Mercedes-AMG’s CLA45 compact sedan might work the door at Affalterbach’s internal-combustion madhouse. But with a transverse inline-four engine producing a bonkers one-hundred and eighty-eight horsepower per liter, it makes for one helluva greeter. A host of recent updates have made the 2017 Mercedes-AMG CLA45 4Matic already a serious performer in order to first showed for 2014–even stouter for 2017, albeit with little addressing of its underlying issues.
With its scrappy frame of mind and raucous four-cylinder blat, the all-wheel-drive CLA45–and their GLA45 hatchback crossover twin–has always traded some decorative for boost pressure. A twin-scroll turbocharger still pumping systems a hefty 26. 1 psi into AMG’s hand-assembled 2. 0-liter M133 work. But the addition of a new exhaust camshaft and a retuned computer for 2016 have upped its output by 20 horsepower and 18 lb-ft of torque for heady totals of 375 and 350. Amplified by our example’s $650 AMG Overall performance exhaust system, the CLA45 buzzes through its add some opuch range like a chainsaw–at up to 88 decibels under full duress–and emits a sharp brrapp on upshifts at anything more than fifty percent throttle.
2017 Mercedes-AMG CLA45 4Matic Exterior
A snappy, seven-speed dual-clutch programmed wirings the engine’s output with deft control, readily offering up rev-matched downshifts in its more aggressive options and offering precise kinesis via shift paddles on the CLA’s steering wheel. The AMG-tuned transmission still can be a lttle bit clunky at slower speeds–witness our test car’s rather pokey 5. 3-second pull from 5 to 60 mph–but the quickness on the move helps counter the separation from the big turbo. Although the 45 generally operates as a front-driver, its standard 4Matic all-wheel-drive system can route up to 50 percent of the powertrain’s torque to the rear axle when needed.
With its peak rpm plateauing from 2250 to 5000 rpm and all 375 horses in presence at 6000 revs, the 2017 Mercedes-AMG CLA45 4Matic hits quick and hard as it boosts to an electronically governed 155-mph top speed (or 167 mph if prepared like our test car). AMG’s launch-control system can be engaged in the sportier driving modes by standing on the foot brake pedal, toggling the paddle shifters, and flooring the throttle, all of which holds the revs at about 3000 rpm as it produces the sound of firecrackers exploding from the 45’s exhaust water lines. Let go of the brake and the 3563-pound sedan blasts to sixty mph in 3. 8 seconds and covers the quarter-mile in 12. 3 at 113 mph–a solid 0. 4 and zero. 5 second (and 3 mph) quicker than before and not far behind the last 503-hp Mercedes-AMG C63 S sedan we tested.
2017 Mercedes-AMG CLA45 4Matic Specs
Part of the $2800 AMG Active Plus package, the pack also includes the higher top-speed rating, a sport-tuned suspension with two-way driver-adjustable dampers, and a maximum-attack Race mode added to the car’s standard Comfort and ease, Sport, and Sport+ settings. Our example rode on $850 19-inch aluminum rims in place of the stock 18s and was shod with 235/35ZR-19 Dunlop SP Sport Maxx RT performance tires.
Compared with the 2014 model we tested on similar Continental ContiSportContact 5P rubber, the new setup glued the “2017 Mercedes-AMG CLA45 4Matic” to the skidpad with a complete 1. 00 g of grip (up from 0. 94 g), topping any AMG-fettled C-class and matching the 10Best Cars-winning BMW M2. The sticky Dunlops also helped the 13. 8-inch entrance and 13. 0-inch back brakes bring this AMG to a halt from 70 mph in an impressive 150 feet with zero fade.
AMG’s revisions allow it to change way more assertively and with smoother flow at extralegal speeds. Your body stays almost tabletop flat in bends, and the electrically made it simpler for power steering twirls with precision and a right amount of feel. Our car also featured beautiful Recaro performance seats ($2250) with red piping that bearhugged front-seat occupants with supportive side bolsters.
2017 Mercedes-AMG CLA45 4Matic Interior
The CLA’s swoopy, compact proportions don’t lend it Mercedes-Benz’s most handsome four-door coupe design, but a moderate facelift for 2017 does indeed align it better with newer products from the carmaker. Subtle tweaks to the front and rear bumpers including tacky carbon fiber aero canards let it slip through the air more efficient and standard LED headlights. Along with $300 red brake pedal calipers, our test car’s Designo Polar Silver Grande matte paint boosted the curbside occurrence and added $2500 to the price, but the rip-snorting wear out note remains this AMG’s greatest tell.
Minor becomes the interior include revised trim finishes and an updated 8. 0-inch central display handled via a console-mounted rotary knob, but a quick scan still reveals some cost trimming on materials. This car’s rear seat remains especially tight with sedan sloping roof line severely limiting headroom. And many basic conveniences cost extra, such as heated seats, distance entry and push-button start, and Apple CarPlay and Android Auto connectivity.
The 2017 Mercedes-AMG CLA45 4Matic standard black m? cor is prominently spiced with red accents, including the seatbelts (black belts are a no-cost option), contrast stitching, the bezels for the HVAC vents, and red-and-silver AMG Design graphics on the dashboard. The example went a step further with the $1650 AMG Red Cut Exclusive package, which adds dark leather upholstery with more contrast stitching, ambient in house lighting, and top-stitched MB-Tex trim on the top splash and door panels. Nevertheless the overall effect remains those of a juvenile delinquent outfitted for a court day.
2017 Mercedes-AMG CLA45 4Matic Prices
Such customization features the 2017 Mercedes-AMG CLA45 4Matic greatest condition: Its not-insignificant $50, 945 starting price is but $2050 below that of Mercedes-AMG’s classier and more comfortable C43 sedan. Element in all of the aforementioned extras and $6650 worth of more infotainment, driver-assistance, and convenience amenities, and our $69, 095 test car cost practically $3K more than a big-dog C63 sedan with a twin-turbo AMG V-8 producing 469 horsepower. Even in the AMG asylum, where Formulation 1-engined road cars now roam the halls, that is crazy.
