If the four-seat convertible supercar from Holland isn't enough of a thrill for you, then hopefully its racing counterpart will meet your lofty expectations. Both the GTS and GTR were recently on show at the Top Marques show in Monaco. The road-going Roadyacht GTS uses a high-performance 7.0-liter LS7 V8 engine from the Corvette Z06, producing 601hp and 553lb-ft of torque. A top speed of 205mph and 0-60mph sprint time of 3.4 seconds has been reported, but its most interesting feature is the RTMP roof.

The Retractable Telescopic Multi-Panel hard top is made up of four glass panels with carbon-fiber reinforcement sills that slide down to the boot via an extendable telescopic center arm. Built on the same platform as the GTS, the Savage Rivale GTR is good for around 700-800hp and 575lb-ft of torque. Top speed is measured at 224 mph and sprints from 0-62 mph in 2.8 seconds. Only 69 will be built, with a Chrome Moly hand-constructed chassis, scissor doors and xenon lights. A 6.2-liter V8 gasoline engine is mated to a 6-speed manual transmission, while a front-mounted turbocharger feeds the mid-mounted engine with power driving the rear wheels.

The GTR also boasts a straight-pipe exhaust, ceramic Brembo brake system, and fully adjustable coilovers sitting on double wishbone a-arms. Inside, a custom carbon-fiber race spec interior houses Recaro race seats with six-point belts. At 141,250 Euros, this will be out of most people's range but that's a decent price for a custom-built race car. We look forward to the final specs being released, in the meantime enjoy these quality images taken in Monte Carlo.
