My thinking exactly.
Or maybe they are on the news letter :)
Of course this is only one milli second not fast enough for a rotary.
Down from the 2 milli seconds on a stock RX8 coil.

BorgWarner produces multi-spark ignition coils in Germany
BorgWarner is producing multi-spark ignition coils at its plant in
Muggendorf, Germany, for Daimler’s six- and eight-cylinder engines. With
displacements between 3.5 and 5.5 liters, and power ratings ranging from
252 to 556ps (185-410kW), these powerful engines are available in the
Mercedes-Benz C-, E- and S-Classes. Specially designed for gasoline
direct-injection (GDI) engines running stratified combustion,
BorgWarner’s compact multi-spark ignition coil technology enlarges the
ignition zone for more controlled and optimized combustion, improved
fuel economy and reduced emissions.
“BorgWarner’s multi-spark ignition technology extends spark duration and
provides the high ignition voltage needed to optimize engine performance
for today’s turbocharged direct-injection gasoline engines,” says Brady
Ericson, president and general manager, BorgWarner Emissions Systems.
“By increasing frequency and variability, BorgWarner’s advanced ignition
technology allows automakers to take advantage of high exhaust gas
recirculation rates, turbocharging and stratified charge operation to
improve fuel economy and emissions.”
Based on a conventional 14V coil, BorgWarner’s multi-spark ignition coil
features a bi-directional interface with an electronic control unit to
precisely trigger multiple discharges and recharges within one
millisecond to produce spark energy multiple times at short intervals.
Enlarging the ignition zone and generating multiple sparks extends the
spark duration considerably to deliver optimal combustion, improved fuel
economy, lower emissions, and it prevents misfires. In addition,
BorgWarner’s ignition technology helps reduce emissions during
cold-starts and improves engine running under nearly any operating
condition.
