Mild HEV and PHEV variants plus TDIs and TSIs are the highlight. Wayne Gerdes – CleanMPG – October 24, 2019 2021 VW Golf VW just introduced the all-new eighth gen Golf with a number of hybrid variants available at launch. Like many of VWs latest offerings, the Golf will arrive with a full digitally generated driver display. Something else… It is the first VW to use “Swarm Intelligence” from traffic via Car2X, meaning it can warn against hazards on an anticipatory basis by communicating with other similar equipped future Golfs, VWs, and Audis going forward. The all-new Golf will be available in the European marketplace in December. No word on when it will be available here yet but I suspect VW will have a great deal to talk about at the LAAS Press Days early next month? From the exterior, not much has changed. A Compact hatch with the distinctive Golf’s 45-years of heritage can be seen from a glance. It is inside and under the hood where things get really interesting. Inside, the majority of displays and controls are digital with the infotainment systems featuring touch buttons and touch sliders. I am not so sure volume and tuning control without buttons/knobs is such a good thing myself. Remember Honda? A heads-up display (HUD) will be available although I have to say that after 10 years of looking at HUDs from a variety of manufacturers, they are distracting and are not exactly a feature I find to be particularly useful. 2021 VW Golf Interior Under the Hood of the all-new Golf The all-new eighth gen Golf will be available in five hybrid variants, three 48V mild hybrids with an eTSI moniker and 2 plug-ins. From our 48V VW Mild-Hybrid reveal, VWs Near Future Electrified Drivetrain Designs, VW/Continental’s 48V technology enables drives to be electrified more affordably. The 48V system via a belt-integrated starter generator (BSG) enables a considerably higher amount of energy to be saved with lower current than a 12V system while allowing some brake regeneration. Like Hyundai’s single motor systems with a BSG but not designed as a full hybrid, VWs starter-generator performs the role of alternator and starter. At the same time, it functions as a small, lightweight electric motor that immediately increases drive torque upon start-up by means of an electric boost. The power of the generator is transferred via a belt. The generator also starts the combustion engine which is switched off as much as possible while the vehicle is moving. Think of it as an electric FAS! The starter generator receives the necessary voltage via the 48V battery and the 12V power supply receives the required voltage via the “DC/DC converter”. Seems like a lot of mild work where the full hybrid would have cost just a few hundred dollars more and the benefits of close to 40 percent would have been provided vs the 10 percent touted within the all-new Golf’s reveal. In Europe, the all-new Golf will be available with three eTSI drivetrains, a 108 hp, 128 hp, and 148 hp variant. I doubt we will see any of these eTSI variants here although that is pure speculation on my part. The eighth generation Golf will also be offered with two different PHEVs in Europe. I suspect we will see at least one of these. A new 201 hp efficiency version and a high power 242 hp “GTE” version are both going to be PHEVs with a 13 kWh Li-Ion. I suspect 70 percent of that that traction battery’s capacity will be useable leaving 9 kWh available allowing upwards of 27 miles of all-electric range prior to first use of gasoline. If VW uses their already excellent 147 hp and 184 pound-feet of torque turbocharged and direct-injected 1.4L I4 engine with a little more atkinsonization - 120 hp engine output, that could indicate an 80 hp electric motor. Again, pure speculation on my part. While the TDI is now an unspoken word here in the U.S., I do wish one were still available, the TSI still lives on in the all-new 8th gen Golf. In Europe, the Golf will be available as an 89 hp and 108 hp I4 TSI under the hood. On the European diesel front, a 113 hp and 148 hp I4 TDI. The TDIs will incorporate 2 SCR Cats to reduce NOx by up to 80% from current TDIs. VW stated the efficiency has climbed another 17% compared with the current TDIs! Bejesus that thing has got to be ridiculously efficient. 2021 VW Golf Car2X “Car to Car” communications will be standard thanks to an online connectivity unit (OCU). The standard OCU features an integrated eSIM “We Connect” and “We Connect Plus”. Car2X receives signals from the traffic infrastructure and information from other vehicles up to .5 miles away via a display. The owners Golf shares its telemetry with other Car2X models providing those vehicles information on traffic conditions from the same distance away. It is called “Swarm Intelligence” and is becoming a reality, representing the beginning of a new phase of traffic safety. Today Google exploits similar technology to provide real time traffic and rerouting options to millions of U.S. drivers on a daily basis today. VW will take this technology to a whole new level.
