BMW X4 M40i leaks ahead of LA Auto Show

Leaked photos of the higher-performance BMW X4 M40i emerged today ahead of its expected debut at the 2015 LA Auto Show. The new model builds on the xDrive35i model, offering an extra 60 horsepower and 43 pound-feet of torque. The hotted-up X4 should use that power well. According to Auto Guide, it will hit 62 miles per hour in 4.9 seconds and should be limited to a top speed of 155 mph – a notable improvement over the existing xDrive35i, which takes 5.2 seconds to hit 60 and has a top speed of 130 mph. Expect the X4 M40i to be followed by an similar version using the X3's more versatile body style, both of which will use an eight-speed automatic and a more aggressive all-wheel-drive setup. Despite the "M" in its name, this is not a full-blown M car. Instead, it takes the same tack BMW has used for the M235i here in America, as well as the M50d models sold in Europe: higher performance over stock, without offering the full enchilada that is a proper M car. That explains the slightly more aggressive body kit, which isn't as sporting as that of a proper M car. On top of the new front and rear clips, there's a set of meaty 19-inch wheels that look to be wrapped in sporty Michelin Pilot Super Sport tires. In the cabin, an oversized M-branded steering wheel is the most notable addition. Naturally, we'll have the full range of details on the X4 M40i when it debuts in a couple of months in LA.

Pure black BMW i8 hydrogen fuel cell prototype on the track

Largely coated in matte black paint with just a few touches of dark blue contrast, the BMW hydrogen fuel cell-powered i8 prototype looks stealthy just sitting still. Now, that ninja-like styling is taking to the track in this video to prove that its performance doesn't come with much noise. The quiet hum of the tires and an odd whir from the rear are all that you hear coming. As this i8 prototype picks up speed around the circuit, the sounds that the drivetrain makes just get weirder. When moving slowly, you can pick out the usual whine that's expected from conventional electric vehicles. However at higher velocities, the coupe almost makes a noise like its constantly exhaling. Along with the recently unveiled BMW 5 Series Gran Turismo hydrogen-fueled concept, this sneaky looking i8 is part of BMW's technological push to become a greener automaker. The company is also prototyping a turbocharged engine with water injection and new plug-in hybrid powertrains. Although this low-slung coupe is by far the most attractive of that bunch. We might not be too far away from actually seeing this tech on sale on models bearing the Bavarian brand's roundel, either. Thanks to collaboration with Toyota, the company wants to have fuel cell components ready by 2020, and sales could start early in the decade. Hopefully all of the company's FCEVs look as menacingly great as this i8 by that time, though.

Cadillac CT5 vs. BMW 3 Series | How they compare on paper

Cadillac just introduced the CT5 sedan at the 2019 New York Auto Show, and it's set to replace both the larger CTS and smaller ATS in the brand's lineup. We have all the details and features for you, in addition to a deep dive with the car's chief engineer, but now it's time to see how it stacks up to the long-time standard bearer in this class: the BMW 3 Series. Now, the car is a bit larger than the completely new 2019 3 Series, but Cadillac says the 3 and the rest of the compact luxury sedan class is its target for this car. We'll dive further into this little conundrum later. This comparison will look at how these vehicles measure up on paper, as we haven't driven the CT5 yet. That will come later, but we're expecting it to be a proper sport sedan competitor with the 3 Series, since Cadillac is building it off GM's dynamically superb Alpha platform. Now let's get on with the comparison. Powertrains and performance Both of these sedans come standard with 2.0-liter turbocharged four-cylinder engines. The BMW four-pot is a bit more potent, coming in with 18 more horsepower and 37 pound-feet of torque more than the Cadillac. Here's our driving review of the BMW. The only upgrade engine for both available initially are turbocharged six-cylinders. BMW offers up its revised inline-six, while Cadillac offers a V6. These six-cylinders are both 3.0 liters. Cadillac bests the BMW in brute torque by 31 pound-feet, but BMW takes the horsepower prize, making 47 more ponies. It's hard to say which car will actually be faster to 60 mph — they'll probably end up being about the same once official numbers are out. This segment used to be one guaranteed to offer a manual transmission, but that's not the case anymore. Neither Cadillac nor BMW will offer a manual to start, but expect to see the stick shift return to higher performance models of each car. For now, they both get torque-converter-style automatic transmissions. One dimension that isn't going away from either anytime soon is rear-wheel drive. Both cars offer rear-wheel and all-wheel drive in every spec available. Fuel economy for the 3 Series is impressive at 30 mpg combined with the four-cylinder. We'll have to wait and see if Cadillac can challenge that figure with its less powerful engine. Size and practicality Here's where a lot of the confusion about the Cadillac CT5 sets in. The CT5 is a tad larger than the 3 Series in its exterior dimensions, but the interior specs are nearly identical.
