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.

BMW 4 Series spied with its future competition

BMW showed off its new 4 Series coupe in concept form at the 2013 Detroit Auto Show earlier this year, but it won't be long before we see the production model, evidenced by this modestly camouflaged prototype spotted testing. In case you forgot, the 4 Series serves as the replacement for the two-door versions of the BMW 3 Series, just as the upcoming 2 Series will effectively be the new version of the 1 Series coupe and convertible sold in our market.
This isn't our first glimpse of the 4 Series out testing, and we've even spied its droptop, Gran Coupe and too-hot M4 kin. We don't expect the final design to stray too much from the concept car seen in Detroit, albeit without the normal conceptual goodies like oversized wheels and with the overstyled front fascia toned down a bit. Our spy photographers even caught the 4 Series coupe hanging out with an Audi A5, giving us a good glimpse at how the two cars will stack up in terms of size and design.
It's still unknown exactly what engines will power the car when it comes to production, but since this thing is a derivative of the 3 Series, we expect the usual range of turbocharged four- and six-cylinder engines to be available, likely in 428i ad 435i guise (though, to be fair, the larger 640i coupe uses a 3.0-liter turbo engine, so there's even the potential for 440i nomenclature to work its way into the mix). We'll have to wait until the car officially bows later this year to know for sure.

BMW mulled ten, eight, and six-cylinder engines for i8 before going hybrid

There's little doubt that the 2015 BMW i8 is one of the most radical and groundbreaking performance cars this industry has seen in a long time. From its unique carbon-intensive construction to its 1.5-liter, three-cylinder and electric motor plug-in powertrain to its concept-car appearance, the flagbearer for BMW's new i venture challenges the very notion of what it takes to be a supercar.
Yet apparently the i8 almost didn't do that at all. Yes, it probably still would've had innovative assembly techniques, serious performance and come-hither bodywork, but according to a new report in the Telegraaf, it was very nearly a much more conventional beast, drawing its power from a V10 engine. According to the report, that line of development never got much beyond the drawing board, but BMW engineers then shifted their focus to both V8 and six-cylinder motivation, going so far as to build prototype cars. The higher cylinder-count engines were eventually dropped altogether after BMW decided to turn the i8 into a hybrid, with the six-cylinder reportedly nixed due to heat management and weight issues. In the end, of course, BMW went with the PHEV powertrain that offers a total system output of 362 horsepower and 420 pound-feet of torque - plenty of thrust for this lightweight, all-wheel drive coupe while still enabling an incredible 94 miles to the gallon on the EU cycle. Regardless of how it turned out, it's still fascinating to think that BMW didn't have a much firmer conceptual idea of what it was after when it started the i8's development.
Here at Autoblog, we're genuinely thrilled about this new generation of greener hybrid super- and hypercars, a movement spearheaded by the i8, Porsche 918 Spyder, Ferrari LaFerrari and McLaren P1. But even so, our inner-gearheads can't help but wonder what might have been had BMW pursued a more conventional i8, either in place of, or in addition to, the car they did build. What do you think?
