How to charge up your BMW i3 with a Honda

Behold a cheaper version of BMW's range extender for its i3 plug-in. And it's brought to you by ... Honda? Sort of, if you take the approach that Gadget Review took when it looked for an alternative to ponying up the $4,000 or so for the gas-powered i3 range extender that comes from the factory. What was procured was a Honda portable generator for Home Depot for the experiment, which involved gassing the generator up in a parking lot, plugging in the i3 and going out for a cup of coffee. The result was that, after about a half-hour of charging, the i3 picked up about four miles of driving range. Not exactly revolutionary but it least a bit instructive. And given that Honda generators start at about $800, the idea, while clunky, is potentially cash-saving. Gadget Review briefly took the experiment one-step further by trying to run the generator inside the back of the car and plugging in, complete with a rigged-up ventilation system, but the host thought better of it once he realized that there'd be suffocation involved. Why this was never tried on the Nissan Leaf, we'll never know. Check out Gadget Review's five-minute video below.

2015 Dinan M235i First Drive

The first rule you learn about playing hide-and-seek is to wait until the seeker is out of sight before you move on to your next position. That feeling comes back to us as we're sitting in the Dinan-tuned 2015 BMW M235i on the twisty stretch of Route 152 near Gilroy, CA. Construction restricts the road to one lane before opening up to five miles of uninterrupted switchbacks. A local tipped us off to pull over and wait for traffic to clear, guaranteeing an open road and no risk of law enforcement seeking us out. Our first turn behind the wheel of the Dinan M235i started just a few miles north at the tuner's engineering and development center, located in an unassuming office park south of San Jose. Dinan conversions are known for being simultaneously subtle and awesome; an enhancement of products that already stand out in their respective classes. Dinan obtains its R&D cars through consumer channels, unlike some tuners that get early access to BMW's engineering for their own development projects. The development process is "reverse engineering," as technical director Casper van der Schoot describes it. Some development cars also come to Dinan through the generosity of its owner fan base. Customers hand over personal vehicles in exchange for discounted products. An M2 is already on order, and the Dinan engineers are on the edge of their seats waiting to take it apart. The Dinan treatment of the M235i increases performance without reinventing the dynamically sound package. As with other Dinan cars, the treatment on the M235i increases performance without reinventing the dynamically sound package. Approved dealers can install the Dinan parts, as can "anyone with a modest amount of technical aptitude," according to van de Schoot. Dinan's approach is to extract more of the best aspects of BMW products before supplanting stock parts with its own. That's why the M235i, like all Dinan products, comes with the eponymous Dinantronics engine control unit that remaps and finds more power from the stock inline-six-cylinder engine. A bespoke carbon-fiber cold air intake and stainless steel free-flow exhaust system add at least 15 more horsepower. The most significant alterations in the M235i's engine bay are a Dinan-rebuilt turbocharger and larger intercooler, which help increase total output beyond 440 horsepower. At this point you might wonder if all this untapped capacity is at BMW's disposal from the start, why does it take Dinan to release it?

BMW dismisses Tesla tie-up talk

Despite recent rumors to the contrary, don't expect to see much collaboration between Tesla and BMW in the near future. Based on some rather prickly statements from the German automaker, Elon Musk might have even burnt some bridges in Bavaria with his latest proclamations. The spat stems from Musk's recent interview with German magazine Der Spiegel where he discusses future collaboration with BMW on "battery technology or charging stations" and the possibility of a battery factory in Germany. But apparently, any future tie-ups are news to the Bavarian automaker. In an interview with the German business publication Wirtschafts Woche, an unnamed spokesperson for the company claims Musk said it all for PR value and swats down most of the statements. BMW has no intention of acquiring Tesla shares, and they aren't working together on any tech. There's not much chance for future cooperation on a battery factory in Germany, either. BMW believes that the cells can just as easily be purchased from suppliers, like other auto parts. The one slight concession is that the spokesperson said that the German automaker would be willing to supply Tesla with carbon fiber. That's not an exclusive offer, though, and the company is open to negotiate such a deal with any interested automaker.
