Top Gear drag races the BMW i8 and M4 to decide the future

The BMW M4 and i8 represent two every different expressions of the performance car. The M4 relies on its turbocharged six-cylinder combustion engine to spin the rear wheels. Conversely, the i8 packs a turbo three-cylinder and electric motors for its cutting-edge all-wheel drive system. Top Gear is the latest publication to put the pair together to find out which ethos is quicker. We saw Germany's Auto Bild hold a similar race last year, and the i8 scored a clear victory there. We don't want to spoil the winner of Top Gear's attempt, but we can tease that this sprint ends in a photo finish. Pick your favorite, and then watch the video to see which performance coupe takes the checkered flag. Related Video:

Toyota's Psy-style Waku-Doki ad inherits Japan's bizarre ad crown

A new Japanese Toyota ad featuring crisply suited businessmen driving into the jungle only to segue into a Psy-style music-video dance-off with a gorilla and natives is the latest car commercial to go viral. Jungle Wakudoki is the newest installment in a grand tradition of bizarre ads from the island nation that are by turns hilarious, head-scratching and occasionally even frightening.
Let's face it: My people are weird.
I'm half-Japanese and take suitable pride in my Asian roots, but even I can't figure out what's been slipped into the water coolers of the country's ad agencies much of the time - or the nation at large, for that matter. From Japan's ubiquitous obsession with all things adorable (kawaii) to its offbeat sense of humor and its bizarrely perverse and violent tentacle porn, it's clear there's a lot going on in the culture, and only some of it bubbles up to the surface in its marketing efforts. Much of the strangest and most amazing ads are for non-transportation products (e.g. laundry soap, snacks, energy drinks), but the automotive space has its fair share. This latest Toyota ad had me trawling YouTube for a common theme, trying to make sense of why these spots are the way they are. Scroll down to watch the Toyota ad in question as well as a bunch of other examples of Japan's most bizarre car-related ads and see if you can't find the thread that runs between them. Is it just that something's being lost in translation? Have your say in Comments.

Tougher than steel: Wood pulp could make lighter auto parts

KYOTO, Japan — The global push among carmakers to make ever lighter vehicles is leading some auto suppliers in Japan to turn to what seems like an unlikely steel substitute — wood pulp. Japanese researchers and auto component makers say a material made from wood pulp weighs just one-fifth of steel and can be five times stronger. The material - cellulose nanofibers — could become a viable alternative to steel in the decades ahead, they say, although it faces competition from carbon-based materials, and remains a long way from being commercially viable.> Related: Jay Leno drives the Renew cannabis car — hemp you can't dent Reducing the weight of a vehicle will be critical as manufacturers move to bring electric cars into the mainstream. Batteries are an expensive but vital component, so a reduction in car weight will mean fewer batteries will be needed to power the vehicle, saving on costs. "Lightweighting is a constant issue for us," said Masanori Matsushiro, a project manager overseeing body design at Toyota. "But we also have to resolve the issue of high manufacturing costs before we see an increased use of new, lighter-weight materials in mass-volume cars."A NEW PROCESS Researchers at Kyoto University and major parts suppliers such as Denso Corp, Toyota's biggest supplier, and DaikyoNishikawa Corp, are working with plastics incorporated with cellulose nanofibers — made by breaking down wood pulp fibers into several hundredths of a micron (one thousandth of a millimeter). Cellulose nanofibers have been used in a variety of products ranging from ink to transparent displays, but their potential use in cars has been enabled by the "Kyoto Process," under which chemically treated wood fibers are kneaded into plastics while simultaneously being broken down into nanofibers, slashing the cost of production to roughly one-fifth that of other processes. "This is the lowest-cost, highest-performance application for cellulose nanofibers, and that's why we're focusing on its use in auto and aircraft parts," Kyoto University Professor Hiroaki Yano, who is leading the research, told Reuters in an interview. The university, along with auto parts suppliers, are currently developing a prototype car using cellulose nanofiber-based parts to be completed in 2020.
