2022 Mercedes-Benz GLE-Class SUV Performance

GLE是提供三个引擎的选择,paired with a nine-speed automatic transmission. The entry-level GLE 350's turbocharged 2.0L four-cylinder engine develops 255 horsepower and can complete the 0-60-mph sprint in seven seconds in RWD guise and 7.1 seconds with AWD. The GLE 450 4Matic's 3.0-liter inline-six with EQ Boost mild-hybrid assistance offers 362 hp and completes the 0-60 sprint in 5.5 seconds. Both the GLE 350 and 450 models are limited to 130 mph. The GLE 580's twin-turbo 4.0-liter V8 with EQ Boost develops 483 hp and 516 lb-ft of torque, good enough for a 4.9-second sprint time and a higher top speed of 155 mph. The 3.0-liter turbocharged engines of the GLE's key competitors both develop less power, but it matters little as the lighter BMW X5 hits 60 mph in 5.3 seconds and the more powerful version drops into the low fours. The heavier Audi Q7 is slowest at 5.7 seconds. Towing capacities for the GLE vary from 5,950 pounds for the RWD GLE 350 up to 7,700 lbs for the 450 4Matic. The top-tier GLE 580 has not been rated.

The base 2.0-liter gas engine in the GLE 350 does without hybrid assistance and produces 255 hp and 273 lb-ft of torque, which is transmitted to the road via a nine-speed torque-converter automatic transmission common to all GLE models. This model is available in RWD or 4Matic AWD. Performance is adequate and the engine is acceptably refined if not extended. The GLE 450 is a significant step up with a 3.0-liter gas engine supplemented by a 21-hp/184-lb-ft EQ Boost hybrid-assistance system. Its 362 hp and 369 lb-ft are delivered in a creamy smooth fashion and it's much more refined than the four-pot.

The most expensive GLE 580 is the only non-AMG GLE with a V8 - a 4.0-liter with 483 hp and 516 lb-ft, also with EQ Boost. It offers a stirring soundtrack and performance, but the GLE 450 is the performance/economy king in the range and arguably the best combination of all the models' attributes. The EQ Boost system ensures instant response without lag and returns gas mileage that narrowly beats even the GLE 350. We would look no further than the GLE 450 with its supremely smooth and punchy inline-six.

One would expect the entry-level 2.0-liter to be the most economical GLE in the range, but this is not the case, because it is also the only GLE not to benefit from the fuel-saving EQ Boost mild-hybrid tech. City/highway/combined fuel economy is a respectable 19/27/22 mpg for the RWD and 19/26/22 mpg for the 4Matic GLE 350 models, but the GLE 450 edges them out with figures of 21/25/23 mpg, despite far superior performance and better refinement. It's an impressive performance/economy blend and even the lighter X5 xDrive40i can only just match it. The Q7 puts in a poor showing with 18/23/20 mpg. Predictably, the GLE 580 fares considerably worse than its siblings, with 17/22/19 mpg. A generous 22.5-gallon gas tank will get a GLE 450 as far as 585 miles on the highway before it runs dry and over 515 miles on the combined cycle.
