Extensive details about the 2015 Volkswagen Passat have emerged through a leaked presentation, prior to next month's confirmed official introduction.

First up, the diesel engine lineup will include a 1.6-liter TDI with 120 PS (88 kW) along with three 2.0-liter TDIs delivering 150 PS (110 kW), 190 PS (140 kW) and 240 PS (176 kW).

On the gasoline side, we find two 1.4 TSIs with 125 PS (92 kW) and 150 PS (110 kW), with the latter featuring Active Cylinder Technology (ACT). There's also a 1.8 TSI with 180 PS (132 kW) and two 2.0-liter TSIs with 220 PS (162 kW) and 280 PS (206 kW).

All these engines meet Euro 6 emissions standards and Volkswagen is also planning a plug-in hybrid version with an electric motor and a 9.9 kWh battery pack granting a maximum electric range of around 31 miles (50 km) and a combined range of 600 miles (966 km). On this version, the charging socket will be positioned in the badge on the front grille.

The all-new Passat is going to be 4767mm long and will be up to 85 kg (188 lbs) lighter than its predecessor. It will come as standard with full LED taillights and will be optionally available with LED headlights with a Dynamic Light Assist system. Inside the cabin it will boast Audi TT's 12.3-inch digital instrument cluster with a resolution of 1440 x 540 pixels and will be offered with a head-up display system and park assist. There's also a 360-degree camera and a trailer assistant system.

Many of these details were already announced by Volkswagen at the end of May when they said the 2015 Passat is going to pack a variety of safety and assistance systems such as City Emergency Braking, Traffic Jam Assist, Side Assist with Rear Traffic Alert, Front Assist and others.

The 2015 Volkswagen Passat will be unveiled online next month and it's set to go on sale before the end of the year, following a public debut in October at the Paris Motor Show.
