3-4 star
BER airport surroundingsSensible only for very late arrivals or pre-dawn departures; the daily transfer to the congress adds 30-45 minutes each way. Rates are usually lower than central Berlin in December.
Local transport
Get around the city with these convenient transport options.
S-Bahn / airport express (FEX)
Estimated costApprox. EUR 4.40 single, VBB fare zone ABC including the airport
Best forBER airport stations to Berlin city, then onward S-Bahn toward Neukölln
The airport express runs to Berlin Hauptbahnhof and the S-Bahn lines run into the city; from there take an S-Bahn or bus toward Neukölln and walk or take a short taxi to the Estrel campus. Confirm live fares and the current VBB zone rules.
U-Bahn / S-Bahn (inner city)
Estimated costApprox. EUR 3.50 single, VBB fare zone AB
Best forCentral Berlin to Neukölln (for example S-Bahn to Sonnenallee or U-Bahn to Hermannplatz)
Single tickets are valid for a limited period with transfers inside the zone; buy on the app or at a machine and validate before boarding. Confirm live fares.
bus
Estimated costApprox. EUR 3.50 single, VBB fare zone AB
Best forSonnenallee and Neukölln bus corridors to the Estrel campus
Several bus lines run along Sonnenallee; the walk from the nearest stop to the congress entrance is short. Buses are the fallback when the S-Bahn is disrupted.
taxi
Estimated costApprox. EUR 55-75 metered, depending on traffic and luggage
Best forBerlin Brandenburg (BER) to Estrel Berlin
Metered taxis wait at the terminal ranks. The run into Neukölln is roughly 30-45 minutes outside peak hours; ask for the Sonnenallee entrance of the Estrel campus.
ride-hail
Estimated costApprox. EUR 45-70 from BER, with surge pricing at peak times
Best forBER or central Berlin to the Estrel campus
Uber, Bolt and FreeNow operate in Berlin. App pickup points at BER are signposted; check the price shown before confirming during rush hour.
parking
Estimated costApprox. EUR 20-30 per 24 hours, confirm current rate on arrival
Best forEstrel Berlin on-site parking garage
The campus has its own parking; capacity tightens during large congresses. Validate the ticket at the hotel or event desk if a discounted delegate rate is offered.
monthly transit pass
Estimated costApprox. EUR 58 per calendar month, confirm the current 2026 price
Best forDeutschlandticket for unlimited regional and local transport
Useful for a multi-day stay plus city travel; it covers S-Bahn, U-Bahn, tram and bus on local and regional services but not long-distance or express trains. Buy through the official app before arrival.
Weather
Berlin in early December is early winter: expect overcast skies, daytime highs near 3-6 C and night temperatures around -2 to 3 C, with a real chance of frost, sleet or a light snow cover. Rain is more common than snow and often arrives as drizzle, and daylight ends shortly after 16:00, so the walk back from evening sessions is dark. Indoors, congress halls and the exhibition floor are heated, so layering works better than a single heavy coat. Check a local forecast in the final 48 hours and allow extra transfer time if snow or freezing rain is forecast, since Berlin road traffic slows sharply in those conditions.
Plan for the climate
Check temperatures and pack accordingly
Venue connectivity
EU roaming rules apply, so visitors with a SIM from an EU country can use their home allowance in Germany; visitors from outside the EU should check their operator's roaming price or buy a local prepaid eSIM before arrival. German mobile coverage in Berlin and at the Estrel campus is generally good on 4G and 5G. Venue and hotel Wi-Fi exist but shared congress networks slow down during breaks, so download the programme, exhibitor list and any large technical PDFs in advance. Power sockets are Type F at 230 V, and travellers from the UK, US or Asia need a plug adapter; a power bank is useful for long days on the exhibition floor.

Cultural notes
Useful information to help you have a smooth and respectful visit.
Language at the venue
The international Berlin congress normally runs in English, and exhibitor staff generally switch to English for technical discussions. German phrases help in taxis, restaurants and outside the venue; a translation app covers the rest.
Punctuality and dress
Sessions start on time and doors close quietly once a paper begins. Dress is business casual leaning technical: jacket optional, smart trousers and closed shoes are the norm, and comfortable shoes matter for a day on concrete exhibition floors.
Money and tipping
Germany remains partly cash-based, so carry some euro notes for small purchases. Card payment is common in hotels and larger restaurants. Tips of around 5-10 percent are usual, handed to the server while paying rather than left on the table.
December in Berlin
Advent and Christmas markets run through early December and are worth an evening, but they also fill restaurants and hotels, so reserve dinner if you plan to meet contacts after the sessions. Many shops close on Sundays, apart from stations and convenience stores, so buy essentials before the weekend.
Getting around politely
Berliners queue and keep right on escalators. Validate paper transit tickets before boarding, keep phone calls short in quiet carriages, and do not cross against a red pedestrian signal in front of locals, even on an empty street.
Practical guides
Visitor & Exhibitor Essentials
Everything needed to arrive prepared, navigate the event, and make the visit productive.
Flights
Destination: BER
Fly into Berlin Brandenburg (BER), the only commercial airport serving the city, and aim to land by the afternoon before day one so a delay does not cost you the opening session. Direct routes exist from most European hubs; long-haul travellers usually connect through Frankfurt, Munich, Amsterdam, Zurich or London. December weather in northern Europe can cause short delays, so build a buffer and avoid tight same-day connections. Book flexible or refundable fares where possible, check baggage rules if you carry demo hardware, and price the airport transfer into your budget: roughly EUR 4.40 by S-Bahn or EUR 55-75 by taxi each way.
Transport
Get to the venue and around the city with these options.
Airport → venue: Primary gateways: Berlin Brandenburg (BER). Allow road or rail time to Estrel Berlin; on-site parking is usually available at major exhibition venues.
Hotel → venue: Precinct hotels near Estrel Berlin: Neukölln / Estrel campus, Sonnenallee: Estrel Berlin; Neukölln, around Sonnenallee and Hermannplatz: Representative Neukölln midscale hotel; Mitte: Representative Berlin Mitte / Alexanderplatz hotel.
Ride-hail: Uber, Bolt and FreeNow all operate in Berlin, with coverage of the airport, Neukölln and central hotels. From BER, app pickups are at signposted zones outside the terminals and the fare to the Estrel campus usually lands between roughly EUR 45 and EUR 70, with surge pricing during the morning and evening peaks. For short hops around Neukölln, a metered taxi from a rank is often just as quick. Check the price shown in the app before confirming, especially in rain or snow, and keep a screenshot of the destination address in German for drivers.
Public transit: Berlin's network combines S-Bahn, U-Bahn, tram and bus, run under the VBB fare system. From BER, the airport express (FEX) and S-Bahn lines connect to the city, then S-Bahn or buses continue toward Neukölln for the Estrel campus. A single ABC ticket including the airport costs roughly EUR 4.40 and an inner-city AB single roughly EUR 3.50; validate paper tickets before boarding, and note that the Deutschlandticket covers these services if you already hold one. Services are frequent, but check live disruption notices in the evening because engineering works are common on Berlin lines in December.
Parking: The Estrel Berlin has its own parking garage on the campus, which is the closest option for delegates arriving by car; expect roughly EUR 20-30 per 24 hours, and confirm the delegate rate at the hotel desk on arrival. Capacity tightens during large congresses and Christmas-market weekends, so arrive before the morning sessions or use the S-Bahn instead. Berlin operates an environmental zone across the inner city, so check whether your rental car carries the required green emissions sticker. Street parking around Sonnenallee is limited and time-restricted.
Weather
Plan and pack for the event climate.
Month: December 2026 (early winter, short daylight hours)
Temperature: Approx. 3-6 C by day and -2 to 3 C at night; frost is common and colder spells can push daytime highs near 0 C
Seasonality: Overcast skies dominate, with frequent drizzle and occasional sleet or light snow; December is not the wettest month but rain days are common, and daylight fades shortly after 16:00
Packing: Pack an insulated waterproof coat, gloves, scarf and a warm mid-layer, plus shoes with grip for icy pavements. Bring a compact umbrella, and choose layers you can remove indoors because congress halls and exhibition floors are heated. Add a power bank, a Type F plug adapter for non-European devices, and a small bag for the walk between hotel and venue in the dark.

FAQs & glossary
Answers
Frequently asked
Glossary
- Transmission (gearbox)
- The drivetrain component that converts engine or motor speed and torque into the ratio the wheels need. CTI Symposium papers cover stepped automatics, dual-clutch units, dedicated hybrid transmissions and e-axle reduction gears.
- Dual-clutch transmission (DCT)
- A stepped gearbox with two clutches, one per sub-gearbox, so the next gear is pre-selected and shifts happen without interrupting torque. Wet and dry variants and their hybrid integration are recurring congress subjects.
- Dedicated hybrid transmission (DHT)
- A gearbox designed around a hybrid drivetrain from the outset, usually packaging one or more electric machines with clutch packs or a power-split arrangement, rather than adding a motor to an existing gearbox.
- e-Axle
- An integrated electric drive unit combining traction motor, inverter and reduction gear, often with the differential, on one axle. It is one of the standard exhibition categories on the CTI floor.
- Inverter / power electronics
- The converter that turns DC battery voltage into the switched AC the traction motor needs, and back again during recuperation. Switching technology, packaging and 800 V capability dominate the papers.
- Traction motor (PMSM)
- Permanent-magnet synchronous machine, the dominant motor type in battery-electric e-axles; magnet-free, induction and wound-rotor concepts also appear in development papers.
- 800 V architecture
- A higher-voltage electrical system that cuts current for a given power, enabling faster DC charging and thinner cabling. Insulation coordination, partial discharge and thermal design are the engineering consequences discussed at the congress.
- Thermal management
- Cooling and heating of motor, inverter, battery and cabin. In an electric drivetrain it sets continuous power and fast-charging behaviour, which is why it appears in both e-drive and transmission sessions.
- NVH (noise, vibration, harshness)
- Gear whine, motor order noise and driveline vibration. Removing the combustion engine also removes its masking noise, so NVH engineering moves up the agenda for hybrid and electric drivetrains.
- Efficiency map
- A contour plot of motor or transmission efficiency across speed and torque, used to compare drivetrain concepts over WLTP-style operating cycles rather than at a single design point.
- Torque converter
- A hydrodynamic coupling with a lock-up clutch used in classic automatic transmissions; it remains relevant in hybrid automatics where it damps torsional vibration from the engine.
- Regenerative braking
- Recovering kinetic energy through the traction motor into the battery during deceleration. Blending recuperation with friction brakes, and the handover feel, is a controls and calibration topic.
- Powertrain domain controller
- An ECU that consolidates transmission, e-drive and thermal control functions into one unit with shared software. It reflects the shift from standalone gearbox control to software-defined drivetrains.
