The GLC-Class is one of Mercedes’ best-selling luxury SUV crossovers in recent times. To spice things up, Mercedes plays around with the AMG nametag to integrate luxury with performance and create one of the hottest crossover prospects, the 2021 AMG GLC 63 SUV. A Biturbo V-8 under the hood should give you further incentive to consider it as a serious performance junkie.

High-performance SUVs have been the rage for quite a time now. This industry gets more cutthroat competition as new performance SUVs from reputed automobile marquees roll out every year. The 2021 Mercedes-AMG GLC 63 faces some serious rivalry from the likes of performance stalwarts like BMW X3 M, Porsche Macan Turbo, and Alfa Romeo Stelvio Quadrifoglio. Can the 2021 Mercedes-AMG GLC 63 SUV excel where it counts the most with its stellar performance?

What’s the Engine under the 2021 Mercedes-AMG GLC 63 SUV’s Hood?

Mercedes powers its 2021 AMG GLC 63 SUV with its handcrafted 4.0-liter twin-turbo V-8 engine. This Biturbo V-8 punches the heavy SUV above its weight with its robust power output of 469 hp and 479 lb-ft of torque. Mercedes mates this engine to a 9-speed automatic transmission with overdrive for the most efficient power transmission. All-wheel-drive is standard on the AMG GLC 63 which gives the SUV added stability and grip on slippery and icy roads.

The AMG Biturbo V8’s specialty is to give you greater lateral acceleration and motorsport-level performance figures, all while cruising with the sweet-sounding roar of the V-8. The AMG SPEEDSHIFT 9-speed automatic transmission is also the best in its business, transmitting sufficient power to all 4 wheels to give you a smooth transition while speeding up. Mercedes AMG 4MATIC+ all-wheel-drivetrain is another industry-leading technology that excels on any harsh terrain with its efficient power and torque distribution.

The Mercedes-AMG GLC 63 is right on par with its fierce rivals in terms of horsepower. Although it may not beat the Stelvio Quadrifoglio's astounding 505 horses, it possesses the highest torque in its segment with a leading 479 twisties.It also has the biggest engine and only V8 in its segment. The BMW's in-line six is still a surprise contender though. 

How fast is the 2021 Mercedes-AMG GLC 63 SUV from 0-60 MPH?

The 2021 Mercedes-AMG GLC 63 is a force to be reckoned with its monstrous Biturbo V-8 speeding up the SUV beyond the 60 mph mark in just 3.8 seconds. This 0-60 time is quite impressive for a performance SUV and puts the AMG GLC 63 on par with some of the best performance sedans out there.

The smooth-shifting transmission is a perfect fit for the shaky but thunderous V-8. The class-leading torque figure also lends it tremendous acceleration while speeding up which is pretty much what you would expect by Mercedes-AMG’s standards.

The Alfa Romeo Stelvio Quadrifoglio is the leader of its pack with its breezy 0-60 mph timing of 3.6 seconds, just two tenths of a second faster than its nearest competitor, our very own AMG GLC 63. However, the BMW X3 M outclasses the Stelvio Quadrifoglio over the longer quarter-mile stretch, with its timing of 11.6 seconds. 

How good are the Brakes of the 2021 Mercedes-AMG GLC 63 SUV?

The AMG nametag brings more than just performance to the table. Other factors also feel the influence of this illustrious partnership including braking. The AMG GLC 63 SUV features ventilated disc brakes on both the front and rear ends to stop the momentum of the heavy SUV within seconds.

The active brake assist also comes in handy during critical situations, applying the brakes by itself to reduce the impact of a collision and safeguard you from further harm.

Automakers haven’t revealed much about the braking data about their high-performance SUVs except BMW. The BMW’s 60-0 braking distance of 104 feet is sensational for a vehicle of its size.We expect altogether cars to be in this range as well, but we cannot comment on them because data is not available as of yet.

How does the 2021 Mercedes-AMG GLC 63 SUV handle around the corners?

The AMG-prefix with the GLC-class promises exactly what you hoped for, killer performance with sleek handling that would make it a treat to drive on the Autobahn. But its dedication towards power makes the ride too stiff at times. Stepping freely over road imperfections may not inspire much confidence from the driver. Still, the SUV is a delight to drive on most highways thanks to its free-spirited engine and a quiet cabin.

The handling is buttery smooth and the SUV scales corners much better than your regular everyday drive. Merc also grants you the privilege of 5 driving modes to choose from, including Sports and Comfort modes to customize your ride quality as per the situation. Want to explore the wilderness? The AMG 4MATIC+ system and the AMG Air Suspension system say yes, as the SUV glides over any coarse terrain ranging from gravel, mud, sand, and snow. After all, that’s why you are shelling out those thousands of dollars for.

What MPG figures can you expect from the 2021 Mercedes-AMG GLC 63 SUV?

The 2021 Mercedes-AMG GLC 63 can spin around for a below-average MPG of 16 in the city. The highway MPG of 22 sounds like a much-needed relief but is still a below-average figure. This equates to a city range of 278 miles and highway range of 383 miles which isn’t very much on the wavelength of a family car. The AMG GLC 63 has a combined MPG of 18 which is pretty much on par with most high-performance SUVs out on the market.If you're after more fuel-efficient options then must release itself offers the GLC 43 which is a better compromise between performance and efficiency.

You can’t blame Mercedes for the subpar fuel economy, as the star-studded performance figures do rob away some of the valuable MPG figures. The AMG GLC 63 has a humongous tank capacity of 17.4 gallons. Still, the fuel-hungry SUV will leave you wanting for more fuel stops, which serves as a wet blanket for those otherwise joyful outings with your SUV.

It is the same sad story in the fuel economy department for all the high-performance SUVs. The Alfa Romeo Stelvio Quadrifoglio is the most economical SUV of the lot with the Porsche Macan Turbo just following behind.This, combined with its larger fuel tank gives the Macan much higher range. 

Should you buy the 2021 Mercedes-AMG GLC 63 SUV?

The thrilling power and the thunderous roar of the Biturbo V8 should be more than enough justification for the lavish $74,000 price tag of the 2021 Mercedes-AMG GLC 63 SUV.If you're after a more cost-effective option as the lesser AMG, the GLC 43 or the GLC Class. If you're after an even more cost-effective option you can pick up a used one for lesser. The AMG GLC 63 dominates its cutthroat segment with much courtesy to its awe-inspiring spec sheet. Be it Formula1 or your regular utilitarian SUV, Mercedes-AMG creates performance beasts out of their cars that highlight their prowess on the race field whenever it matters the most. The 2021 Mercedes-AMG GLC 63 is another marvel from the Stuttgart marquee that offers no compromise on performance and opulence.
