Thermal imagery of BMW M4 DTM pit stop is red hot

A pit stop is a pit stop, right? The race car pulls in, the crew changes the tires, pumps in some fuel, maybe swaps out a busted body panel or squeegees the windshield, and off it goes for another heat. Only pit stops have become the focus of news lately for a number of reasons, whether it's because of mishaps (like the ones that prompted F1 to ban mid-race refueling), new time records (due largely to said ban) or interesting new ways to film the fast-paced action.
A few weeks ago we brought you footage of an IndyCar pit stop filmed from multiple angles courtesy of Google Glass. Now BMW has released a brief clip of one of its M4 DTM racers coming in for fresh rubber, all filmed by infrared camera. Its the kind of technology BMW uses to help optimize its German touring cars for competition, and now the Bavarian outfit has released some footage for fans to enjoy.
The resulting thermal imagery gives you an idea of how hot the car runs (and where the heat is emanating from), how warm they get the fresh rubber before they get it onto the car, and what kind of temperatures the pit crew is subjected to. Look closely enough in the 25-second video below and you'll even see the heat sputtering out of the exhaust pipes as the M4 downshifts into its pit box. (Just don't try adjusting your speakers, the clip is without audio.)

BMW i3 starts near $35,000; NA first deliveries January 2014

While in Germany at the first early pre-production drives of the hotly anticipated BMW i3, BMW people finally hinted at a price ballpark. Numbers being tossed around by pundits have actually been pretty close to what BMW is discussing internally - between $35,000 and just over $40,000. We have been assured now that the base price, should one choose to buy and not lease in the Euro zone, is just over 35,000 euro, with some big taxes included in that price. In the US, the starting price for the fully EV plug-in version should be $34,500 or right thereabouts. In addition to new pricing, we've also gotten our best-yet look at the i3, with the freshly uncovered spy shots you see here.
European deliveries begin in November of this year for the fully electric version of the rear-wheel-drive i3 with 168-horsepower and 184 pound-feet of torque. The e-motor mounted over the rear axle is supplied with energy by the 22-kWh lithium-ion battery pallet under the passenger compartment. Recharging happens in any of three ways: public or personal garage plug-in charge station (garage version not included in the price), the onboard system's Pro Eco mode that adds resistance to the drivetrain in a type of rolling brake energy recuperation, or through the normal brake energy and off-throttle coasting regeneration more common to EVs. Range on a full charge of this drivetrain is said to be upwards of 100 miles under hyper-miling conditions.
Perhaps the best bit of news is that the alternative, range-extending, two-cylinder 600cc engine supplied by BMW Motorrad for the hybrid version of the i3 - mounted in the rear together with the e-motor - will add only 2,000 euros in Europe and about $2,000 in the US. This is a range-doubling solution that could have brought a much higher price gouge, so thank you, BMW. The hybrid e-drive i3 version arrives a couple months after the full-EV launch version. Remember that, unlike the very similar system for the Chevrolet Volt, the system in the i3 supplies no mechanical torque to the driven axle and is only used as a generator (a system BMW first used last year in the 1 Series-based Active ). The US is seen as the clear number one market for the i3.

2015 BMW M3 Sedan

BMW's all-new M3 Sedan is dynamically nearly identical to its two-door M4 Coupe sibling: a stopwatch reveals that both are sub-four-second cars to 60 miles per hour, a racetrack proves that the mechanical twins are equally as adept on a road course and a full afternoon of driving on public roads demonstrates that each possesses talented everyday adaptability.
Yet after driving both BMW models back-to-back over two full days in Portugal, it's clear there are a few noticeable differences, both objective and subjective, that don't require instrument testing to reveal. All it takes is a few hours behind the wheel of both cars to conclude that one is slightly more agile, and the other a bit more twitchy. One has better outward visibility, while its counterpart is unquestionably more convenient.
It is the little things - subtleties attained through seat-of-the-pants observations - that eventually allow me to choose a favorite.
