This is a car.


It does things that cars do.


#44

Yeah, but is it award-winning?


#45

That roof scoop!


#46

Maybe it is a periscope :sweat_smile:

I don’t see a hitch anywhere, but I am positive it can be attached to the rear wing. :smiley:

And now, on a more relevant note, here is a sneak peak at the new-for-the-1980s IMP sedan offerings.

But first, lets talk about politics.

Shortly after the capitulation of the Third Reich Germany had been totally demilitarised, with the Wehrmacht being dissolved. For the following nine years Germany was without an army. That all changed when the cold war began to heat up, with the freshly founded Federal Republic of Germany being in the unique position of having a Warsaw-pact aligned sister state in the German Democratic Republic. The FDR eventually joined the NATO in 1955 and later that year the Bundeswehr was founded. Naturally an army needs vehicles and thus IMP competed to get the contract for the standard issue 1/4 ton off-roader, however they lost to the DKW Munga. A few years down the line, IMP once again proposed a vehicle for the BW, this time a 1/2 ton off-road personnel carrier slotted between the Munga and the Daimler-Benz Unimog derived from a 1942 prototype designed to deal with the harsh environments of the Eastern Front. The basic chassis design was carried over, but significantly modified with a 4WD system similar to the Willys Jeep, simplified suspension and fitted with a detuned version of IMPs then-new C-series Inline 6. After a number of tests by the BW the vehicle was once again sent back to IMP to be further improved according to their suggestions. The “Leichter Geländelastkraftwagen Typ 115” or L115G in short was finalized in 1961, with the Bundeswehr placing an order for 1500 trucks that were put in service in late 1962.


The original specification utilized a modern 2.3L cross-flow Inline 6 from the IMP passenger engine line not unlike the Unimog 404S, that was detuned to produce more torque at low rpm and equipped with a single two-barrel carburettor and 7.5:1 CR produced 90hp and 177Nm. With a fully synchronized four speed transmission and a heavy-duty cooling system it was capable of operating at highway speeds for extended periods of time.
Once the original contract was fulfilled, Bundeswehr officials requested IMP develop a version with a higher, one-ton payload as well as a diesel engine option. The 2.3L engine was deemed insufficient for the task, thus IMP sourced the engines from the smallest Monolith truck, a 4.5L aluminium V12 petrol engine and a 4.1L two-stroke Diesel. Both of those engines had very high power to weight ratios with the V12 being just 35kg heavier than the six but developing nearly twice the torque. Those versions were known as the L115/6GB and L115/6GD, and built from 1964 until 1967 with around 2800 units being built.


L115G (1962-1963, 1514 units)
2.3L OHV Inline 6 [IMP C 2300L1], 90bhp, 177Nm, 4MT, 4WD, 1428kg

L115/6GB (1964-1967, 1126 units)
4.5L OHV V12 [IMP BT12-CBW 4500], 145bhp, 348Nm, 4MT, 4WD, 1557kg

L115/6GD (1964-1967, 1619 units)
4.1L uniflow-scavenged two stroke Diesel [IMP 206DWB], 121hp, 381Nm, 4MT, 4WD, 1610kg

Romanov Automobiles would like to clear up any confusion about the emblem used by IMP, which is not an indicator for a collaboration between the two manufacturers, with IMP of course being on the wrong side of the curtain.

Thanks for your attention. Spasibo za vnimanie.


#53

Ich want to know why a sowjet company uses a Reichsadler for zeir emblem.


#54

IИ SOVIET ЯUSSIЛ, EMБLEM USE УOU!


#55

*Bundesadler, if so.

Not every eagle used for a coat of arms is of German origin. Not that Germans invented eagles. :smiley:


#56

The Reichsadler is still the best, though.

I have nothing to do, have another car.

In the 1960s the Ford Mustang took America by storm with its unbeatable combination of style, affordablility, customization and in sometimes performance, prompting General Motors and Chrysler to make their own pony cars, resulting in the Camaro, Firebird and Challenger. Eventually the Pony car recipe also made its way to Europe, and once again it was Ford who got the ball rolling with the Capri in 1969. Just months after GM fought back with the Opel Manta and Vauxhall Firenza. That much activity in a relatively new segment caught IMPs attention, and thus in late 1971 the Club was born.


Much like the Capri and Manta it was based on a humble family car, but there were a few differences in the execution. IMP did not offer any base engines, the smallest engine on offer in the Club was a 1.7L Inline 4 with a healthy 92bhp, with 1.9 and 2.1L engines being optional. Furthermore unlike the somewhat crude competition the Club had a new and sophisticated independent rear suspension. Combined with the usual IMP overbuilding the Club ended up being significantly more expensive than the Capri and Manta, with a starting price of 12,483DM (the Manta 1.2 was nearly 4,000DM cheaper). At least all versions of the Club delivered on their sporting pretenses. Initial reception was good, and in 1972 two new GT models were added. Each of them had its own approach, the GT-S was a lightened, hardcore version that had a more aggressive 2.1L engine with uprated camshafts, valves, a forged rotating assembly and two Weber 45DCOE carburetors good for 165bhp and 204Nm of torque.
The GT-L on the other hand was positioned as more of a compact grand tourer, with a fuel injected all-aluminium Inline 6 that made roughly the same power but slightly more torque and had a much more comfortable interior. It was also the only model optionally available with an automatic transmission.

Sales were strong, if considerably lower than the Capri/Manta, regardless a mild facelift was released in 1974. Apart from a new grille and taillights the main difference was the new engine, an all aluminium inline 4 based on the GT-L’s H-Series Inline 6 and available in 1.6L and 2.0L displacement, both with K-Jetronic fuel injection like their bigger brother.
The GT-L remained unchanged aside from the altered appearance, while the GT-S was replaced with the GT-E, now powered by a fuel injected 2.0L engine, although less powerful. The GT-E was altogether a little more convenient than the hardcore GT-S, for instance it had rear seats and a radio.

Eventually the design began to show its age, and for 1978 a second more substantial facelift that reflected the new IMP design language was applied to the Club. The oval headlights, a distinctive feature of all IMP vehicles since the early 1960s were replaced with modern, angular compound headlights. Unfortunately the GT-E fell victim to ever tightening emissions regulations which the engine requiring leaded premium fuel could not meet. Instead of letting the high performance versions die altogether IMP did what most wouldn’t do and beefed up the GT-E with a 3.0L engine based on the GT-L and wide 235 section tires to form the GT-R.

The GT-R was not only faster than the GT-E with its 180bhp, it also had significantly greater torque reserves at low rpm and had no issues with the tree-hugger unleaded fuel. The 1.6, 2.0 and GT-L remained unchanged until the end of production in 1982.

But wait, there is one more version of the IMP Club.
During the 1970s, Crayford Engineering built 33 convertible conversions of the Club with whatever engine the donor cars came with.


The majority had either the early 1.9L or 2.1L, but there were also four GT-L based conversions as well as two with the rare GT-S engine one of which was lost track of in the early 1990s. Today, Crayford Convertibles are together with the GT-S the most valuable models.

What do you do if you have just built a Supercar prototype thats been held back by 1980s Diesel tech? And what if you just so happen to have a few custom built prototype V12 engines left over from a recent Collaboration with Kraft Haus Technik?

Why not combine the two?

Enter the 1991 IMR RC-039 G-Sport.


As you can see it is almost identical to the 1990 D-Sport, except for a few wings to add downforce at high speeds and some wider wheels. The main difference obviously comes down to the powertrain. In fact it uses the same IMP J33 based V12 engine as the KHT Atlantic and Atlantic GT, it even has twin turbos just like the KHT. However whereas the Atlantic uses a custom KHT Turbo setup, the G-Sport engine benefitted from IMPs comparatively much more vast resources. The engine features hollow prototype camshafts with increased lift and duration compared to standard IMP J-Type cams. The cylinders have been overbored from 88mm to 92mm while keeping the default 90mm stroke, netting a displacement increase of 0.6L for a total displacement of 7179cc. Since the thinner cylinder walls weaken the aluminium engine block, internal bracings have been added to compensate for this. The engine uses 8,2:1 compression forged steel pistons and two IHI turbochargers with a 60,5mm Turbine and 60,5mm Compressor. Using a relatively low boost threshhold of just 0,6bar the engine produces maximum boost at 2800rpm. Fuel mixture is comparatively lean coupled with advanced ignition timing for reasonable volumetric efficiency. Despite this it is capable of producing 720hp and 890Nm on 95 octane premium fuel.

Apart from a stronger transaxle and retuned suspension the RC-039 itself hasn’t been altered. It retains the comfort oriented interior designed primarily for high-speed long distance traveling. It now accelerates from 0-62mph in 3.3 seconds and will reach a top speed of 362,7kph. If it wasn’t just a prototype it’d be king of the Autobahn, which is why it’s been nicknamed “Autobahn” by a number of people in honour of a lost prototype built by IMP in the late 1930s.


1991 IMR RC-039 G-Sport “Autobahn” Concept:
IMP GJ72T Custom Twin Turbo V12, 92x90mm, 7179cc, DOHC 48V, 718hp @ 6800rpm, 893Nm @ 4500rpm, 348kg (wet)
5-Speed manual transmission, MR Layout
1585kg curb weight
0-100kph: 3.3s
Top Speed: 362,7kph (226,7mph)
Fuel consumption: 15,6L/100km
Projected price: 340.000DM

'doh!

Well… with this, Jag XJ220 and the F1 on the market in the early 90’s, I think I’ll have to push the car a bit further…


#60

It’s not on the market. All RC models up to this point are prototypes.

Although, that might be subject to change at some point in the 1990s (hint hint).

Yet another 1990s car:


In 1991 IMP entered the highly lucrative market for expensive luxury GT cars with the almost all-new R37 Roadfortress, a car designed to rule the Highways of the world. Based on the same platform as the contemporary IMP Opera sedan, it did away with the sedan bodywork, the rear seats, and some of the wheelbase. It was never a secret that this car was specifically designed for those wealthy people who enjoy long distance driving, or maybe had to because of their work. As a result the main development goals were comfort, high-speed stability and economy. The lack of rear seats highly benefitted the trunk space, with over 670L of storage space available. To ensure that stability was not affected when traveling with 800lbs of luggage and two people on board the R37 was fitted with self-leveling rear suspension as standard. Also standard were ergonomically certified heated seats and a high-end audio system.

At launch in 1991, only one engine option was available, the proven 3.8L SOHC Inline 6 found in the Opera and some Monolith trucks, slightly reworked for this application to give 295hp instead of the usual 258hp. Peak torque remained 370Nm @ 3800rpm. It could be ordered with a 5-speed M550 manual or the A440E 4-speed automatic.
By 1992, the inline 6 was complemented by a destroked version of IMPs VT60E V8, with 5.8L and 400hp. This model featured air suspension and a standard A465E automatic transmission.
More interesting however is the DIESEL ( you know me :slight_smile: ) version, using the same 4.0L Inline six Turbodiesel as the crowd-favourite RC-039 D-Sport supercar, with slightly less boost to allow better fuel economy and longetivity. This made it less powerful with 240hp @ 4000rpm and 450Nm of torque @ 1800rpm. Nevertheless this made it nothing less than the fastest and most powerful diesel powered production car for many years to come. It too could be ordered with the M550 manual or the A465E automatic. Economy was damn tight as well, being capable of 36mpg combined when fitted with the manual transmission. Remember that is the combined figure, its highway mpg has been rated at 45mpg. Thanks to the 100 Liter fuel tank the diesel powered R37 could theoretically do over 1100 miles between refills. Nice.

Of course being an IMP product the Roadfortress is also as reliable as death, leading to them being nicknamed the “Landcruiser of sports cars”. The V8 and Diesel in particular are well known to regularly exceed 500.000 miles without rebuilds, one Diesel did in fact manage to reach the magic million without a rebuild, thanks to comprehensive maintenance and almost exclusive highway use.
However no car is perfect, and the air suspension units on the V8 can in fact develop leaks after a few years of use, which can cost over $4.000 to fix, which is why IMP also offers retrograde kits to replace the air suspension with conventional coil springs and shock absorbers.

Obviously this sounds like the best car ever built, but beware that it is
more expensive to buy and maintain than comparabe vehicles such as the BMW 850ci. Thankfully it doesn’t break down very often.


R37 Roadfortress B38:
3.8L SOHC Inline 6 [IMP H38GIII], 295hp, 370Nm, 1540kg, 11.2L/100km (21mpg) (1991-1998)

R37 Roadfortress B58:
5.8L SOHC V8 [IMP VT58G], 399hp, 556Nm, 1650kg, 14.3L/100km (17mpg) (1992-1998)

R37 Roadfortress Type D:
4.0L SOHC Inline 6 Turbodiesel [IMP D640T-V240], 239hp, 448Nm, 1584kg, 6.5L/100km (36mpg) (1992-1998)
