The 570-hp AC Schnitzer ACL2 Concept tries to one-up the M2

AC Schnitzer's new ACL2 concept aims to outdo the BMW M2 at the Geneva Motor Show. To out-muscle the latest M car, the German tuner starts with an M235i and installs the M4's 3.0-liter inline-six. The company also turns up the power to 570 horsepower – a healthy upgrade over 365 hp from the M2's 3.0-liter. The power bump lets the ACL2 reach 62 miles per hour in 3.9 seconds and hit a top speed of 205 miles per hour, AC Schnitzer claims. Those figures make the coupe a few tenths quicker than the M2's 4.2-second to 60 mph sprint, but BMW limits its creation to 155 mph. AC Schnitzer's long list of upgrades makes the impressive performance possible. To get the most out of the engine, the company installs a carbon fiber intake. It also replaces the most of the exhaust, including the downpipe, catalytic converter and tailpipes. Carbon-ceramic brake discs make sure a driver can control so much power, and the company fits a fully adjustable suspension to aid handling. The ACL2's body is too loud for our tastes even through the subdued dark green paint, but the extensive use of carbon fiber parts should keep weight down. AC Schnitzer adds a road-scraping front splitter with canards at each corner. The rear has a similarly aggressive diffuser and huge wing. The wider fenders also add 5.5 inches to the coupe's width, and 20-inch wheels sit underneath them. The ACL2 doesn't get to challenge the M2 on the Autobahn yet because AC Schnitzer says it's just a concept. The coupe exists simply for the company's product development. However, if you want to put all of these bits together, the final cost would be 149,000 euros ($161,500 at current exchange rates), the tuner claims. Related Video:

Car Hacking 101: Here's what motorists should know [w/video]

Cars are nothing more than computers on wheels. As such, they're vulnerable to hackers. Most people who work within the auto industry have understood this for years, but for the broader American public not paying as close attention, three storylines emerged recently that underscored this new vehicular reality. First, German researchers found a flaw in BMWs remote-services system that allowed them to access the telematics units in vehicles. Then, a 60 Minutes report demonstrated that researchers could remotely infiltrate a Chevy Impala and override critical functions, like acceleration and braking. Finally, a US Senator released a critical report (see video above) that found almost all automakers are unprepared to handle real-time hacks of their vehicles. Those reports come on the heels of two previous instances in recent months when researchers demonstrated the capability to hack cars. All this news can be disconcerting. If you're late to the concept of car-hacking and wondering how this is possible, we've got you covered. Here's your quick primer on what you need to know. 1. How Did My Car Become A Computer? On the outside, cars haven't changed all that much over the past couple of decades years. On the inside, however, the amount of electronics and software has dramatically increased. Most new cars contain more than 50 microprocessors known as electronic control units. These ECUs control everything from airbag deployment and navigation systems to throttle control and braking, and they're usually connected to each other on an internal network called the CAN bus. 2. What Exactly Is Car Hacking? Depends who you ask. Automakers might consider anything that alters the car from its state of manufacture as a 'hack.' For example, if you're chipping the engine – re-calibrating those ECUs to increase your horsepower – some people might consider that a hack. But in the context of the recent news reports, security experts are focused on unwanted, unauthorized cyber intrusions into a vehicle. Once inside your car, prospective attacks could range from minor things like eavesdropping on conversations via an infotainment system and unlocking car doors to major concerns, like overriding driver inputs and controlling braking, steering and acceleration. 3. How Is This All Possible? Any part of the car that communicates with the outside world, either via a remote or direct connection, is a potential entry point for hackers.

BMW i8 will be first production car to use Gorilla Glass

What do smartphones and the BMW i8 have in common? Glass. Scratch-resistant Gorilla Glass, that is. The i8 will be the first production car to use the chemically hardened material, which is more durable, lighter and provides more sound deadening than conventional laminated automotive glass. We thought it would be a natural replacement for windshields, but, according to Autoweek, BMW said it will be used for the rear window for sound deadening purposes. The Gorilla Glass will still be laminated, with two 0.7mm thick layers of it sandwiching an acoustic sheet, reports Autoevolution.
BMW reportedly claims the i8 will weigh less than 3,285 pounds, and to offset the heavy hybrid powertrain to reach that goal the automaker has implemented lightweight materials normally not found in mass-production automobiles. With a carbon fiber reinforced plastic (CFRP) monocoque used for both the (relatively) pedestrian i3 and the upscale i8, it's not surprising BMW was also the first to jump onto Gorilla Glass, especially given the timing of a report that a high-end automaker would introduce it within the year.
