This 2014 car is a 50th anniversary homage to classic 1964 Chaser (which I may or may not do and post here at later date).



It's a modern muscle car powered by pure naturally aspirated 5 litre crossplane V8 (man hours: 74.5 , materials: 1746.59 , no Q sliders used anywhere in car btw). 24.4 (US) MPG, 29.3 (UK) MPG.



Chaser II is built on corrosion resistant steel monocoque and covered by aluminium panels to bring down weight. Combination of double wishbone suspension in front and semi trailing arm in rear provides superb weight distribution and driving characteristics.

Nice cars, man! Try to improve that 1.8 in the Shuttle, it certainly is able to make more power than that!

Thanks! I'll take a look at that 1.8 . It's something I made few patches ago and just put it into a car without much thought. From quick look I already noticed that I could easily get low friction pistons for a nice boost in eco, VVL is something to think about too. Though that would push manhours over 30. Decisions, decisions.
EDIT:
I made cheap 106 HP 1.5, with VVL and MPI instead of DI (MH: 31.7 , M: 515.51) 31.78% eco (33.66% on 1.8 after changing pistons and making few small tweaks) and interestingly enough despite 3 more HP and 14 kg less of weight it performs significantly worse, even with 5 gears instead of 4! That 1.8 is better than it looks on paper, main difference I think is that while having less peak HP it has higher torque which peaks much earlier which translates into higher HP in lower ranges. For instance 1.8 achives 60 HP at 2700ish rpm while 1.5 at around 3400rpm. 1.5 is way better when it comes to main stats but I'd like to keep sub 10s 0-100 1.8 gives me though. I'll tinker with it some more to see what else can I get.

New update so a new car. Year 2014, as always no quality sliders used. Goal was to make affordable sports car, nothing too fancy, 300HP engine and light body etc. but after fiddling a bit with engines I realized I can get "supercar" performance for relatively small extra cost because "production units" add less $ than I thought they would.



Roadstar Manta is new high-performance sports car powered by 3,7 litre 32V DOHC crossplane V8 producing 400 HP at 8100 rpm. It's very modern naturally aspirated engine using technologies such as variable valve lift and timing, throttle per cylinder direct fuel injection. It can use regular 95 RON fuel.





Manta's body is build entirely out of aluminium to keep it light and agile. Engine powering rear wheels is mounted behind passenger cockpit. Double wishbone suspension is used both in front and back. It's also equipped with double clutch 6 speed sequential gear box.

Nice ride, dude! I would definitely buy one one those

Thanks to Dragawn I made some significant improvements on Manta. I changed panels from aluminium to even lighter polymer so prestige suffered quite a bit. I guess having car made out of plastic isn't something to be proud of . I also made large number of other tweaks, mainly to wheels and suspension, but even engine received it's share. Results are pretty nice.







It lost 4km/h of V-max but considering it now does 0-100 in 3.1 second and 1/4 mile in 11 seconds flat I think it's good trade of. Even more importantly cornering performance improved a lot. which leads me to improved track times.

Airfield: 80.31
Automation: 136.72

Pretty big gains.

There we go. My attempt at super, super 1000+ HP car using large MR body. I call it Silver Bullet. Yes, I'm not very creative with names. I wanted to hit that magical 400 number for top speed but that would come at cost of acceleration or corner performance or about 5000 extra total cost, 5 km/h just isn't worth it imho but enough of my rambling.

My entry in Der Bayer economic competition. Year 1988, it actually did very well taking second place in total profit and big market share in middle segment. One difference is that I changed look of front grille and headlights to make it look a bit more like 88 car. Stats are absolutely identical.

RM Apollo can be yours for only $30,000 or for free via download below. You wouldn't download a car though, would you?

2000 RM Odysseus is sporty highway cruiser meant for American market. Built on AHS steel monocoque, covered with plain steel panels. Suspension: MacPherson front, fancy multi-link in rear. All wheel drive, manual 5 speed gearbox. Standard interior, entertainment system and safety, however you do get whole check-list of driver assists, Launch Control included.











Engine is aluminium over-square 3 litre naturally aspirated straight six. it's main characteristic is very flat torque line.

that torque profile! Very rare to see one as flat as that!

Helps with tameness a lot, I mean over 80 with manual stick, with automatic it goes to 86.8. Bit of a over kill though so I opted for more sportiness and much better 0-100 and V-max.

Lots of decent cars! With some tweaking here and there I think you can even make them better! Good job and keep up!

Very long post incoming.

So I made pair of large RWD sports cars. Older and newer version of large coupé. Name is quite fitting considering that they were designed in British division of company (and by that I mean that I tried to make them look "British", dunno how well that went so I guess you'll be the judge) and will be pitted against another kind of stallion. So without further ado, let me introduce 1994 and 2005 RM Thoroughbred. Brace for crappy photoshop.



Well then, since we got that out of the way let's dive into 1994 version of the car.



Despite rather large size it actually is fairly light thanks to all-aluminium construction. It also is equipped with pretty sophisticated suspension (Double wishbone / Multi-link), premium interior and entertainment system and most advanced safety measures available. With 0-100km/h time of just 4.6 second, quarter mile time of 13 seconds and first kilometre time of 23.4 second it manages to stay even with the newest 1994 Ferrari F355 (http://en.wikipedia.org/wiki/Ferrari_F355) ! Well that is until cars start to reach their top speeds... F355 with it's 295 km/h v-max definitely has an edge on longer tracks (you got us beat this time Ferrari but just you wait we'll beat you with our next car *shakes fist* ). It managed to do quick time of 1:26.28 on a certain airfield track driven by a certain tamed racing driver.





Car is powered by aluminium 3.5 litre straight 6 with 30 valve head. It's a high-revving, short-stroke unit producing respectable 320 hp at 7000 rpm.




After few upgrades to car and engine in coming years it finally was decided that car needs new, larger, more powerful engine and redesigned chassis to compete with other sports cars, new updated look wouldn't hurt too. Company CEO insisted that after previous defeat it is of utmost importance to at the very least match Ferrari's newest car in top speed, he also started ranting about weight distribution and whatever but we kind of tuned out 5 minutes in.

So here it is, 2005 RM Thoroughbred. Doesn't look quite as aggressive from front but looks can be deceiving.



Again all aluminium construction, thanks to some advances in technology panels don't have to be hand-made any more though. Despite efforts to trim weight compared to first 1994 model it almost gained 200kg of weight! Safety regulations are getting stricter with every year and consumers demand more and more creature comforts in their cars so it couldn't be helped unfortunately. As a side note our design division is already coming up with compact k*tchen (spam filter doesn't seem to like this word) and shower designs that can be fit into a car. Suspension type is again Double wishbone / Multi-link. Interior and safety wise it's same level of package as in 1994. Thoroughbred performance is on whole another level compared to original car. 0-100km/h in 4 seconds flat, quarter mile whole second faster, standing kilometre almost 2 seconds faster and top speed of 315 km/h... which funnily enough does make it fairly even with 2004 Ferrari F430 (http://en.wikipedia.org/wiki/Ferrari_F430). Now this isn't only thing that changed in this car after redesign, V8 was chosen as new engine instead of long inline 6 seen in previous model for particular reason and that is weight distribution (ok there is power too). Our engineers actually managed to achieve perfect 50/50 weight distribution! Which leads me to much improved time on certain airfield track on a certain British motoring show. It did it in 1:22.84.





New heart of a beast. Super light-weight cross-plane V8 which despite having 0.3 litre of displacement more it actually is 23 kilograms lighter than old engine! It is significantly more expensive but it also does produce 105 hp more and is the main instrument in achieving that perfect weight balance.




Wow, I'm not writing posts this long again .
