Your logic is flawed. Start-stop technology has been widely used and accepted in European luxury sedans - in Europe - since 2011. It is and has been proven to save fuel dramatically, and the increased power as you are quoting above is negligible at best. The technology, already proven in Europe—and of course, in a different form, in many hybrid models—has reached a sort of tipping point, such that it isn’t just being cautiously introduced by a single automaker; nearly all of the new diesels offered by luxury brands will soon have stop-start, and every single diesel introduced in the fall in fall of 2013 in a luxury vehicle has it. That includes the BMW 328d sport sedan, the Mercedes-Benz E250 Bluetec, and the new TDI versions of the Audi A6 and A8 sedans, A7 hatchback, and Q5 crossover.
