complete bundle provides Race and Drift modes to the usual Consolation, Sport, Sport+, and Particular person setups. Dynamic Plus additionally brings a sportier suspension setup with adaptive dampers, bigger brake rotors with red-painted calipers, a leather- and suede-wrapped AMG steering wheel, a 167-mph top-speed governor (up from 155 mph), an lively efficiency exhaust and AMG’s Monitor Tempo data-logging system.
Our scales say that the second-gen CLA45 placed on 180 kilos, thanks largely to its added options and bigger dimensions; it is two inches wider than earlier than and an inch longer each general and in wheelbase. But, our 3743-pound check automotive posted roughly the identical efficiency outcomes of the final CLA45 we examined: a launch-control-enabled 3.7-second 60-mph time, 0.99-g grip on the skidpad, and a 154-foot cease from 70 mph. What’s extra, regardless of the load achieve, our noticed gasoline financial system jumped from 20 mpg to 24, and the return on our 75-mph freeway check improved from 31 mpg to 34—a strong 5 mpg higher than the CLA45’s EPA estimate. Apparently that additional gear makes a giant distinction.
Though the M133 4 has a comparatively high-rpm torque peak, AMG’s revisions make it impressively tractable and brief on lag. Aided by the brand new transmission, its 5-to-60-mph time (5.1 seconds) is 0.2 second faster than earlier than. There is a honest quantity of clutch slippage from the transmission when setting off, in addition to some clunky downshifts at low speeds round city. However the brand new dual-clutch field is in any other case ultrasharp and neatly programmed to downshift and maintain gears when it ought to. Launch the CLA45 down the quarter-mile in Race mode and speedy upshifts include agency kicks to your bottom. Simply do not count on to beat an Audi RS3 within the different lane, because the CLA45’s 12.2-second move at 114 mph cannot match the Audi’s high-11-second run.
Our check automotive’s lively exhaust produced loads of snorts and pops when pushed aggressively, pinging our sound meter with 90 decibels at full throttle in Race mode, up from the earlier mannequin’s 88 decibels. Depart the brand new automotive’s system in the usual mode, and it calls noticeably much less consideration to itself. But it surely’s far more enjoyable to hit the loud button and take within the candy growl from the brand new AMG 2.0-liter. In comparison with the flat, buzzy engine observe of most four-bangers, together with the earlier CLA45’s, there is a pleasing richness to the up to date engine’s tone that had us continuously looking for its 7000-rpm redline.
The CLA45’s maturation is most important in its chassis, which enjoys elevated suspension journey and higher isolation from the offended four-cylinder beneath the hood. Driving on short-sidewall 255/35R-19 Michelin Pilot Sport 4S summer season tires (18-inchers are a no-cost choice), AMG’s compact sedan nonetheless rides poorly on tough roads when its dampers are of their stiffer settings. However there’s now sufficient flexibility and trip compliance to traverse smoother pavement with out smacking the bump stops. The brand new CLA45 will calm down just a little in order for you it to, one thing its predecessor merely by no means did. Physique management by corners stays glorious, and the direct and firmly weighted steering does convey some really feel as lateral forces construct. A great deal of grip from the sticky Michelins ends in little of the cussed understeer in tight corners that we typically count on from transverse-engine sports activities sedans.
Sit down within the CLA45’s agency, closely bolstered AMG Efficiency thrones ($2690) and the brand new CLA’s additional width is as obvious as it’s welcome. Together with a extra accommodating again seat (though one that’s nonetheless tight on headroom for taller riders), the general atmosphere feels rather more inviting. Now not does each inside floor vibrate to the thrum of the engine, making it simpler to get pleasure from a cabin match for an entry-luxury automotive. You’ll be able to nonetheless get your fill of purple accents and distinction stitching, and purple seatbelts stay normal. (Black belts are not any cost.) However our instance’s subdued grey-and-black upholstery and black wooden trim seemed restrained and complicated, complimenting the plentiful brightwork and vibrant 10.3-inch instrument and middle shows. Benz’s newest MBUX infotainment system, with its middle touchpad and tiny steering-wheel controllers, nonetheless requires extra involvement to function effectively than we would like. However ergonomics in the end aren’t this AMG’s weak level.
The CLA45’s biggest concern stays its pricing. The second-generation’s enhancements and options have elevated its entry level by $1700 over final yr, to $55,795. Nevertheless, all of our check automotive’s efficiency choices—together with the $1700 Driver Help package deal, $1150 embedded navigation system, and extra—inflated its window sticker to $73,850. At which level pace junkies shall be extra glad with AMG’s $69,095 C63 sedan and its 469-hp twin-turbo V-8. Stretch and you’ll land the 503-hp C63 S four-door for $76,695. However go simple on the CLA45’s upgrades and you will find that AMG’s punk is now a compelling small sports activities sedan, one which calls for far fewer tradeoffs for its youthful exuberance.
