Old vs. new debate gets new life with $25,000 Fiesta ST vs. E46 M3 showdown

You know who you are. There's probably a few of you reading; the ones that say, "Why would I spend $27,000 on a new Mazda MX-5 when I could get a used Chevrolet Corvette with more power." Yes, we're talking to you, used car proponents. While it is a fair argument, it's not like used cars don't come with drawbacks of their own, though.
In an attempt to put this new-versus-used argument to bed once and for all, Matt Farah of the The Smoking Tire has picked up a pair of $25,000 cars - a used, but lightly modified, 2003 BMW M3 and a 2013 Ford Fiesta ST. Naturally, there's a comparison.
Farah, as he's wont to do, does get into the nitty gritty of what each car is like to drive, and discusses the merits of used and new-car shopping. But as he rightly points out while testing the M3, "So, it is a good car. But like any used car, it really does depend on the individual car."

Recharge Wrap-up: EV charging at IKEA, Tesla Model M just rendering

Despite rumors, Tesla will not be producing a "Model M" electric motorcycle. After a rendering of a Tesla motorcycle concept by a designer named Jans Slapins began circulating online, some folks mistakenly thought it was something Tesla intends to build. Slapins, though, has no relationship with Tesla, nor has he claimed to. As cool as it could be, Tesla hasn't stated an interest in producing an electric two-wheeler, and, as Green Car Reports explains, Tesla's batteries don't lend themselves to the size and shape of a motorcycle the way, say, Zero's do. Read more at Green Car Reports. Piaggio and KTM are partnering to develop an affordable electric commuter vehicle. The EU is funding the project in the hopes that commuters would choose such a vehicle over polluting, traditionally powered vehicles for their daily drives. The initial plan is to create two four-wheeled tilting vehicles for demonstration purposes. The two manufacturers will also receive support from Bosch and several universities.

CCH2 involves storing the fuel on board at low temperatures and just 350 bar pressure. It allows for up to 50 percent more storage than standard 700 bar systems (and, subsequently, a greater driving range). Having CCH2 hydrogen available at a public station allows BMW to further its fuel cell research and development with real-world testing. Read more at Green Car Congress. IKEA will install free EV charging stations at all of its Canadian stores. Each of the 12 stores will offer, initially, two 60-amp chargers available on a first-come-first-served basis. Sun Country Highway will install the chargers by the end of this summer (that's right, you don't have to assemble them yourself). IKEA sees itself as a prime location for EV charging as most of its stores are located near major highways. All of Canada's IKEA stores get their energy from renewable sources. "Electric vehicle charging stations are an important step on IKEA Canada's continuing journey towards sustainability," says IKEA's sustainability manager, Brendan Seale.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.
