The Maserati GranSport is a derivative of the Maserati Coupé produced since late 2001 with 4.2-liter Ferrari V8 engine. He was presented in the fall of 2004 as GranSport (Coupe) at the Geneva Motor Show. Later followed the open Spyder. The name Gran Sport takes up a designation of a classic Maserati model; as Gran Sport 1956 and 1957 special coupe of the series A6G / 54 were sold. [2] [3]
The coupe-based GranSport gets subtle retouching on the body, minor technical changes to the engine and circuit. Maserati shortened the reaction time of his Cambiocorsa circuit ("racing circuit" [4] ). The new front and rear aprons together with the small tear-off edge on the boot lid ensure more downforce. In addition, the body of the GranSport was lowered by ten millimeters and the suspension tuned firmer. All together improves driving performance and reduces lift and drag (c w = 0.33). With the GranSport Coupe Maserati competed against the Porsche 996 GT3 and Ferrari 360 Challenge Stradale .
The production figures of the GranSport Coupe are:
2005: 813 units
2006: 1,156
2007: 183
A total of 2,152 GranSport coupes were built.
The Maserati GranSport is a sportier version of the Coupé that was first unveiled at the March 2004 Geneva Motor Show.[45] It featured improved aerodynamics, retuned suspension, engine and transmission, and a sportier interior. An open-top GranSport Spyder with similar modifications was introduced a year later, at the September 2005 Frankfurt Motor Show.[46]
It is powered by the same 4,244 cc, dry sump, 90° V8 engine used on the standard Coupé and Spyder. However, the engine is rated at 400 PS (294 kW; 395 hp) at 7,000 rpm due primarily to a different exhaust system and improvements on the intake manifolds and valve seats.[47] Only the six-speed Cambiocorsa paddle shift transmission was offered, and was recalibrated for quicker shifts. The exhaust, equipped with bypass valves, was also specially tuned to "growl" on start-up and full throttle.[48] The GranSport used the Skyhook active suspension, with a 10 mm (0.4 in) lower ride height. Other than height, the exterior dimensions and curb weight were unchanged from the Cambiocorsa Coupé and Spyder.[49] The GranSport had a claimed top speed of 290 km/h (180 mph), and a 0 to 100 km/h (0 to 62 mph) acceleration time of 4.85 seconds.[50]
The higher top speed was possible due to a taller sixth gear ratio and more aerodynamic body cladding. New bumpers, side skirts, rear lip spoiler and underbody panels lowered the drag coefficient by 0.02 to 0.33[50] and simultaneously reduced lift.[51] Chrome mesh grilles to the front and rear bumpers, and "Trofeo"-design 19-inch wheels with trident-shaped spokes were other distinguishing exterior features.
Inside, the GranSport was fitted with wide, highly contoured sport seats, which required a slimmer centre console (constructed in carbon fibre) and elastic door pockets. Carbon fibre was also used to for the dashboard trim and on the new thick-rimmed steering wheel. On the coupé, the upholstery materials were leather and technical cloth (in black, Nickel Gray or Metal Blue) on the seat centres, backs and dashboard fascia;[50] the Spyder had an all-leather interior. Seven paint colours were available: solid Giallo Granturismo and Rosso Mondiale, metallic Nero Carbonio, Blu Mediterraneo, Grigio Alfieri and Grigio Touring, and special triple-layer white Bianco Fuji.

Great job! In my experience with many older cars, in addition to spark plugs, replacing vacuum hoses is another inexpensive and usually necessary preventative maintenance. Even a minor leak affects performance. Cheers
Enjoying the Panda's Garage segments, keep it up!
Nice one mate ... basic straightforward advice with no frills ... ace !
Niiice tips!
cam variators can cause rough sound for 2-5 seconds after cold start.
Have you had any problems with ticking noises from the engine
Fantastic video - I have a red 2006 Maserati Gransport. Have you thought about adding Larini decats and Tubi or Larini exhaust? The decats gets rid of the squashed piping below and adds more power and sound. Did you lower the car?
Kindly,
Stephen
I haven't done anything in mods particularly. I try to keep things as stock as possible.
The secondary cats on these cars are prone to failure. Also be sure to look at the heater core as this part fails as well...if it does the coolant can leak behind the dash frying your electronics. Do you plan to post more videos?
Nice - I, too, have a red '06 GranSport. How do you tell if the cats are bad? I think everything on my car is running pretty well, but I've not checked out the exhaust yet.
Thanks I own one
Do a smoke test and see if there are any vacuum leaks
Hello ,i might buy 2003 with 73000 km Maserati 4200 390 ps ...i am just afraid of the maintenance if it is very expensive and if it is really reliable or not ? I would really appreciate if you or any of the owners will give me an advice and the problems that you faced in this car .Thank you
I have bought one, very reliable and parts are available, these cars are absolute bargain
Put Rice in the intake
Help me bro I have a Spyder I don’t want to mess up my engine
Hey u know a lot about these cars can we work together and you help me with my vehicle
Peter, how has your ownership with the Maserati been? Is it hard to drive with gearbox and transmission etc. Have you had any main issues with transmission since owning? I am looking to get one myself :)
I was scared of the transmission but it’s been solid and fun to drive once you get the hang of it.
@@petervonpanda Wow that's kool to know. Seems like such a great car if the transmission behaves itself and we respect the way it functions. Any tips on how to preserve the transmission from a driving behaviour point of view? Thanks again :)
@@JDGDare2Dream get a manual it's the solution
@@RezaAlasadi nah manual is slow and clunky, f1 gearbox is for sure the way to go.
Most car makers put covers over engines. At maserati they don't they put covers over everything else
That's very normal behavior, especially on a cold start.
Ron Cosby my 4200 runs rough at cold start for about 10 seconds or so if it sits for a few days and that’s even after the spark plug change
Mine is a bit lumpy at start up as well but it’s probably overdue for some new plugs as well. Have you found it to drive a bit better after the plugs were replaced?
Nah. Should not be the case. If the coils are fine (which is often a cause for this behavior) and now vacuum leaks (9 out of 10 causing these kind of issues) then it should run perfectly smooth. Cold or warm doesn't matter
Ron Cosby
Yeah those italian cars take Some time to build up the oil pressure
Hello help me please I own one Spyder help bro
Hey
Yo
Hey help
