“The Hybrid Hurricane”

As Ferrari's first production plug-in hybrid, the Spider is the pinnacle of modern supercar engineering, combining 986 horsepower with the sensory thrill of open-top motoring. The SF90 Spider demonstrates how electrification can amplify rather than compromise the Ferrari experience, creating the most powerful non-limited convertible in the world.

The revolutionary hybrid powertrain combines a twin-turbo 4.0-litre V8 engine with three electric motors, delivering acceleration that defies belief. Ferrari claims a 0-62mph time of 2.5 seconds, but independent testing has recorded an even quicker time in just 2.0 seconds, making this one of the fastest-accelerating production vehicles ever created.

What sets the Ferrari SF90 Spider apart is its intelligent power management system, offering four distinct driving modes. In eDrive mode, the car can travel up to 15 miles on pure electric power, while the desirable “Qualify” mode unleashes the full 986hp fury for maximum performance. The retractable hardtop maintains structural rigidity while allowing you to experience the full drama of Ferrari's most advanced powertrain without barriers.

6. Aston Martin DB12 Volante

“The Icon”

In the battle for the ultimate convertible grand tourer, Aston Martin proudly presents its DB12 Volante model - a beautifully proportioned "Super Tourer" that reminds you why this is James Bond's brand of choice. As a flagship convertible, this road-roarer is the pinnacle of Aston Martin's current lineup, wrapped in an elegant package that epitomises British luxury and performance.

Housing a hand-built 671hp 4.0-litre twin-turbo V8 up front, the DB12 Volante delivers genuine supercar performance with a 0-62mph time of just 3.4 seconds and a top speed of 202mph. Lowering the roof might be the preferable option, however, as you're going to want to hear the Aston's magnificent V8 releasing its sweet melody. We’ve heard it described as sounding "like Rod Stewart with laryngitis - deep and gravelly, but still properly tuneful." We think this sums it up nicely!

Combining traditional British craftsmanship with cutting-edge technology, the convertible roof can be lowered in just 14 seconds at speeds up to 31mph, and when it's down, you're remarkably well protected from wind buffeting even at motorway speeds. The sophisticated interior features soft hand-stitched leather covering most surfaces, with stainless steel details replacing the plastic found in lesser rivals.

At its heart lies the legendary 4.0-litre naturally aspirated flat-six engine borrowed directly from the 911 GT3 model, producing 493hp and 331 lb-ft of torque. This magnificent powertrain enables the Spyder RS to accelerate from 0-60mph in just 2.8 seconds, while the top speed of 191mph with the roof down ensures that this Porsche delivers genuine hypercar performance. 

What makes the Spyder RS truly special is its uncompromising focus on the driving experience. The manual soft top is a deliberate weight-saving measure, while the interior has been stripped of non-essential luxuries in favour of pure functionality. With the roof down, you're treated to one of the most intoxicating engine notes in the automotive world – a naturally aspirated flat-six that revs to 9,000rpm without the assistance of turbochargers or electric motors.

Did You Know?

The Porsche 718 Spyder RS features the same naturally aspirated 4.0-litre flat-six engine as the legendary 911 GT3 model, making it a true collector's item as 2025 marks the final year of 718 production before Porsche transitions to all-electric powertrains for their compact sports cars.
