Well now, 27(35i)->33(28i) up from 30 IS meaningful, point for the 28i. But how the hell can this heavier, taller, AWD vehicle with the exact same mechanicals match the 328i for highway fuel economy post EPA revision? Something stinks.
Quote from C/D:
Update 8/29: The EPA has released its estimates for BMW’s new X1 and the Bavarians’ 2.0-liter turbo four–powered models are more-efficient than BMW predicted. The rear-drive sDrive28i is rated for 24 mpg in the city and 34 mpg on the highway, which is 1 mpg more on the highway than BMW claimed. The all-wheel-drive xDrive28i is good for 22/33, 3 mpg better on the highway than BMW estimated. The turbocharged 3.0-liter inline-six–powered xDrive35i is certified for 18/27, precisely as BMW foretold.
