Porsche 928
The Porsche 928 is a sports-GT car that was sold by Porsche AG of Germany from 1978 to 1995. Originally intended to replace the company's iconic 911, the 928 combined the power, poise, and handling of a sports car with the refinement, comfort, and equipment of a luxury sedan to create what some Porsche executives thought would be a vehicle with wider appeal than the compact, quirky and sometimes difficult 911.
Since its inception in 1949, Porsche has manufactured only six front-engined models, four of which were coupes, including the 928. The car has the distinction of being the company's only coupe powered by a front-mounted V8 engine, and the company's first mass-produced V8 powered model.

A hotter Porsche 928 went on sale in Europe in 1980, but America didn't get the more potent 234-bhp engine until 1982, along with a new four-speed automatic transmission. The Porsche 928 proved its mettle by reaching a top speed of 172 mph in Utah in 1986, making it the fastest production car on the road.

Porsche 968
The

Porsche

968 was powered by an updated version of the 944's straight-4 engine, now displacing 3.0 L with 104 mm bore, 88 mm stroke and producing 240 PS (236 hp/177 kW). Changes to the 968's powertrain also included the addition of Porsche's then-new VarioCam variable valve timing system, newly optimized induction and exhaust systems, a dual-mass flywheel, and updated engine management electronics among other more minor revisions. The 968's engine was the second-largest 4-cylinder ever offered in a production car up to that time. A new 6-speed manual transmission replaced the 944's old 5-speed, and Porsche's dual-mode Tiptronic automatic became an available option.

It is the second plug-in hybrid car from Porsche, after the 2014 Porsche Panamera SE-Hybrid.

Porsche 930 Turbo
The

Porsche

930 proved very fast but also very demanding, prone by its short wheelbase and rear engine layout to oversteer and plagued by significant turbo-lag.


Porsche made its first and most significant upgrades to the 930 for 1978, enlarging the engine to 3.3 litres and adding an air-to-air intercooler. By cooling the pressurized air charge, the intercooler helped increase power output to 300 hp (DIN); the rear 'whale tail' spoiler was re-profiled and raised slightly to make room for the intercooler. Porsche also upgraded the brakes to units similar to those used on the 917 racecar.
