Both the new Juke and X-Trail will go on sale this July

Nissan’s stylistically contentious Juke is one of those "hate it or love it" vehicles. With its odd headlight treatments and strange design elements, the Juke is definitely for a specific taste. Now Nissan has unveiled both the redesigned Juke for 2015 and the all new, more straight forward X-trail. While the new Juke benefits from a series of design enhancements, new engine offerings and some technological revisions, the new X-Trail gets a complete ground up redesign.  Read More

Honda, the world’s largest motorcycle manufacturer, has announced a new motorcycle – the 750 cc NM4 Vultus – and it's a bold departure from tradition with anime/manga styling, a "fighter pilot" feet-forward riding position, an ultra-low seat and advanced electronic rider assistance to make it easier to ride. This is a motorcycle aimed at the next generation of motorcycle enthusiast raised on video games and a different visual vocabulary. If you are a traditionalist, you'll probably hate it.  Read More

WRX in its native environment, sliding around a corner on a dirt road

The Subaru WRX has always been a touchstone for rally car performance in a street legal car with its fast handling, turbocharged acceleration and hefty hood scoops. Subaru's long-awaited refresh adds a six speed manual or automatic gearbox, new styling, and bids farewell to the five door hatchback version.  Read More

Now here's a motorcycle with a difference. Alessandro Tartarini, son of Italjet founder Leopoldo, this week used the EICMA motorcycle show to present a new motorcycle concept. The aptly named Brutus (not to be confused with the existing Brutus electric motorcycle), is billed as "the SUV of motorcycles," runs a fuel-injected, 45 bhp, 750cc, single-cylinder engine with a CVT and optional reverse gear and weighs in at just under 220 kg (485 lbs) – about the same weight as a BMW 1200 GS or Ducati Multistrada. So does this genuinely represent a new genre of motorcycle?  Read More

Honda's new continuously variable transmission is coming to mid-sized cars

Honda has long championed the continuously variable transmission (CVT) and while this has in the past been largely a technology suited to small cars and even scooters, the Japanese car giant is now thinking bigger.  Read More

In a move that should see the humble agricultural equipment of the future both cleaner and more efficient, Oerlikon Graziano - a supplier to the likes of Ferrari and Lamborghini - has come up with an innovative a range of transmissions, including a mechanical continuously variable transmission (CVT) for small tractors. Released at Agritechnica in Germany last month, these new drive-trains are claimed to provide higher road speeds and be easier to operate so that the equipment can get to its work site much quicker without the need for a float or trailer.  Read More

Honda has outlined its next-generation technology for automobiles at the Tokyo Motor Show. "Earth Dreams Technology" is a broad revamp of engine and transmission technologies with which the company aims to achieve ambitious, industry-leading fuel efficiencies for every category within three years, while simultaneously setting a timeline of 2020 to reduce by 30% CO2 emissions for all products sold worldwide, relative to emission figures for 2000.  Read More

BMW's Concept C Maxi-scooter

While the European motorcycle industry is in crisis due to dramatically falling sales, BMW is moving in the opposite direction thanks to its loftier perspective of the mobility (as opposed to motorcycle) industry. After years concentrating on larger capacity two wheelers, it is moving into the scooter field. Having already shown an electric version of its ultra-safe C1 scooter, plus several MINI scooter concepts in recent weeks, BMW Motorrad yesterday unveiled a maxi scooter concept. Two premium scooters will be derived from the concept vehicle in the near future and there’s also an electric version being investigated.  Read More

The D-Drive: it could be a gearbox revolution, if only people could understand the thing!

Ready for a bit of a mental mechanical challenge? Try your hand at understanding how the D-Drive works. Steve Durnin's ingenious new gearbox design is infinitely variable - that is, with your motor running at a constant speed, the D-Drive transmission can smoothly transition from top gear all the way through neutral and into reverse. It doesn't need a clutch, it doesn't use any friction drive components, and the power is always transmitted through strong, reliable gear teeth. In fact, it's a potential revolution in transmission technology - it could be pretty much the holy grail of gearboxes... If only it wasn't so diabolically hard to explain. We flew to Australia's Gold Coast to take a close look at the D-Drive - and it looks to us like Durnin has pulled a rabbit out of his hat. Check out the video after the jump and see if you can work out if there's a catch.  Read More

There is a surprisingly close match between the energy storage requirements of an urban bu...

It seems that the lessons learned in developing a mechanical KERS system for F1 may yet hold the key to a low-cost, high-efficiency hybrid system particularly suited for the stop-start patterns of buses, which are quite similar to the distances between capturing and delivering energy of those of a race car. Torotrak will deliver a paper at the SAE Commercial Vehicle Congress in Illinois next week showing how flywheel KERS for buses can offer more than 30 percent fuel saving over the London bus test cycle, yet package around an existing transmission.  Read More
