An embarrassment of riches this time as the 2013 BMW 750Li and Lexus LS 460 hit our garage on the same day. Some assignments are just more comfortable than others! But while both cars are luxurious, one felt much readier to cut it up on the road to my hands, and you might be surprised which.

A great Car Tech 101 in this episode, explaining the rather tricky relationship between horsepower and torque. We're conditioned to think about horsepower, but … Read more

AT&T, General Motors to sell 4G LTE-connected cars next year

BARCELONA, Spain--General Motors cars rocking their own 4G LTE connection will hit the road next year.

AT&T and GM's OnStar service unit struck a deal to bring millions of connected cars to the market, starting with the 2015 fleet, which comes out late 2014. GM said most Chevrolet, Buick, GMC, and Cadillac cars will get wireless connections.

It's the latest win for AT&T, which has been particularly aggressive in going after the connected car business, a lucrative one in which the company believes it can eventually generate a billion dollars in revenue. Furthermore, the … Read more

Automatica automatically updates contents over Wi-Fi

A Wi-Fi-enabled USB drive seems like an odd idea, yet the Automatica serves an excellent purpose in the car. Inrete, maker of the Automatica, sets up the device to automatically update content such as music or podcasts.

There are some limitations, however; for example, the Automatica only works if you have a USB port in your car. It may be useful in some other settings, as well, but in a car seems the most likely.

The Automatica would make the most sense for drivers who park their cars within reach of a home Wi-Fi network. Every time the Automatica makes … Read more

2013 Ford C-Max Energi moonlights as an electric car

For those not ready to jump feet-first into the electric-vehicle pool, the 2013 Ford C-Max Energi offers a toe-dipping experience, a chance to check the water temperature before committing to the deep dive. And after experiencing the C-Max Energi, any reservations about electric cars should be erased.

The C-Max Energi is a variant of Ford's C-Max Hybrid, a funky European-derived car abounding in sheer practicality. In our testing, the C-Max Hybrid achieved consistent low-40s fuel economy, while offering a large amount of versatile interior space.

Due to a larger lithium ion battery pack, the C-Max Energi sacrifices some of … Read more

Tesla, the Times, and how to drive an electric car

This week's Tesla versus The New York Times flap came to a climax yesterday when Tesla released the logs it promised on its Web site, and the newspaper responded with a point-by-point refutation.

Tesla's post says that New York Times environmental reporter John Broder misrepresented the Model S' performance. Broder argues that he was simply following advice from Tesla personnel during the drive.

The original New York Times story painted the Model S with a negative brush, but as I wrote Wednesday, a close reading of the article shows that the Model S operated exactly as you'd … Read more

Connected features abound in the 2013 BMW 750Li

The 2013 BMW 750Li may seem like the perfect luxury car, but it did not organize my financial portfolio for me. Nor did it shine my shoes. It did not even bother to buy me a winning lottery ticket. But those are about the only services it failed to perform.

The 750Li overwhelmed me with everything it did offer, from driving modes to connected features. It delivered on BMW's reputation for excellent handling and served as a superbly comfortable freeway cruiser. It abounds with tech from stem to stern, improving its fuel economy and entertaining the driver's every … Read more

Tesla releases logs on disputed NYT car review

Tesla, the electric car maker, has made good on its promise of releasing logs connected to the contested New York Times' review of its Model S.

In the review, published Sunday, the Times' John Broder criticized the Model S for range issues and for problems in low-temperature environments. Tesla's founder and CEO, Elon Musk, has wasted no time trying to discredit the review, claiming that Broder's account of what happened was not factual.

Here's a brief list of issues Musk gleaned from the logs:

Despite Broder saying that he called a flatbed truck after the Model S … Read more

Researchers develop a more accurate car navigation system

Driverless cars could get a big boost from a new system that researchers say will increase the accuracy of in-car satellite navigation systems by 90 percent.

Researchers say the system combines conventional GPS signals with data from sensors such as accelerometers and gyroscopes to determine a vehicle's position within six feet of its location, a dramatic reduction from the current margin of error of 50 feet. The system can be installed inexpensively in any vehicle, say researchers at Spain's Universidad Carlos III de Madrid, where the system was developed.

"We have managed to improve the determination of … Read more

Tesla, the Times, and the range war over the electric car

This week saw a war of words between Tesla's supporters, lead by CEO Elon Musk, and New York Times' environmental reporter John M. Broder. The issue in contention was the range of the Model S electric car during a typical East Coast winter, as detailed by Broder in the article "Stalled Out on Tesla's Electric Highway."

Broder's article could be taken as an indictment against the practicality of the Model S, but reading his account closely, I did not see anything that went outside of how I would expect an electric car to behave.
