The one where we give you real car-buying advice | Autoblog Podcast #495

On this episode, Mike Austin and David Gluckman dive into some useful advice for people searching for a good used car, something David has been dealing with lately. They also talk about what they've been driving lately (Mike took a road trip in our long-term Fiat) and answer some Spend My Money requests from listeners looking for advice. And we have listener questions and comments to discuss, so thanks for sending those in. The rundown is below. Remember, if you have a car-related question you'd like us to answer or you want buying advice of your very own, send a message or a voice memo to podcast at autoblog dot com. (If you record audio of a question with your phone and get it to us, you could hear your very own voice on the podcast. Neat, right?) And please send trivia questions! You'll get the honor of stumping your fellow listeners, and we'll thank you too. Autoblog Podcast #495 The video meant to be presented here is no longer available. Sorry for the inconvenience.

BMW reveals M4 safety car with innovating water injection system [w/video]

Racing series don't just pick their safety cars at random, or use just whatever car is lying around. These days the car that sets the pace at the front of the pack is typically provided through consideration by a sponsor. In the MotoGP series, that's BMW and its M division, which have served up the Official Car of MotoGP since 1999. What you're looking at is the latest, and it packs some innovative technology on board. Aside from the matte black wrap with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and emergency equipment, this BMW M4 coupe packs a new injection system under the hood. Only instead of injecting fuel, it injects water into the combustion chamber – something that wouldn't usually be recommended, but BMW insists actually aids in the combustion process. The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better. The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent. Whether that eight percent is worth the added weight of the system – particularly with water pump and a 1.3-gallon tank in the trunk – is up for debate. But we'd imagine that the Bavarian engineers have weighed very carefully. Of course there's also the matter of refilling the water tank, which BMW says would be carried out whenever the safety car is refueled, but in real-world conditions would only necessitate attention once every five top-ups at the gas station. By now you might have guessed that BMW probably didn't develop this system just for the MotoGP safety car, and isn't planning on keeping it confined to the racetrack. Instead it's being tested and demonstrated on the safety car before being rolled out on production models in the future.

Toyota-BMW sports car to gain all-wheel drive, supercapacitors?

Sales of salt are skyrocketing following the latest rumor of the planned joint-venture sports car from Toyota and BMW. The whisperings indicate that project will spawn both a replacement for the BMW Z4 and a long-awaited Toyota Supra successor based on the FT-1 Concept shown above. Word is that the new cars will feature front-engine, all-wheel-drive layouts with plug-in hybrid technology. This news would appear to run somewhat counter to earlier reports that BMW and Toyota are teaming for a six-figure hybrid supercar.
According to Autocar, the project will benefit from the experience Toyota gained with the TS030, its hybridized Le Mans prototype. The evidence for this is, of all things, a Toyota Yaris - in particular, the Yaris Hybrid R that was shown at the 2013 Frankfurt Motor Show last September. That car used a 300-horsepower, 1.6-liter gas engine, while a pair of 60-horsepower electric motors provided all-wheel-drive push (an additional motor also sent additional juice to the front axle). The 414-system-horsepower drivetrain used supercapacitors in place of the traditional lithium-ion batteries of traditional hybrids.
For the production sports cars, Autocar claims that the Yaris Hybrid R's setup will serve as the basis for the new powertrain, although it won't be a direct carryover. Instead, a 2.0-liter BMW engine will be paired with Toyota-designed, BMW-built motors.
