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.

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.

2013 BMW M3 Coupe Lime Rock Park Edition

Sic Transit Gloria
I like difficult cars. I like turbo "moments," dramatic weight distribution, low-grip, peaky power delivery, and overly quick steering, along with ultra-short wheelbases and any number of other non-racecar-perfect dynamic foibles. I love the newest generation of BMW cars and engines - all turbo'd up with tons of torque and power everywhere in the rev range, too. But what I think the enthusiast community will miss when this 2013 M3 Coupe becomes the 2014 M4 Coupe - replacing its idiosyncratic, small-displacement, revvy V8 for something like a triple-turbo, directly injected, inline six-cylinder powerhouse in the process - is the work it takes to drive the car fast and perfectly. Sometimes small flaws just make things better; my mistress' eyes are nothing like the sun, and all that.
The idea of this E92 M3 going away then, magnified by the loss of the M3 badge for the coupe, is at best bittersweet for me. This generation of M car is already surpassed in terms of raw thrills by the better-than-ever Mercedes-Benz C63, a car that doesn't ask its driver to sacrifice low-end grunt or the very latest in amenities in return for stellar backroad performance. Yet any time I've been lucky enough to lap a track in the M3, it has quickly become clear that the Bimmer is the better on-edge tool. With the freedom to wring the neck of the 4.0-liter V8 and room to exercise the lovely balance of the car, the E92 is hard to match (even six years after its debut).
