Overview
The Lagonda DP115 is part of LMC26 Grid1, the mid-1950s grid. It uses a Lagonda DP100 V12 with a displacement of 4,487 cm³ (4.49 L). Available entries are No. 14 David Brown Corporation / Reg Parnell and No. 12 Old Drivers Spirit / ODS Guest.
History
The Lagonda DP115 raced in 1954, with chassis DP115/1 taking fifth overall on its debut at Silverstone. Eric Thompson and Dennis Poore shared that car at Le Mans a month later, but an early accident ended its race. Ultimatecarpage
LMC specifications
Specifications for the current LMC configuration.
| Specification | Value |
|---|---|
| Mass (kg) | 1,072 kg, excluding fuel |
| Engine and displacement | Lagonda DP100 V12, 4,487 cm³ (4.49 L) |
| Transmission and number of gears | Rear-wheel drive; 5 forward gears; ratios 3.120:1 / 2.070:1 / 1.460:1 / 1.200:1 / 1.000:1 |
| Fuel capacity (l) | 189 L maximum; 95 L default |
| Brakes | Drum brakes on all four wheels; default balance 56% front / 44% rear |
| Tyres | Default garage pressures: 180 kPa (1.80 bar) front and rear |
Driving advice
The car has rear-wheel drive and a default weight distribution of 54.5% front / 45.5% rear. The rear anti-roll bar is disconnected at the default setting. Differential settings and individual gear ratios are fixed; the final drive can be changed in the garage.
There is no active engine rev limiter. Downshifts can drive the engine beyond its useful speed range. Brake balance is adjustable in the garage, but not while driving.
Braking
| Technology at Le Mans in 1954 | Representation in the current LMC physics |
|---|---|
| Drum brakes on all four wheels | Limited cooling, with slower cooling at the rear than at the front. The nominal full-effectiveness temperature range is 290–555 °C on both axles; heat accumulation during repeated braking can cause fade. |
Fade means a loss of braking effectiveness as the brakes overheat. These temperature ranges describe the simulation, not historical measurements. Brake balance is adjustable in the garage only.
Engine management and endurance
Engine speed and service life
The engine wear model has a reference life of 24 hours at 8,850 rpm and an oil temperature of 105 °C, with no random variation in its initial lifetime. This is a wear reference, not a recommended operating speed or a guaranteed race duration.
At a constant oil temperature, each additional 250 rpm doubles the rate of engine wear. At a constant engine speed, each additional 5.9 °C of oil temperature also doubles the wear rate. The two effects combine. Lower engine speeds and oil temperatures reduce wear relative to those reference conditions.
Fuel
The default fuel load is 95 L and the tank holds up to 189 L. Consumption in L/lap and stint duration have not yet been measured for this specification.
Baseline setup
| Setting | Default | Available adjustment |
|---|---|---|
| Fuel load | 95 L | Up to 189 L |
| Front tyre pressure | 180 kPa (1.80 bar) | 180–230 kPa (1.80–2.30 bar), in 10 kPa (0.10 bar) steps |
| Rear tyre pressure | 180 kPa (1.80 bar) | 180–230 kPa (1.80–2.30 bar), in 10 kPa (0.10 bar) steps |
| Brake balance | 56% front / 44% rear | 54–60% front, in 2 percentage-point steps |
| Brake pressure | 100% | 75–100%, in 5 percentage-point steps |
| Final-drive ratio | 3.269:1 | 3.000:1 / 3.269:1 / 3.542:1 / 3.727:1 / 3.909:1 / 4.500:1 |
These are the current default settings, rather than a circuit-specific race setup.
Pit stops
These are nominal stationary service times for the current LMC car, before variable crew delays. They exclude the drive through the pit lane and are not measured race time losses.
Without repairs
| Selected service | Nominal time |
|---|---|
| Refuelling only | Fuel added in L / 1.65 L/s + 2.5 s for connecting and disconnecting the hose |
| Refuelling only, adding 50 L | 32.8 s |
| Front or rear tyre pair only | 45 s |
| All four tyres only | 100 s (1 min 40 s) |
| Driver change only | 40 s |
| Tyre-pressure adjustment without replacing tyres | 5 s |
With repairs
| Repair work | Nominal work duration |
|---|---|
| Bodywork / aerodynamic damage | 30 s |
| Suspension damage, including detached wheels | 150 s |
Repairs are performed separately from other services and extend the stop. The repair model includes a random-delay allowance of 7.5 s. These are work durations, not complete stop totals; selecting bodywork and suspension repairs can require both operations. Damage also adds 4 s to a driver change.
Planning the stop
Request the stop at least 30 s before reaching the pit box. A late request can add up to 6 s of preparation delay. The crew stands down 150 s after a request if the car has not arrived.
Tyre changes are configured as separate work; refuelling and driver changes permit overlap with eligible services. Do not simply add every row to predict a combined stop. Refuelling, tyre changes, driver changes and damage repairs all have variable delays, so allow a margin and use the in-game pit estimate for the selected operations. Combined service times have not yet been measured in-game.
Specification notes
Specifications checked against the current LMC car on 10 September 2026. Mass excludes fuel. Tyre pressures are garage settings. Power and torque are omitted until figures for the current complete configuration are verified.
