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.

BMW to follow Honda back into F1?

The economic downturn wrought devastating effects on motor racing. Formula One alone lost half its engine suppliers when Honda left at the end of the 2008 season, and both BMW and Toyota followed at the end of 2009. But things are looking up again. Cosworth may have dropped out this season, reducing the engine suppliers to three: Ferrari, Renault and Mercedes, the latter of which admits that it may have left had the engine formula not changed. But Mercedes has stayed and is dominating the championship. Honda is coming back next season. And word around the paddock is it may not be the only one.
According to Giancarlo Minardi - founder of the team now known as Scuderia Toro Rosso - BMW engineers have been conspicuously spotted lately at F1 test sessions and grands prix, lending to speculation that the new engine regulations may entice the Bavarian automaker back into the series. According to Minardi, BMW's marketing division is pushing for the automaker's return to F1, with the board slated to make a decision in May. BMW would be more likely to consider an engine-supply deal rather than taking a team over like it had with Sauber, but with which team or teams it might collaborate remains a big question mark at this point.
As if that's not enough, Ford is said to be considering taking over Cosworth's aborted V6 turbo engine program to take both outfits back into the sport as well. Cosworth supplied F1 engines under the Ford banner for years, but returned under its own name for four seasons from 2010 through 2013 before shuttering its program to develop an engine to meet the new regulations adopted this season.

2014 BMW 740Ld xDrive does diesel in a big way

Slowly but surely, BMW is expanding its lineup of diesel-powered models here in the United States. In addition to the 328d sedan and wagon, 535d sedan and X5 xDrive35d crossover, we now have this, the BMW 740Ld xDrive (not to mention the refreshed 2015 X3 xDrive28d that also makes its debut here in Chicago). As its name - and the photos above - suggest, this means BMW is offering diesel power in its flagship, long-wheelbase 7 Series sedan, set to directly compete with the likes of the excellent Audi A8 TDI.
Under the hood is BMW's familiar 3.0-liter turbocharged diesel inline-six, delivering 255 horsepower and 413 pound-feet of torque, all of which is sent to the road via the company's xDrive all-wheel-drive system and ZF eight-speed automatic transmission. That torque thrust is available straight away from 1,500 rpm, and BMW says the 740Ld xDrive will sprint to 60 miles per hour in a very respectable 6.1 seconds. Official fuel economy estimates haven't been released yet, but we expect the car to net highway fuel economy ratings in the mid-30 range.
The 740Ld xDrive arrives in BMW showrooms this spring, priced from $82,500, not including $925 for destination. We're pretty stoked to drive it. But in the meantime, have a look at fresh images of the big sedan live from the Chicago Auto Show, above.
