Ever notice that you your bladder seems to shrink when its cold outside? Apparently, the Toyota Prius feels your pain, and while we don’t have any good solutions to report for your own personal problems, Toyota has found an easy fix for its hybrid. Unlike previous generations of Toyota’s fuel saver, the new 2010 model won’t have an underperforming bladder when it’s cold outside.
Since its introduction back in 2001, Toyota has equipped the Prius with a synthetic fuel tank bladder that collapsed as gasoline was slowly pumped out of the tank and into the engine. Due to complaints that the last-gen car wasn’t able to take its full 11.9 gallon fuel allotment whenever the temperature was below 70-degrees, the third-generation Prius comes equipped with a more conventional rigid fuel tank made from lightweight resin. In order to retain its coveted low-emissions rating in California, the latest Prius also reportedly features an improved vapor-recovery system that will help reduce hydrocarbon emissions.

The next 1- and 3-Series cars from BMW, as well as the Z2 roadster, are rumored to be getting a new range of turbocharged three- and four-cylinder gasoline engines as part of BMW’s push to cut emissions and fuel consumption. Of the five powerplants reportedly in development, three are 1.35-liter three-cylinder motors developing between 163 hp and 241 hp, with the two 1.8-liter 4-cylinder engines putting out 273 hp and 321 hp, respectively. Sky Motoring says that the four-pots will be reserved for “more upmarket models.”
While a 3-Series with a 3-cylinder engine has a certain poetry, it does give one pause. If Sky Motoring’s numbers are correct, however, the top end 1.35-liter motor would put out 11 more horsepower than the current 3.0-liter in the 328i. That’s a lot of power for such little displacement, and with brand perception issues in the U.S., who knows if we would even get the engines – after all, we don’t get any of Mercedes’ CGI mills. From where we sit, though, the smaller, lighter engine with its commensurately fewer moving parts could also help bring the sticker price of the 1-Series down – one of the major factors that has prevented it from gaining traction in stateside showrooms.
In any case, the new BMW engines are said to be at least two years away, so we look forward to getting more clarifying information in the meantime. Hat tip to Owen!

Detroit traffic can be a real bear, but if a radical new rail line is approved, traveling between Michigan’s largest cities could become faster, less stressful and cleaner all at the same time. Worldwide Hydrogen Super Highways has come up with a design for an elevated railway that will utilize hydrogen-powered cars that can hit 200 mph. The rail cars would be built by Detroit automakers and use solar energy to charge their hydrogen batteries that will power a magnetic field for propulsion. The rails themselves would be stainless steel and run parallel to existing freeways.
The ambitious project, which could cost up to $2.3 billion ($15 million per mile, yikes!) would run between Detroit, Lansing and Ann Arbor. The rail lines would be built using only private funding, and the state of Michigan would get half the resulting profits. Additional funding would also come from leasing the rails for utility lines, advertising and, of course, by charging fares to passengers and freight.
The Michigan House is assembling a task force to study the proposal and will investigate its technological and financial feasability, as well as its impact on the environment. If the project is somehow quickly approved, construction could begin next year. Hydrogen-powered shuttles made in Motown sound pretty Buck Rogers to us, but we’re hoping there’s some substance here. As badly as Michigan could use the cash infusion and the influx of jobs, a $2.3 billion project of this magnitude could be a real winner if it actually works.

For all those interested in the progress of Chevrolet’s pivotal 2011 Volt, take note: Autoblog is taking part in a four-way live-chat with Jon Lauckner, General Motors’ Vice President Global Program Management tonight at 6:00pm EST.
The best part? You get to ask the questions. We will be joined in the chat by our esteemed colleagues over at Jalopnik and Cars.com’s Kicking Tires blog, so feel free to plug in with a question about the Volt or GM’s other alt-fuel initiatives in ‘Comments,’ and be sure to log back on to Autoblog at 6:00pm EST to join us in the live-chat!

Factory navigation systems might be a popular option on high-end vehicles, but there’s no denying that their astronomical price tag and lack of upgrades make them pale in comparison to aftermarket units available at a fraction of the cost. Automakers contend that the integration with the vehicle’s systems and the lack of unsightly cords are worth it, but when you consider that the technology was locked in three years ago, the choice is clear. Time to go to Best Buy.
Thankfully, Mercedes-Benz and Harman International have recognized the problem and are working on a two-piece solution to solve it. The modular system consists of a screen and a separate control unit mounted in the dash, allowing the system to be upgraded quickly and, more importantly, cheaply. The hidden “processing box” will handle all the heavy lifting, including the GPS, music storage and Bluetooth integration.
If the collaboration works, expect the modular sat-nav systems to be available in the second half of 2010 on eight Mercedes-Benz models.

Mercedes-Benz’ in-house tuning arm, AMG, has announced the horsepower wars are over, and the automaker is gearing up to implement a new range of technologies that will help reduce fuel consumption by 2012.
According to AutoTelegraaf, M-B will introduce start-stop technology on AMG models as early as next year, along with launching a direct-injection system based of the second-generation currently employed on the C350 CGI BlueEfficiency. The automaker has set an internal goal of reducing fuel consumption across its line-up by 30% in the next three years. While diesels and new engine technologies will go a long way to achieving that goal, Mercedes plans to begin reducing the weight of its vehicles through the use of more composite materials and other weight-saving assembly procedures.

The classic idea of aerodynamics gives rise to mental pictures of vehicles shaped like a smooth suppository. Reality turns out to be different, thankfully. Cars like the Ford Flex may appear weighty and as slippery to the wind as a barn while actually sliding through the atmosphere far more gracefully than one might guess. Aerodynamics studies by all automakers have led to the startling discovery that vehicles like the squared-off Flex actually manage their airflow quite well, thank you, and sanding off the corners hinders, rather than helps.
It’s the same over at Toyota where they’re calling strategically-placed folds “aerocorners.” While it’s long been held that a teardrop shape is the most aerodynamic, that’s not necessarily the case and a droplet-shaped vehicle isn’t terribly practical; just try to put that armoire in your first-gen Honda Insight. The worry that all cars will look the same when aerodynamicists start to take over is unfounded, as discoveries in the wind tunnel show that things aren’t always as they appear, and there’s plenty of room for uncommon design to still cheat the wind.
