Maserati Quattroporte  (1)

More details have been unveiled about the new sixth-generation Maserati Quattroporte, along with a huge set of hi-res images to accompany the initial five they released earlier this year.

The biggest surprise – the transition to turbo power. The new Quattroporte will be available with two twin-turbocharged direct injection engines – a 3.0 litre twin-turbo V6 and a 3.8 litre twin-turbo V8. The top of the line 3.8 litre motor does 530 hp at 6,800 rpm and 650 Nm of torque from 2,000-4,000 rpm. This can be overboosted to 710 Nm of torque from 2,250-3,500 rpm, which propels the V8-powered Quattroporte up to 100 km/h in just 4.7 seconds.

The new V8’s architecture retains the over-square, free-revving nature of the outgoing V8, with a bore of 86.5 mm and a stroke length of 80.8 mm, and it has a slightly lower compression ratio of 9.5:1. It uses high-tumble cylinder heads with four cam phasers, (double the number of the naturally-aspirated V8).

With hydraulically-adjusted roller finger followers and two continuous cam phasers for each cylinder head, it can advance or retard the inlet and exhaust valve timing independently in real time and it also reduces friction losses compared to old valvetrain systems.

The V6-powered option produces 410 hp and 550 Nm. The engine shares the V8’s bore and combustion chamber design, the same valves control technology (i.e. roller finger followers and four cam phasers), the same twin-turbocharging approach with twin scroll turbos and direct injection-ignition system. The engine auxiliaries are identical (alternator, starter motor and power steering pump) or very similar (variable displacement oil pump).

Both engines are mated to a ZF AT8-HP70 eight-speed automatic transmission, driving the rear wheels. The V6 motor has the option for all-wheel drive. Equipping all-wheel drive reduces 0-100 km/h time for the V6 from 5.1 seconds to 4.9 seconds, thanks to increased traction. The quattroporte has a mechanical LSD, offering 35% lockup under power and 45% under release.

Cabin luxuries include Maserati Touch Control screen, adjustable pedals (left hand- drive only), reverse camera and the optional 15-speaker Bowers & Wilkins audio system, as well as WLAN-based WiFi and compatibility with most modern mobile phone systems.
