The Rp1 Roadster has obtained more power and a more optimized construction, appealing an outright exhilarating drive on track and street. When we last appeared in on the Rp1 Roadster at the 2014 Good wood Festival of Speed, Essential was fully committed to making an ultra-lightweight, simple car to maximize the effectiveness of the 280-hp 2. 0-liter Eco Boost engine. The concentrate on low weight hasn’t changed, but the engine specs have. Essential plans to offer the production Rp1 with two mid-mounted options: a 180-hp 1. 0-liter three-cylinder Eco Boost and a 320-hp 2. 0-liter four-cylinder Eco Boost. Individuals engines work with a six-speed sequential gearbox with electro-pneumatic shifting.
If you skim through Elemental’s press materials quickly, you might think there’s a third, 500-hp option, but the 500-hp figure represents the hp-per-tonne ratio, so gowns 1 hp per 2 kg, calculating into a weight of just one, 411-lb (640-kg). Elemental’s website suggests that weight can drop as low as 1, 191 lb (540 kg) with the one particular. 0-liter engine and one particular, 279 lb (580 kg) with the 2.0l.
That low weight helps the 320-hp engine in powering the Rp1 Roadster to 60 mph (96. 5 km/h) in 2. almost 8 seconds and 100 advise (161 km/h) in 6th. 4 seconds, with the 180-hp variant hitting those marks in 3. 2 and 7. 8 mere seconds. Top speeds are outlined at 145 mph (233 km/h) for the one particular. 0-liter engine and one hundred sixty five mph (266 km/h) for the two. 0. Most numbers are estimates, and Elemental remains to be completing screening.
Critical to the Rp1’s feathery light build is the 143-lb (65-kg) CarbonAl tub chassis, which has been improved over the prototype version. The creation Rp1 maintains the recently discussed give attention to driver flexibleness. The suspension can be adjusted with basic tools, or even by hands, letting the driver adjust things perfectly for the specific ride ahead. The Rp1 rides on front side and rear dual wishbones.
