Bosch has an advanced self-parking system slated for 2019

Self-driving cars are the future of the auto industry, but there are many years and intermediate steps between now and driverless roads. Bosch made one of those important baby steps earlier this month when it unveiled its Home Zone Park Assist, which takes automated parking to the next level. The system works like this: a driver pulls up to where they'd normally begin to angle into a preferred parking spot. The driver then sets the start point and slowly drives the car into place so the system can learn the route. After the route is entered, the driver can let the car take control by either holding down a button inside the vehicle or on a smartphone app to engage the self-parking program from outside the car. Twelve ultrasonic sensors, a rear-facing stereo video camera, and four radar sensors work together to slot the car safely into or out of a spot perfectly every time. If you don't start in the same place every time that's okay, because the car can deviate from the original start and stop points by up to six and a half feet. The system can track up to 100 meters' worth of complex maneuvers, perfect for anyone tired of backing out of long, curvy, or steep driveways. Bosch says the system will be available in a few years but doesn't mention any specific models. Other companies have similar technologies, but they're not quite as advanced. The National Highway Traffic Safety Administration recently cleared a similar technology called Park Assistant Plus for use in the BMW 7 Series. BMW's technology allows drivers to move the car in and out of parking spaces with the key fob. Tesla's Summon feature allows the Model S and X to come when called up to 10 meters away. But Bosch seems to have pushed the boundaries of what autonomous features on cars can do. Besides superior distance, the really amazing aspect of Bosch's system is that it allows cars to sense obstacles within its path and make the decision whether to proceed with minor course adjustments or stop and wait for its owner. That's right, a decision-making car. Welcome to the brave new world. Related Video:

BMW i8 pitted against M4 in sibling rivalry track battle

We recently watched Auto Bild challenge the BMW i8 against the M4 in a German drag race of decide the quicker of the inter-brand rivals. The hybrid took a commanding victory in that fight. However, Autocar now has a new battle for the two coupes. The siblings are together again on the Castle Combe Circuit to find out which of them offers the more enjoyable experience at the track. Unfortunately, we don't ever get a perfect point of comparison in the video because host Steve Sutcliffe never does a full lap in anger with either of them to set a time. Instead, he focuses more on how the BMWs feel behind the wheel. Sutcliffe also admits midway through the clip that the i8's electric motor is out of juice to power the front axle's electric motor. That only leaves the hybrid with its 228-horsepower and 236-pound-feet-of-torque turbocharged three-cylinder to spin the rear wheels. Still, Sutcliffe spends ample time explaining the benefits and downfalls of driving these coupes. See where his opinion falls between the M4 as the traditional German sports coupe and the i8 as the new-school hybrid in the video, above.

AC Schnitzer's hotrod BMW 318ti remembered by MotorWeek

There are plenty of compact luxury cars available in the US today, including the Audi A3, BMW 2 Series, and Mercedes-Benz CLA-Class. In the '90s, the BMW 318ti tried to offer a similar mix of luxury at a reasonable price, but it never quite found much success in America. The 318ti looked like an E36-generation 3 Series in front but featured a stumpy liftback at the rear. The only engine available in the US was a four-cylinder. If you had the money, though, the aftermarket was ready to give you more power and more aggressive looks. AC Schnitzer dropped a bored and stroked 3.0-liter inline-six under the hood to create a pocket-sized hot rod, and MotorWeek took it for a drive. The model in this video was the promo car for AC Schnitzer's US importer, and it had every upgrade possible to show off what the German tuner's produced. Under the hood, the company installed an upgraded engine with 241 horsepower and 228 pound-feet of torque. For comparison, a US-spec M3 of the era had 240 horsepower and either 225 or 236 lb-ft, depending on the model year. AC Schnitzer also sharpened the 318ti with a suspension overhaul and short shifter. According to MotorWeek's tests, the mods got the hatchback to 60 miles per hour in 6 seconds and gave 318ti laudable handling. So much performance wasn't cheap, though. The upgrades on the promo car cost more than twice as much as the 318ti's base price. Watch this Retro Review to find out the massive amount you needed to pay to get M3 performance in a tiny package.
