Bruno Senna, the late Ayrton Senna's nephew, joins the programme as a special guest presenter. Bruno is on the verge of becoming an F1 driver and was perfectly placed to tell us which four-wheel-drive supercar is best - the Nissan GT-R or the Porsche 911 Turbo.
Porsche 911 Turbo
The Turbo version of the 911 series featured the same 3.6 L twin-turbocharged engine as the 996 Turbo, but this time it developed 480 PS (353 kW/473bhp) and 620 N·m (460 ft·lbff) of torque.0 to 100 km/h (62 mph) in 3.7 seconds ; Top speed of 310 km/h (193 mph).
Nissan GT-R
The Nissan GT-R is powered by the VR38DETT engine, a 3.8 L (230 cu in) DOHC V6. Two parallel Ishikawajima-Harima Heavy Industries (IHI) turbochargers provide forced induction. Production vehicles produce 480 bhp (360 kW) at 6,400 rpm and 434 ft·lbf (588 N·m) at 3,200-5,200 rpm. 0-60 mph (97 km/h) times as low as 3.2 seconds ; Top speed of 195 mph (314 km/h).
