BMW reveals M4 safety car with innovating water injection system [w/video]

Racing series don't just pick their safety cars at random, or use just whatever car is lying around. These days the car that sets the pace at the front of the pack is typically provided through consideration by a sponsor. In the MotoGP series, that's BMW and its M division, which have served up the Official Car of MotoGP since 1999. What you're looking at is the latest, and it packs some innovative technology on board. Aside from the matte black wrap with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and emergency equipment, this BMW M4 coupe packs a new injection system under the hood. Only instead of injecting fuel, it injects water into the combustion chamber – something that wouldn't usually be recommended, but BMW insists actually aids in the combustion process. The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better. The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent. Whether that eight percent is worth the added weight of the system – particularly with water pump and a 1.3-gallon tank in the trunk – is up for debate. But we'd imagine that the Bavarian engineers have weighed very carefully. Of course there's also the matter of refilling the water tank, which BMW says would be carried out whenever the safety car is refueled, but in real-world conditions would only necessitate attention once every five top-ups at the gas station. By now you might have guessed that BMW probably didn't develop this system just for the MotoGP safety car, and isn't planning on keeping it confined to the racetrack. Instead it's being tested and demonstrated on the safety car before being rolled out on production models in the future.

2016 BMW X5 xDrive40e Review [w/video]

BMW is no stranger to electrification. The company put the world on notice with the launch of its innovative i sub-brand. But the lessons learned from the i3 and i8 aren't limited to these small-volume cars. The more mainstream X5 xDrive40e impresses with lessons learned from i, all without compromising the SUV's character. The combination of a 2.0-liter, turbocharged four-cylinder engine with an electric motor is good for 308 overall horsepower and 302 pound-feet of torque. Sure, 240 hp and 260 lb-ft come from the four-cylinder engine alone, but the electric motor – integrated within the ZF eight-speed automatic transmission's housing – chips in a maximum of 111 hp and 184 lb-ft of torque. The 9.2-kilowatt-hour lithium-ion battery can sock away enough electricity to drive up to 14 miles on a single charge and will recharge at your average 110-volt socket in about seven hours. Of course, the battery pack and electric motor are a big weight penalty. At 5,220 pounds, the xDrive40e is 430 pounds heavier than the standard xDrive35i. Still, the gas-electric powertrain hustles this husky X5 40e to 60 miles per hour in just 6.5 seconds, less than half a second slower than the 35i. The stopwatch figures are complemented by the best fuel economy of any gas-powered X5, at 56 miles per gallon equivalent and 24 mpg combined. Only the diesel X5 xDrive35d is more efficient, at 27 mpg. But achieving top fuel economy in the 40e isn't as simple as going easy on the throttle. Perhaps more than any vehicle we've tested recently, understanding how all the X5's systems work together is crucial to eking out the most mpgs. The xDrive40e's Drive Dynamics Control will be familiar to anyone that's driven a recent BMW. Eco Pro, Comfort (the default mode), and Sport make the same adjustments to the throttle response, steering weight, and dynamic damper firmness as they do in a standard X5. But in the xDrive40e, they also impact the way energy is recaptured. Comfort/Save offers the best blend of fuel efficiency while achieving maximum energy recapture. Sport mode's aggressive energy recovery is the fastest way to recharge the battery on the go. When it's working, there's a sensation similar to gently stepping on the brakes, though you actually aren't doing anything – this is a familiar experience to the way most EVs use regenerative braking. Comfort mode reduces this effect, and in turn how much energy is recaptured.

This family has a trio of beautiful BMW E28 5 Series

The Caccavo family is not like yours. They're actually far, far cooler. Rather than dad driving a pickup, mom piloting a crossover and son getting about in a clapped-out compact, each member of the family has their very own second-generation BMW 5 Series. Father Dean's M5, mom DonnaRae's 528e and son Austin's 535is were, remarkably, all purchased for under $10,000, after the family made a maximum-price rule for its cars. The E28 obsession all started innocently enough, with Dean's M5. Shortly after that, DonnaRae snapped up the 535is. When it came time to buy a car, his parents told him he'd need to get a job and make the purchase on his own. He agreed, under one condition – that he was able to buy his mom's 535is. Once the deal was said and done, DonnaRae found she'd acquired the E28 bug, and promptly bought herself the 528e. Petrolicious has the entire story on the Caccavos and their E28s, available in its latest installment. Check it out.
