2015 BMW M3 squares off against Alpina D3 in gas vs. diesel throwdown

There was a time when diesel meant one of two things: This vehicle's owner either wants to save some money at the pump or needs to haul massive loads. It definitely did not mean that the owner of said machine wanted to drive fast, but that perception has slowly but surely been changing over the last several years, with automakers from Volkswagen and Ford to Audi and BMW offering spiced-up versions of their high-compression, turbocharged diesels.
It's that last automaker we mentioned that's the subject of the video you'll see down below. One bright-blue BMW M3 was procured by the Brits at Autocar, and it was lined up against a deep-black Alpina D3 (which we sadly can't buy in the US) in a spate of tests, including acceleration, stopping, sound and lap times on a closed circuit. The results, which we won't spoil for you, were enlightening, and were followed up by personal impressions from the man behind the wheel.
We know you're curious. All it takes to find out which of these 3.0-liter, twin-turbo-powered 3 Series variants came out on top is to scroll down below and watch. You know what to do.

BMW heads for the waves with Path 22 concept bike

BMW has been reminding us in the grandest of style recently of the serious clout it has in the classic motorcycle field. Most important is the R NineT that it put into production, but it's also been giving us a steady stream of enticing concept bikes, like the Concept 90 retro racer and the more recent Concept 101 custom bagger. And now it's showcasing another. This time, BMW Motorrad has taken a page out of the scrambler playbook with the Concept Path 22. Based on the R NineT, this concept bike is designed for surfers in impressive 1950s style. It features a single-side swing arm rear suspension, a classic circular headlamp, reprofiled tank and seat, studded tires, an oversized front wheel, longer fork travel, and a raised exhaust. It also has a unique paint job by Ornamental Conifer, and a pair of surf boards designed by Dyer Brand and mounted to a collapsible bracket on the side. Meant to showcase just one possibility for customizing the R NineT, the concept bike is named (and numbered) after one of Europe's premier surfing spots. It is being unveiled – appropriately enough – at the Wheels & Waves Festival in Biarritz, France. BMW Concept Path 22 – The Expression of Freedom. Munich/Biarritz. From June 11th - 14th 2015, the Wheels & Waves Festival celebrates for the fourth time a unique meeting of custom bikes, surfing and art in Biarritz. The festival is a great event that provides a straightforward opportunity for people to get together in a unique atmosphere and express their lifestyle of freedom and individuality. In this special setting, BMW Motorrad presents the BMW interpretation of a scrambler for the first time: the BMW Concept Path 22. Expression of a Lifestyle. The first scramblers in the 1950s were modified road machines with deep-treaded tyres, somewhat increased spring travel and a raised exhaust for off-road riding. These features gave the bikes a characteristic appearance that came to symbolise an attitude. "A scrambler is the perfect match for Wheels & Waves. It's the epitome of a motorcycle beyond established standards and conventions. Performance specifications are not so much of interest - style and originality all the more so. Scramblers express passion and are as varied as their owners. The Concept Path 22 is our own interpretation based on the R nineT. The latter is the perfect basis for a scrambler conversion", explains Edgar Heinrich, Head of BMW Motorrad Design.

Are future vehicular hacks inevitable?

Before the hack of the Uconnect system in a Jeep Cherokee resulted in a 1.4-million vehicle recall, the potential software vulnerabilities in vehicles were already a hot topic with Congressional inquiries and even proposed legislation in the US. As cars' interconnected systems gain the ability to go online, they become open to a host of new threats. Automakers are trying to stop this, but it might be too late to put the genie back into the bottle. Throughout 2015, the issue of software security in vehicles has become increasingly vital. For example, the recent Jeep case wasn't even the biggest hack this year. In February, a major flaw was discovered in the BMW Connected Drive service that allowed researchers to remotely lock and unlock the doors and potentially affected 2.2 million cars. The fix was an over-the-air patch for the problem. Automakers are actively working to fix the issues. Mercedes-Benz, BMW, and Audi reportedly are using encrypted connections and firewalls in their vehicles to prevent hacking. "Absolute, 100-percent safety isn't possible," Daimler spokesperson Benjamin Oberkersch said to Automotive News Europe. "But we develop our systems, tested by internal and external experts, so they're up to date." These vulnerabilities seem to be popping up more often. A successful hack took $14 in parts from Radio Shack in one case. There was also a 60 Minutes report earlier in the year about DARPA's ability to hack into OnStar to take control of a Chevrolet Impala. Experts aren't so sure companies can contend with hackers' advancement. "The difficulty for the carmakers at the moment is the question whether they can keep pace with advances in technology, and especially hacking technology," Rainer Scholz, executive director for telematics consultant EY, said to Automotive News Europe. "We seriously doubt they can." At this point, vehicle hacks are coming more from researchers looking for holes than from those with malicious intent. Still, the vulnerabilities are definitely there. It's up to automakers to keep patching the problems before they become dangerous to drivers.
