BMW matriarch Johanna Quandt dies at 89

Johanna Quandt, matriarch of the family that owns the largest stake in BMW, has died at age 89. One of the world's richest women, Quandt ranked in her own right as the eighth wealthiest individual in Germany, and one of the 100 wealthiest billionaires in the world. Johanna Maria Bruhn was born in June 1926, the daughter of art historians in Berlin. She trained in medical technology before the outbreak of World War II, and after the war worked as a banker's secretary in Cologne. She started working for Herbert Quandt in Bad Homburg, near Frankfurt, in the mid-1950s, and eventually became his personal assistant. They married in 1960, shortly after increasing the family's stake in BMW to 50 percent in order to stave off a takeover attempt by Daimler-Benz. The Quandt family's fortune was controversially amassed during the war. Herbert's father, Gunther Quandt, was a top Nazi-era industrialist named by Adolf Hitler as a Wehrwirtschaftsfuhrer – Leader of the Armament Economy. After Herbert's mother Antonie died, Gunther remarried to Magda, a much younger woman. Following their subsequent divorce, Magda married Nazi master propagandist Joseph Goebbels (with Hitler as best man), and together raised Herbert's half-brother Harald. A recent documentary found that the AFA, the company that the Quandts controlled during WWII, used slave labor provided by the Nazi regime to manufacture battery and munitions for the German war effort. Due to the subhuman living and working conditions, AFA lost approximately 80 forced laborers each month. Despite earlier denial of any wartime wrongdoing, the documentary and ensuing public attention prompted the Quandts to open their books to another investigation that confirmed their wartime activities. The Quandts would later use the capital they amassed to buy BMW, of which they still hold 46.7 percent – the remaining 53.3 percent traded publicly. Following Herbert's death in 1982, Johanna took over 16.7 percent ownership in the company, with their son Stefan Quandt acquiring 17.4 percent and their daughter Susanne Klatten assuming 12.6 percent ownership. Stefan and Susanne, both members of BMW's supervisory board since 1997, are expected to inherit their mother's shares following her passing. Johanna's personal fortune was estimated at nearly $14 billion. Though reclusive from media and public attention, she gave generously to charitable foundations that supported such causes as medical research and business journalism.

BMW 4 Series Convertible basks in the sun

The BMW 4 Series Convertible will show its non-camouflaged face sometime later this year, but our spies recently caught this nearly naked prototype out getting some sun. As you'll recall, the droptop 4 Series replaces the 3 Series Convertible in the BMW range, and if our recent stint behind the wheel of the new 435i Coupe is anything to go on, this topless 4er should be quite a fun runabout for sun-drenched motoring.
To no one's surprise, the 4 Series Convertible shares all of its design with the 4 Series coupe, save, of course, the obvious roofectomy. Beyond that, the topless 2+2 will use the same engines and transmissions as the coupe, meaning it should arrive in the US in both 428i and 435i guises, powered by a 2.0-liter turbocharged inline-four and 3.0-liter turbocharged inline-six, respectively. Both six-speed manual and eight-speed automatic transmissions will be available.
The car spied this time around has the full M Sport visual treatment, with the revised (and better-looking) front fascia, larger 19-inch wheels, and attractive Melbourne Red paint. Interestingly, it appears this prototype has the standard xenon headlamp setup, rather than the full-LED option that's also available.

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.
