The X4 has the lowest power and torque output, the slowest 0-60 mph and quarter-mile times, and the second-longest braking distance of the bunch. It is powered by a 3.0 liter turbocharged inline-six making 300 horsepower and 300 lb-ft of torque. The engine is mated to an eight-speed ZF transmission. BMW X4 will reach 60 mph in 5.2 seconds and complete the quarter mile in 13.9 seconds at 98.8 mph. From 60 mph, the X4 will stop in 113 feet.
The 2015 Audi SQ5 uses a 3.0 liter supercharged V6 making 354 horsepower and 347 lb-ft of torque. Like the BMW’s, it’s mated to an eight-speed automatic transmission. The SQ5 hit 60 mph in 4.4 seconds and powered through the quarter mile in 13.1 seconds at 104.2 mph. The braking distance from 60 mph was measured at 123 feet.
Porsche’s Macan comes with a 3.6-liter twin-turbo V-6 good for 400 hp and 406 lb-ft of torque paired with a PDK seven-speed twin-clutch automatic. The Porsche’s 4.2-second 0-60 mph time is the quickest of the bunch. Its quarter-mile performance of 12.9 seconds at 106.2 mph. Braking distance is 102 feet.
The only four-cylinder vehicle of this test, the Mercedes GLA45 AMG, is powered by an over-boosted 2.0-liter, turbocharged inline-four making 355 hp and 332 lb-ft of torque mated to a seven-speed dual-clutch automatic. From 0 to 60 mph, the GLA45 AMG needs 4.3 seconds and finishes the quarter mile in a comparison-best 12.8 seconds at 107.9 mph. The GLA45 comes to a halt in just 103 feet in the 60-0 test.
But which one is a better buy? Here is what MotorTrend has to say:
1st Place: Mercedes-Benz GLA45 AMG
Certainly not the most “mature” crossover here, the GLA45 AMG’s playful demeanor and serious performance cred earn it the gold.
2nd Place: Porsche Macan Turbo
The tremendously capable (and tremendously expensive) Macan Turbo misses out on first place by a nose—and about 20 grand.
3rd Place: Audi SQ5
That Porsche is nice, but if value were a larger part of the equation, the SQ5 might have shaken things up a bit more than it did.
4th Place: BMW X4 xDrive35i
The BMW X4 is neither a convincing coupe nor a true performance SUV.
