Since Summer is almost here, the trends are bound to change. That includes the trends in test drives too. The guys from Car and Driver Magazine took the hottest convertibles out for a drive to let you know which is best.
Their comparison included the Mercedes-Benz SL63 AMG, Porsche 911 Carrera S Convertible, Jaguar XKR-S Convertible and, of course, the F12 BMW M6. Almost all of these cars are powered by V8 engines, all of them had to be as close to the $130,000 (€100.000) price tag as possible and fitted with an automatic gearbox.

Unfortunately, the Porsche was way off. The officials couldn't provide the testers a car with an automatic gearbox (PDK) and sent over a 7-speed manual. Furthermore, the 911 had the smallest engine, with the least amount of power.

The M6 had no problem here. Even though it is the heaviest, widest, longest and tallest of the round-up, it's also the most powerful (not by much though). Its S63 4.4-liter biturbo engine has 560 HP (10 HP more than the Jag, 3 more than the Merc and 160 more than the Porsche) and 680 Nm (501 lb-ft) of torque.

The SL has more torque than the M6 but that's not surprise, as the Merc has a 1.1-liter advantage over the smaller BMW unit. It's peak level of torque is 900 Nm (664 lb-ft) which is absolutely impressive.

The Bimmer was also the cheapest one of the comparison, even though it came with a lot of expensive optional features. With a price tag of $132,145, it was $4,000 cheaper than the Porsche, $6,000 cheaper than the Jag and nearly $40.000 cheaper than the Mercedes.

The interior is comfortable and feels premium inside the M6 and you also get something that resembles 2 back seats (they might be used by children or young adults). The Jaguar interior is old and out of touch with present day. It feels like nothing's changed in the last 10 years, and most of us know how much new technology has been discovered, especially in the automotive field. For such a price tag, the Jag feels seriously un-cool.

Unfortunately, the BMW loses the big race to the Porsche 911 Carrera S Cabrio. The boxer engine wins more points for fuel economy because it's not as powerful and the lighter chassis and direct steering of the 911 contribute hugely. But on balance, we still see the M6 as a sort of winner because it's the second cheapest car tested at $132,000, cheaper even than the underpowered Porsche fitted with a simple manual gearbox.
