2014 BMW 328d rated at 32/45 mpg

BMW still hasn't released official fuel economy numbers for its diesel-powered 2014 328d, but now, those mileage ratings have been posted on the EPA's FuelEconomy.gov website. As expected, the 328d is quite an efficient little machine, with the rear-wheel-drive sedan good for 32 miles per gallon in the city and 45 mpg highway. That even bests the 30/42 mpg of the smaller Volkswagen Jetta TDI.
The last time BMW offered a diesel 3 Series in our market, it was the six-cylinder 335d, which - while mighty quick and excellent to drive - was only offered as a rear-wheel-drive sedan and was rated at 23 mpg city and 36 mpg highway. For 2014, BMW will offer the 328d with optional xDrive all-wheel drive, though that reduces the fuel economy numbers to 31/43 mpg. Beyond that, the BMW will even sell you a 328d xDrive wagon, which nets the same 31/43 mpg rating, according to FuelEconomy.gov.
Look for the 2014 BMW 328d to hit dealerships this fall, and when it launches, it will be the only diesel offering in its class (until the next Mercedes-Benz C-Class arrives, anyway). Lexus and Infiniti will offer hybrid versions of the IS and Q50, respectively, but we've always had a taste for torque, and the 328d's 2.0-liter engine with 180 horsepower and 280 pound-feet of twist shouldn't disappoint.

2014 Dinan S1 BMW M5

The last time the Dinan name graced the pages of Autoblog, Michael Harley was waxing poetic about the S3-R BMW 1M Coupe, a car that still stands in his ranks as one of the best cars he's ever driven. And that wasn't just because it was, you know, amazing. It's because as far as tuners go, Dinan produces some seriously well-executed products. Harley said of the 1M, for example, "It was so fully formed and well-rounded that it felt like BMW itself had made it."
Eager to sample some of these wholly wonderful wares, I cleared a few hours in my Monterey Car Week schedule and booked a date with the S1 M5 you see here - the (current) daily driver of Mr. Steve Dinan, himself. But unlike the S3-R 1M the company tuned previously, the donor car in question here is vastly different and, if I'm honest, not as good. See, I adore the stock 1M in a way words cannot express, but the standard-issue M5... good as it is, there are indeed a few flaws.
But after driving the Dinan S1 M5 around the Monterey Peninsula, I can confirm two things. First, Harley's conclusion that Dinan builds products that feel 100 percent BMW-spec is absolutely true. And second, Steve and the gang haven't just created a tuned M5, they've built a better one.

Consumer Reports criticizes small turbo engines for misleading performance, fuel economy claims [w/video]

Consumer Reports has taken aim at at small-displacement, forced-induction engines, saying the powerplants don't manage to deliver on automaker fuel economy claims. Manufacturers have long held that smaller, turbocharged engines pack all power of their larger displacement cousins with significantly better fuel economy, but the research organization says that despite scoring high EPA economy numbers, the engines are no better than conventional drivetrains in both categories. Jake Fisher, director of automotive testing for Consumer Reports, says the forced induction options "are often slower and less fuel efficient than larger four and six-cylinder engines."
Specifically, CR calls out the new Ford Fusion equipped with the automaker's Ecoboost 1.6-liter four-cylinder engine. The institute's researchers found the engine, which is a $795 option over the base 2.5-liter four-cylinder, fails to match competitors in acceleration and served up 25 miles per gallon in testing, putting the sedan dead last among other midsize options.
The Chevrolet Cruze, Hyundai Sonata Turbo and Ford Escape 2.0T all got dinged for the same troubles, though Consumer Reports has found the turbo 2.0-liter four-cylinder in the BMW 328i does deliver on its promises.
