Porshe New 911 GT3 on the road



The Porsche 911 GT3 is based on the current 911 Carrera. Not surprisingly, this track denizen is built to keep things simple and the weight down. The interior is a bit spartan, but refreshingly functional. The 911 GT3 has a new all-aluminum chassis with a lightweight yet stiff body, with independent front and rear sections that can be adjusted by height, toe and camber.

Under the bonnet, the Porsche engineers went to town. The 911 GT3 has a naturally-aspirated, 3.8-liter, 6-cylinder boxer engine, which is derived from the 911 Carrera S (though they have few parts in common). It packs 475 bhp (350 kW) at 8,250 rpm and maxes out at 9,000 rpm. Most of the components were adapted or designed for the GT3, including the titanium connecting rods and forged pistons, the crankshaft, and the valve gear. With the lightweight chassis and body, this gives a power-to-weight ratio of 3.0 kg/hp.

Among the ohe GT3 also sees the implementation of the fuel-saving electrically assisted power steering. How that will affect the steering feel is yet to be seen, but thankfully the same system fitted to standard 911s have been rather decent to say the least.Another Porsche-first is the use of active rear-wheel steering. This turns the two rear wheels into or away from the corner according to speed, aiding stability and agilityther new driving dynamics features are larger 20-inch wheels, electronically-controlled, fully variable rear differential lock and the now-standard dynamic engine mounts.

Proton Inspira 2.0 Executive

Proton has introduced an Executive version of its 2.0 litre CVT Inspira – the variant replaces the 1.8 CVT Executive in the model lineup, slotting in between the 2.0 CVT Premium and 1.8 MT Executive. Most of the kit found on the 2.0 Premium is on the 2.0 Executive – from the steering wheel audio switches and paddle shifters to the auto light and rain sensors, it’s all here. What’s different, based on the feature specifications list, is that the Executive’s seats and door trim finishing is in fabric (as opposed to the Premium’s leather fitment), the wipers don’t feature automatic speed adjustment and the bodykit has been omitted. Fresh to the car is a new 16-inch wheel design. As for exterior colours, there’s no Plum Red for this one, with the Premium’s shade being replaced by Elegant Brown; otherwise, Tranquility Black, Genetic Silver and Solid White are shared by both variants. The revisions make for a significant drop in the asking price over the Premium variant though – the 2....
